INTRODUCTION

       Kid3 is an application to edit the ID3v1 and ID3v2 tags in MP3 files in an efficient way.
       These tags can be edited by most MP3 players, but not in a very comfortable and efficient
       way. Moreover the tags in Ogg/Vorbis, Opus, DSF, FLAC, MPC, APE, MP4/AAC, MP2, Speex,
       TrueAudio, WavPack, WMA, WAV, AIFF files and tracker modules (MOD, S3M, IT, XM) are
       supported too.

       Kid3 does not grab nor encode MP3 files, but it is targeted to edit the ID3 tags of all
       files of an album in an efficient way, i.e. with as few mouse clicks and key strokes as
       possible. Where most other programs can edit either ID3v1 or ID3v2 tags, Kid3 has full
       control over both versions, can convert tags between the two formats and has access to all
       ID3v2 tags. Tags of multiple files can be set to the same value, e.g. the artist, album,
       year and genre of all files of an album typically have the same values and can be set
       together. If the information for the tags is contained in the file name, the tags can be
       automatically set from the file name. It is also possible to set the file name according
       to the tags found in the file in arbitrary formats.

       The editing task is further supported by automatic replacement of characters or
       substrings, for instance to remove illegal characters from filenames. Automatic control of
       upper and lower case characters makes it easy to use a consistent naming scheme in all
       tags.

       The tag information for full albums can be taken from gnudb.org[1], TrackType.org[2],
       MusicBrainz[3], Discogs[4], Amazon[5] or other sources of track lists. The import format
       is freely configurable by regular expressions.

       Please report any problems or feature requests to the author.

   Example Usage
       This section describes a typical session with Kid3. Let's assume we have a directory
       containing MP3 files with the tracks from the album "Let's Tag" from the band "One Hit
       Wonder". The directory is named in the "artist - album" format, in our case One Hit Wonder
       - Let's Tag. The directory contains the tracks in the "track title.mp3" format, which I
       think is useful because the filenames are short (important when using mobile MP3 players
       with small displays) and in the correct order when sorted alphabetically (important when
       using hardware MP3 players which play the tracks in alphabetical order or in the order in
       which they are burnt on CD and that order is alphabetical when using mkisofs). Besides
       this, the artist and album information is already in the directory name and does not have
       to be repeated in the filename. But back to our example, the directory listing looks like
       this:

       01 Intro.mp3

       02 We Only Got This One.mp3

       03 Outro.mp3

       These files have no tags yet and we want to generate them using Kid3. We use Open (File
       menu or toolbar) and select one of the files in this directory. All files will be
       displayed in the file listbox. Lazy as we are, we want to use the information in the
       directory and file names to generate tags. Therefore we select all files, then click the
       To: Tag 1 button in the File section. This will set the title, artist, album and track
       values in all files. To set the year and genre values of all files, we keep all files
       selected and type in "2002" for the Date and select "Pop" from the Genre combobox. To set
       only these two values, their checkboxes are automatically checked and all other checkboxes
       are left unchecked. Now we change the selection by only selecting the first file and we
       see that all tags contain the correct values. The tags of the other files can be verified
       too by selecting them one by one. When we are satisfied with the tags, we use Save (File
       menu or toolbar). Selecting Create Playlist from the File menu will generate a file One
       Hit Wonder - Let's Tag.m3u in the directory.

COMMAND REFERENCE

   The GUI Elements
       The Kid3 GUI is separated in six sections: At the left are the file and directory
       listboxes, the right side contains the File, Tag 1, Tag 2 and Tag 3 sections.

       File List
           The file list contains the names of all the files in the opened directory which match
           the selected file name filter (typically *.mp3 *.ogg *.opus *.dsf *.flac *.mpc *.aac
           *.m4a *.m4b *.m4p *.mp4 *.mp2 *.spx *.tta *.wv *.wma *.wav *.aiff *.ape). A single or
           multiple files can be selected. To select no file, click into the empty area after the
           listbox entries. The selection determines the files which are affected by the
           operations which are available by using the buttons described below.

           Besides Name, also other columns Size, Type, Date Modified with file details can be
           displayed. Columns can be hidden by unchecking their name in the context menu of the
           list header. The order of the columns can be changed by drag and drop. The sort order
           can be toggled by clicking on the column header.

           At the left of the names an icon can be displayed: a disc to show that the file has
           been modified or information about which tags are present (V1, V2, V1V2 or NO TAG, no
           icon is displayed if the file has not been read in yet).

           Directories are displayed with a folder icon. If a directory is opened, its files are
           displayed in a hierarchical tree. By selecting files from subdirectories, operations
           can be executed on files in different directories, which is useful if the music
           collection is organized with a folder for each artist containing folders for albums of
           this artist.

           Clicking the right mouse button inside the file list opens a context menu with the
           following commands:

           ·   Expand all: Expands all folder trees (only the current tree if the shift key is
               pressed)

           ·   Collapse all: Collapses all folder trees

           ·   Rename: Changes the name of a file

           ·   Move to Trash: Moves a file to the trash

           ·   Play: Plays a file, see Play. If the selected file is a playlist, the files of the
               playlist will be played.

           ·   Edit: Edit a playlist, see Edit Playlist.

           ·   The subsequent entries are user commands, which can be defined in the User Actions
               tab of Configure Kid3. The playback on double click can also be activated there.

       Edit Playlist
           A playlist can be created empty or containing the tracks of a folder, see Create
           Playlist. The playlist file created in such a way can be edited by double click or
           using Edit from the file list context menu. A dialog with the entries of the playlist
           is shown. It is possible to open multiple playlists simultaneously.

           New entries can be added by drag and drop from the file list, a file manager or
           another playlist. If an entry is dragged from another playlist, it will be moved or
           copied depending on the system. To invoke the other operation, respectively, the
           Shift, Ctrl or Alt (to copy instead of move on macOS) key has to be pressed.
           Reordering entries within the playlist is also possible via drag and drop.
           Alternatively, entries can be moved using the keyboard shortcuts Ctrl+Shift+Up and
           Ctrl+Shift+Down (on macOS Command has to be pressed instead of Ctrl). An entry can be
           removed using the Delete key.

           Please note the following: To drag entries from the file list, they have to be held at
           the left side (near the icons), the same gesture at the right side will perform a
           multi selection, such an action is hereby still easily possible.

           When a playlist has been modified, the changes can be stored using Save or discarded
           using Cancel. When the window is closed, a confirmation prompt is shown if there are
           unsaved changes.

           Tracks selected in a playlist will be automatically selected in the file list, thereby
           making it possible to edit their tags.

           To execute actions on a playlist, its file must be selected in the file list.  Edit
           from the context menu will lead to the dialog described in this section, and Play will
           start the media player with the tracks from the playlist. User actions can act on
           playlists, for example Export Playlist Folder, which copies the files from a playlist
           into a folder.

       Directory List
           The directory list contains the names of the directories in the opened directory, as
           well as the current (.) and the parent (..) directory. It allows one to quickly change
           the directory without using the Open...  command or drag and drop.

           Column visibility, order and sorting can be configured as described in the section
           about the file list.

       File
           Shows information about the encoding (MP3, Ogg, Opus, DSF, FLAC, MPC, APE, MP2, MP4,
           AAC, Speex, TrueAudio, WavPack, WMA, WAV, AIFF), bit rate, sample rate, channels and
           the length of the file.

           The Name line edit contains the name of the file (if only a single file is selected).
           If this name is changed, the file will be renamed when the Save command is used.

           The Format combo box and line edit contains the format to be used when the filename is
           generated from the first or the second tag. The filename can contain arbitrary
           characters, even a directory part separated by a slash from the file name, but that
           directory must already exist for the renaming to succeed. The following special codes
           are used to insert tag values into the filename:

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track (e.g. 01)

           ·   %t %{track.n} Track with field width n (e.g. 001 for %{track.3})

           ·   %T %{tracknumber} Track (without leading zeros, e.g. 1)

           ·   %g %{genre} Genre

           ·   %{ignore} Ignored when generating tags from the file name

           The format codes are not restricted to the examples given above. Any frame name can be
           used, for instance unified frame names like %{albumartist}, %{discnumber.1}, %{bpm} or
           format specific names like %{popm}.

           It is possible to prepend and append strings to the replacement for a format code by
           adding them in double quotes inside the curly braces of a format code. These strings
           will only be put into the resulting string if the format code yields a nonempty value.
           For example, if the file name shall both contain the title and the subtitle, one could
           use %{title} [%{subtitle}] in the format string. But this would result in a string
           ending with [] if no subtitle frame exists for a file. In order to omit the brackets
           if no subtitle is present, %{title}%{" ["subtitle"]"} shall be used instead. This will
           omit the brackets, the leading space and the subtitle if not subtitle exists.

           The list of available formats can be edited in the dialog which appears when clicking
           the Filename from tag button in the File tab of the settings.

           A second Format combo box (with arrow down) is used to generate the tags from the
           filename. If the format of the filename does not match this pattern, a few other
           commonly used formats are tried.

           Some commonly used filename formats are already available in the combo box, but it is
           also possible to type in some special format into the line edit.

           The list of available formats can be edited in the dialog which appears when clicking
           the Tag from filename button in the File tab of the settings.

           Internally, a regular expression is built from the format codes. If advanced regular
           expressions are required, the format to generate the tags from the filenames can be
           given as a complete regular expression with captures which are preceded by the format
           codes, e.g. to extract the track numbers without removal of leading zeros, a format
           like "/%{track}(\d+) %{title}(.*)" could be used.

           From: Tag 1, Tag 2: Sets the filename using the selected format and the first tag or
           the second tag, respectively.

           To: Tag 1, Tag 2: The tags are set from the filename. First, the format specified in
           Format is used. If the existing filename does not match this format, the following
           formats are tried:

           ·   Artist - Album/Track Song

           ·   Album/Track - Artist - Song

           ·   /Artist - Album - Track - Song

           ·   Album/Artist - Track - Song

           ·   Album/Artist - Song

           ·   Artist/Album/Track Song

           If a single file is selected, the GUI controls are filled with the values extracted
           from the filename. If multiple files are selected, the tags of the files are directly
           set according to the filenames.

       Tag 1
           The line edit widgets for Title, Artist, Album, Comment, Date, Track Number and Genre
           are used to edit the corresponding value in the first tag of the selected files. The
           value will be changed when the file selection is altered or before operations like
           Save and Quit and when the corresponding check box at the left of the field name is
           checked. This is useful to change only some values and leave the other values
           unchanged.

           If a single file is selected, all check boxes are checked and the line edit widgets
           contain the values found in the tags of this file. If a tag is not found in the file,
           the corresponding empty value is displayed, which is an empty string for the Title,
           Artist, Album and Comment line edits, 0 for the numerical Date and Track Number edits
           and an empty selected value for the Genre combo box. The values can be changed and if
           the corresponding check box is checked, they will be set for the selected file after
           the selection is changed. The file is then marked as modified by a disk symbol in the
           file listbox but remains unchanged until the Save command is used.

           If multiple files are selected, only the values which are identical in all selected
           files are displayed. In all other controls, the empty values as described above are
           displayed. All check boxes are unchecked to avoid unwanted changes. If a value has to
           be set for all selected files, it can be edited and the checkbox has to be set. The
           values will be set for all selected files when the selection is changed and can be
           saved using the Save command.

           The check boxes also control the operation of most commands affecting the tags, such
           as copy, paste and transfer between tags 1 and 2. To make it easier to use with
           multiple files where all check boxes are unchecked, these commands behave in the same
           way when all check boxes are checked and when all check boxes are unchecked.

           From Tag 2: The tag 1 fields are set from the corresponding values in tag 2. If a
           single file is selected, the GUI controls are filled with the values from tag 2. If
           multiple files are selected, the tags of the files are directly set.

           Copy: The copy buffer is filled with the Tag 1 values. Only values with checked
           checkbox will be used in subsequent Paste commands.

           Paste: Pastes the values from the copy buffer into the GUI controls.

           Remove: This will set all GUI controls to their empty values which results in removing
           all values. The saved file will then contain no tag 1.

       Tag 2
           The GUI controls function in the same way as described for the Tag 1 section, but the
           size of the strings is not limited.

           For the tag 2 Genre you can also use your own names besides the genres listed in the
           combo box, just type the name into the line edit.

           The tag 2 can not only contain the same values as the tag 1, the format is built in a
           flexible way from several frames which are themselves composed of several fields. The
           tag 2 table shows all the frames which are available in the selected file.

           Edit: This will open a window which allows one to edit all fields of the selected
           frame. If multiple files are selected, the edited fields are applied to all selected
           files which contain such a frame.

           Add: A requester to select the frame type will appear and a frame of the selected type
           can be edited and added to the file. This works also to add a frame to multiple
           selected files.

           Delete: Deletes the selected frame in the selected files.

           Drag album artwork here is shown if the file does not contain embedded cover art. A
           picture can be added using drag and drop from a browser or file manager and will be
           displayed here. Picture frames can be edited or added by double clicking on this
           control.

       Tag 3
           Some files can have more than two tags, and a third tag section is visible. The
           following file types can have such a Tag 3 section:

           ·   MP3 files can have an ID3v1.1 tag, an ID3v2 (2.3.0 or 2.4.0) tag and in the third
               section an APE tag. Such APE tags are used for replay gain information. In the Tag
               3 section, this information is visible, and the APE tag can be removed with the
               Remove button.

           ·   The RIFF INFO chunk of WAV files is available in the Tag 3 section because the Tag
               1 section is dedicated to ID3v1.1 tags and handles their restrictions. The Tag 2
               is still used for ID3v2.4.0 tags, which are also supported for WAV files, but RIFF
               INFO chunks seem to be supported better.

           ·   FLAC files normally use a Vorbis comment for their meta data. However, there are
               FLAC files which have IDv1 and ID3v2 tags, which can be found in the Tag 1 and Tag
               3 sections. ID3 tags in FLAC files are only supported by TagLib, therefore the
               OggFlacMetadata plugin has to be disabled in the Plugins tab of the settings.

           The GUI controls work in the same way as in the Tag 2 section.

       Synchronized Lyrics and Event Timing Codes
           For information synchronized with the audio data, a specific editor is available.
           These frames are supported for ID3v2.3.0 and ID3v2.4.0 tags. To add such a frame, the
           specific frame name has to be selected in the list which appears when the Add button
           is clicked - Synchronized Lyrics or Event Timing Codes, respectively. The editor is
           the same for both types, for the event timing codes, only a predefined set of events
           is available whereas for the synchronized lyrics, text has to be entered. In the
           following, editing synchronized lyrics is explained.

           A file having an ID3v2 tag is selected, the lyrics editor is entered using Add and
           selecting Synchronized Lyrics. For an existing Synchronized Lyrics frame, it is
           selected and Edit is clicked. The player is automatically opened with the current file
           so that the file can be played and paused to synchronize lyrics.

           The settings at the top of the SYLT editor normally do not have to be changed. If the
           lyrics contains characters which are not present in the Latin 1 character set,
           changing the text encoding to UTF16 (or UTF8 for ID3v2.4.0) is advisable. For English
           lyrics and maximum compatibility, ISO-8859-1 should be used.

           The Lyrics section has five buttons at the top.  Add will add a new time event in the
           table. The time is taken from the position of the player, thus adding an entry while
           playing the track will add a line for the currently played position. The events in the
           table have to be chronologically ordered, therefore the row will be inserted
           accordingly. Entries with an invalid time are treated specially: If the currently
           selected row has an invalid time, its time stamp will be replaced by the current time
           instead of adding a new row. If the current time is not invalid, the first row with an
           invalid time will be used if present. This behavior should facilitate adding time
           stamps if the lyrics text is already in the table but the time stamps are missing
           (which is the case when importing unsynchronized lyrics). Note that the invalid time
           is represented as 00:00.00, i.e. the same as the time at the absolute beginning of the
           track, which is not invalid. To make a time invalid, press the Delete key, or use
           Clear from the context menu. New rows inserted using Insert row from the context menu
           or created when importing unsynchronized lyrics with From Clipboard or Import also
           contain invalid time stamps. Rows in the table can be deleted by clicking the Delete
           button or using Delete rows from the context menu.

           Synchronized lyrics can be imported from a file using Import. The expected format is
           simple or enhanced LRC. If the selected file does not contain a square bracket in the
           first line, it is supposed to be a simple text file with unsynchronized lyrics. The
           lines from such a file are then imported having invalid time stamps. The time
           information can be added using the Add button or by manual entry. It is also possible
           to import lyrics via copy-paste using From Clipboard. Synchronized lyrics can be
           written to LRC files using Export. Note that only entries with valid time stamps will
           be exported and that the entries will be sorted by time. Entries with invalid time
           won't be stored in the SYLT frame either, so make sure to include all timing
           information before leaving the dialog.

           The ID3 specification[6] suggests a time stamp for each syllable. However most players
           only support the granularity of a line or sentence. To support both use cases, Kid3
           follows the same conventions as SYLT Editor[7]. Text which is entered into the table
           is assumed to start a new line unless it starts with a space or a hyphen. Exceptions
           to this rule are possible by starting a line with an underscore ('_') to force
           continuation or a hash mark ('#') to force a new line. These escape characters are not
           stored inside the SYLT frame. Inside the SYLT frame, new lines start with a line feed
           character (hex 0A) whereas continuations do not. When reading SYLT frames, Kid3 checks
           if the first entry starts with a line feed. If this is not the case, it is assumed
           that all entries are new lines and that no syllable continuations are used.

           While the track is played, the row associated with the current playing position is
           highlighted, so that the correctness of the synchronization information can be
           verified. If an offset has to be added to one or more time stamps, this can be
           accomplished with the Add offset context menu. Negative values can be used to reduce
           the time. Using Seek to position in the context menu, it is possible to set the
           playing position to the time of the selected row.

           Recommended procedure to add new synchronized lyrics

           ·   Get the unsynchronized lyrics, e.g. using Lyrics → Embed Lyrics from the file list
               context menu.

           ·   Copy the unsynchronized lyrics to the clipboard, just go to the Lyrics row in the
               frame table and press Ctrl+C.

           ·   Add a synchronized lyrics frame (Add..., Synchronized Lyrics, OK), click From
               Clipboard.

           ·   Now all lines from the unsynchronized lyrics are in the table, all time stamps are
               invalid (0:0:0.00). You can delete empty entries beforehand.

           ·   Start playing the song by clicking the play button ► in the play toolbar at the
               bottom of the main window.

           ·   When the next lyrics line with invalid timestamp comes, click Add or press Alt+A,
               the timestamp will be updated.

           ·   Continue like this until all timestamps are set. If you missed something, stop
               playback and clear the timestamps using the Delete key or by selecting them and
               using Clear from the context menu. To restart playback from a given timestamp, use
               Seek to position from the context menu.

   The File Menu
       File → Open... (Ctrl+O)
           Opens a directory.  All files matching the selected file name filter will be displayed
           in the file listbox and the chosen file is selected.

       File → Open Recent
           Opens a recently opened directory.

       File → Open Directory... (Ctrl+D)
           Opens a directory.  All files matching the selected file name filter will be displayed
           in the file listbox.

       File → Reload (F5)
           Reload directory.  Modified files have to be saved before. Expanded subfolders will be
           collapsed.

       File → Save (Ctrl+S)
           Saves all changed files in the directory.  The changed files are marked with a disk
           symbol in the file listbox. If any file names have been changed, those files will be
           renamed.

       File → Revert
           Reverts the changes of one or multiple files.  If no files are selected in the file
           listbox, the changes of all files will be reverted, else only the changes of the
           selected files are reverted.

       File → Import...
           The Import dialog can be used to import data directly from a freedb.org server, from a
           MusicBrainz server, from Discogs, Amazon or other sources of album track lists in
           textual format.

           Import from a freedb.org server is possible using a dialog which appears when From
           Server: gnudb.org or TrackType.org is selected. The artist and album name to search
           for can be entered in the two topmost fields, the albums which match the query will be
           displayed when Find is clicked and the results from www.gnudb.org[8] are received.
           Importing the track data for an album is done by double-clicking the album in the
           list. The freedb.org server to import from can be selected as well as the CGI path.
           The imported data is displayed in the preview table of the import dialog. When
           satisfied with the displayed tracks, they can be imported by terminating the import
           dialog with OK.

           A search on the Discogs server can be performed using Discogs. As in the gnudb.org
           dialog, you can enter artist and album and then choose from a list of releases. If
           Standard Tags is marked, the standard information is imported, e.g. artist, album, and
           title. If Additional Tags is marked, more information is imported if available, e.g.
           performers, arrangers, or the publisher. If Cover Art is marked, cover art will be
           downloaded if available.

           A search on Amazon can be performed using Amazon. As in the gnudb.org dialog, you can
           enter artist and album and then choose from a list of releases. If Additional Tags is
           marked, more information is imported if available, e.g. performers, arrangers, or the
           publisher. If Cover Art is marked, cover art will be downloaded if available.

           You can search in the same way in the release database of MusicBrainz using From
           MusicBrainz Release. The workflow is the same as described for From gnudb.org.

           Import from a MusicBrainz server is possible using the dialog which appears when From
           MusicBrainz Fingerprint is selected. The Server can be selected as in the freedb
           import dialog. Below is a table displaying the imported track data. The right column
           shows the state of the MusicBrainz query, which starts with "Pending" when the dialog
           is opened. Then the fingerprint is looked up and if it does not yield a result,
           another lookup using the tags in the file is tried. Thus it can be helpful for a
           successful MusicBrainz query to store known information (e.g. artist and album) in the
           tags before the import. If a result was found, the search ends in the state
           "Recognized", otherwise nothing was found or multiple ambiguous results and one of
           them has to be selected by the user.  OK and Apply use the imported data, Cancel
           closes the dialog. The closing can take a while since the whole MusicBrainz machinery
           has to be shut down.

           For the import of textual data, From File/Clipboard opens a subdialog, where several
           preconfigured import formats are available. The first two, "CSV unquoted" and "CSV
           quoted" can be used to import data which was exported by the Export dialog. The CSV
           data can be edited with a spreadsheet, and shall be written using tabs as delimiters.
           Import should then be possible using "CSV quoted", which is more flexible than "CSV
           unquoted". However, its fields cannot contain any double quotes. If you only export
           from Kid3 and import later, "CSV unquoted" can be used as a simple format for this
           purpose. Note that there are also "Export CSV" and "Import CSV" commands in the
           context menu of the file list, which use scripts to export and import CSV data in a
           more complete, powerful and flexible way.

           The next format, "freedb HTML text", can be used to copy information from an HTML page
           of freedb.org[9]. Search an album in freedb and if the desired information is
           displayed in the web browser, copy the contents to the clipboard. Then click the From
           Clipboard button and the imported tracks will be displayed in the preview table at the
           top of the dialog. If you are satisfied with the imported data, terminate the dialog
           with OK, which will insert the data into the tags of the current directory. The
           destination (Tag 1, Tag 2 or Tag 1 and Tag 2) can be selected with a combo box. The
           files in the current directory should be in the correct track order to get their tags
           assigned. This is the case if they are numbered.

           The next preconfigured import format, "freedb HTML source", can be used, if the data
           is available as an HTML document. Import is possible using the From File button, which
           opens a file selector, or copying its contents from an editor and then importing from
           clipboard. This format can be useful for offline import, although the HTML document
           could also be opened in a browser and then be imported in the first format via the
           clipboard.

           More preconfigured formats, e.g. "Track Title Time", are available. An empty custom
           format can be created with Add to be set by the user. Two lines below the format name
           can be set with a regular expression to capture the fields from the import text. The
           first regular expression will be parsed once per document to gather per-album data
           such as artist, album, year and genre. The second line is tried to match from the
           start of the document to the end to get track data, usually number and title. The
           regular expressions include all the features offered by Qt, which is most of the what
           Perl offers. Bracketing constructs "(..)" create capture buffers for the fields to
           import and are preceded by Kid3 specific codes to specify which field to capture. The
           codes are the same as used for the filename format, besides the codes listed below,
           any frame name is possible:

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track

           ·   %g %{genre} Genre

           ·   %d %{duration} Duration

           For example, a track regular expression (second line) to import from an .m3u playlist
           could be "%{track}(\d+)\s+%{title}(\S[^\r\n]*)\.mp3[\r\n]". All formats can be changed
           by editing the regular expressions and the name and then clicking Save Settings. They
           will be stored in the kid3rc file in the configuration directory. This file can be
           directly edited to have more import formats or it can be deleted to revert to the
           default formats. Formats can be deleted using Remove.

           Accuracy shows an estimation of how good the imported information matches the given
           tracks. It uses track durations or file names to calculate the level of similarity in
           percent.  Cover Art shows the URL of the album cover image which will be downloaded.

           To check whether the imported tracks match the current set of files, the duration of
           the imported tracks can be compared with the duration of the files. This option can be
           enabled with the checkbox Check maximum allowable time difference and the maximum
           tolerated difference in time can be set in seconds. If a mismatch in a length is
           detected, the length is displayed with a red background in the preview table.

           If the files are ordered differently than the imported tracks, their assigned tracks
           have to be changed. This task can be facilitated using the Match with buttons Length,
           Track, and Title, which will reorder the tracks according to the corresponding field.
           To correct the assignments manually, a track can be dragged with the left mouse button
           and the Ctrl key hold down, and then dropped at the new location.

           When the import dialog is opened, it contains the actual contents of the tags. The tag
           type (Tag 1, Tag 2, Tag 1 and Tag 2) can be selected using the Destination combo box.
           The button on the right of this combo box can be used to revert the table to the
           current contents of the tags. The checkboxes in the first table column can be used to
           select the tracks which are imported. This can be useful if a folder contains the
           tracks of both CDs of a double CD and only the tracks of the second CD have to be
           imported.

           To identify the tracks which are imported, it is possible to display the file names or
           the full paths to the files using the context menu of the table header. The values in
           the import table can be edited. The revert-button to the right of the Destination
           combo box can be used to restore the contents of the tags, which can also be useful
           after changing the Destination.

           Almost all dialogs feature a Save Settings button, which can be used to store the
           dialog specific settings and the window size persistently.

           From Tags leads to a subdialog to set tag frames from the contents of other tag
           frames. This can be used to simply copy information between tags or extract a part
           from one frame and insert it in another.

           As in the import from file/clipboard dialog, there are freely configurable formats to
           perform different operations. Already preconfigured are formats to copy the Album
           value to Album Artist, Composer or Conductor, and to extract the Track Number from
           Title fields which contain a number. There is also a format to extract a Subtitle from
           a Title field.

           The following example explains how to add a custom format, which sets the information
           from the Subtitle field also in the Comment field. Create a new format using Add and
           set a new name, e.g. "Subtitle to Comment". Then enter "%{subtitle}" in Source and
           "%{comment}(.*)" for Extraction and click Save Settings.

           The expression in Source can contain format codes for arbitrary tag frames, multiple
           codes can be used to combine the contents from different frames. For each track, a
           text is generated from its tags using the Source format, and the regular expression
           from Extraction is applied to this text to set new values for the tags. Format codes
           are used before the capturing parentheses to specify the tag frame where the captured
           text shall be stored. It works in the same way as for the import from file/clipboard.

       File → Import from gnudb.org...
           Import from a freedb.org server using gnudb.org album search.  This menu item opens
           the same import dialog as Import..., but opens directly the gnudb.org dialog.

       File → Import from TrackType.org...
           Import from the TrackType.org server.  This menu item opens the same import dialog as
           Import..., but opens directly the TrackType.org dialog.

       File → Import from Discogs...
           Import from the Discogs server.  This menu item opens the same import dialog as
           Import..., but opens directly the From Discogs dialog.

       File → Import from Amazon...
           Import from Amazon.  This menu item opens the same import dialog as Import..., but
           opens directly the From Amazon dialog.

       File → Import from MusicBrainz Release...
           Import from the MusicBrainz release database.  This menu item opens the same import
           dialog as Import..., but opens directly the From MusicBrainz Release dialog.

       File → Import from MusicBrainz Fingerprint...
           Import from a MusicBrainz server.  This menu item opens the same import dialog as
           Import..., but opens directly the From MusicBrainz Fingerprint dialog.

       File → Automatic Import...
           Automatic Import allows one to import information for multiple albums from various web
           services. If directories are selected in the file list, track data for the selected
           directories will be imported. If no directory is selected, all directories in the file
           list will be imported.

           The tag type (Tag 1, Tag 2, Tag 1 and Tag 2) can be selected using the Destination
           combo box.

           Profiles determine which servers will be contacted to fetch album information. Some
           profiles are predefined (All, MusicBrainz, Discogs, Cover Art), custom profiles can be
           added using the Add button at the right of the Profile combo box.

           The table below shows the servers which will be used when importing album information
           using the selected profile. The import process for an album is finished if all
           required information has been found, so the order of the rows in the table is
           important. It can be changed using the Move Up and Move Down buttons.  Edit can be
           used to change an existing entry. The Server selection offers the same servers as can
           be used in the import functions.  Standard Tags, Additional Tags, Cover Art determine
           the information which shall be fetched from the server. Finally, Accuracy is the
           minimum accuracy which must be achieved to accept the imported data. If the accuracy
           is insufficient, the next server in the list will be tried. The same dialog containing
           the server properties appears when Add is clicked to add a new server entry. Existing
           entries can be deleted using Remove.

           To launch an automatic batch import with the selected profile, click Start. Details
           about the running import are displayed at the top of the dialog. The process can be
           aborted with the Abort button.

       File → Browse Cover Art...
           The Browse Cover Art dialog helps to find album cover art.  Artist/Album is filled
           from the tags if possible.  Source offers a variety of websites with album cover art.
           The URL with artist and album as parameters can be found beneath the name. URL-encoded
           values for artist and album can be inserted using %u{artist} and %u{album}, other
           values from the tags are possible too, as described in Configure Kid3, User Actions.
           More sources can be entered after the entry "Custom Source" by replacing "Custom
           Source" with the source's name, pressing Enter, then inserting the URL and finally
           pressing Save Settings. The resulting browser command is displayed at the top of the
           dialog and can be started by clicking Browse. The browser, which can be configured in
           the settings, is started with the selected source. A cover image can then be dragged
           from the browser into the Kid3 window and will be set in the picture frame of the
           selected files.

           Because not all browsers support drag and drop of images and the pictures on websites
           often have a URL, in such cases Kid3 will receive the URL and not the picture. If the
           URL points to a picture, it will be downloaded. However, if the URL refers to some
           other web resource, it has to be translated to the corresponding picture. Such
           mappings are defined in the table URL extraction. The left column Match contains a
           regular expression which is compared with the URL. If it matches, the captured
           expressions in parentheses are inserted into the pattern of the right Picture URL
           column (at the positions marked with \1 etc.). The replaced regular expression
           contains the URL of the picture. By this means cover art can be imported from Amazon,
           Google Images, etc. using drag and drop. It is also possible to define your own
           mappings.

       File → Export...
           The Export Dialog is used to store data from the tags in a file or the clipboard. The
           editor at the top shows a preview of the data to export. If the export data contain
           tabulator characters, the export is displayed in a table. The data will be generated
           from the tags in the current directory according to the configured format.

           The format settings are similar as in the Import dialog: The topmost field contains
           the title (e.g. "CSV unquoted"), followed by the header, which will be generated at
           the begin of the file. The track data follows; it is used for every track. Finally,
           the trailer can be used to generate some finishing text.

           The format fields do not contain regular expressions as in the Import dialog, but only
           output format expressions with special %-expressions, which will be replaced by values
           from the tags. The whole thing works like the file name format, and the same codes are
           used plus some additional codes. Not only the codes listed below but all tag frame
           names can be used.

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track (e.g. 01)

           ·   %t %{track.n} Track with field width n (e.g. 001 for %{track.3})

           ·   %T %{tracknumber} Track (without leading zeros, e.g. 1)

           ·   %g %{genre} Genre

           ·   %f %{file} File name

           ·   %p %{filepath} Path

           ·   %u %{url} URL

           ·   %{dirname} Directory name

           ·   %d %{duration} Duration in minutes:seconds

           ·   %D %{seconds} Duration in seconds

           ·   %n %{tracks} Number of tracks of the album

           ·   %e %{extension} File extension

           ·   %O %{tag1} The format of tag 1 (ID3v1.1 or empty if not existing)

           ·   %o %{tag2} The format of tag 2 (ID3v2.3.0, ID3v2.4.0, ID3v2.2.0, ID3v2.2.1,
               Vorbis, APE, MP4, ASF, or empty if not existing)

           ·   %b %{bitrate} Bit rate in kbit/s

           ·   %v %{vbr} VBR or empty (only for ID3v2.3 with id3lib)

           ·   %r %{samplerate} Sample rate in Hz

           ·   %m %{mode} Channel mode (Stereo or Joint Stereo)

           ·   %h %{channels} Number of channels (1 or 2)

           ·   %k %{codec} Codec (e.g. MPEG 1 Layer 3, MP4, Ogg Vorbis, FLAC, MPC, APE, ASF,
               AIFF, WAV)

           A few formats are predefined. "CSV unquoted" separates the fields by tabs. Data in
           this format can be imported again into Kid3 using the import format with the same
           name. "CSV quoted" additionally encloses the fields by double quotes, which eases the
           import into spreadsheet applications. However, the fields shall not contain any double
           quotes when this format is used. "Extended M3U" and "Extended PLS" generate playlists
           with extended attributes and absolute path names. "HTML" can be used to generate an
           HTML page with hyperlinks to the tracks. "Kover XML" creates a file which can be
           imported by the cover printing program Kover. "Technical Details" provides information
           about bit rate, sample rate, channels, etc. Finally, "Custom Format" is left empty for
           definition of a custom format. You can define more formats of your own by adding lines
           in the file kid3rc in the configuration directory. The other formats can be adapted to
           your needs.

           The source of the tags to generate the export data (Tag 1 or Tag 2) can be selected
           with a combo box. Pushing To File or To Clipboard stores the data in a file or on the
           clipboard.  OK and Cancel close the dialog, whereas OK accepts the current dialog
           settings.

       File → Create Playlist
           Creates a playlist.  The format and contents of the playlist can be set by various
           options.

           The name of the playlist can be the Same as directory name or use a Format with values
           from the tags, e.g. "%{artist} - %{album}" to have the artist and album name in the
           playlist file name. The format codes are the same as for Export.  Create new empty
           playlist will make an empty playlist with the given name. The extension depends on the
           playlist format.

           The location of the generated playlist is determined by the selection of the Create in
           combo box.

           Current directory
               The playlist is created in the current directory and contains only files of the
               current directory. The current directory is the directory where the current file
               is located. If multiple files are selected, the current file is probably the last
               selected file.

           Every directory
               A playlist is created in every directory which contains listed files, and each
               playlist contains the files of that directory.

           Top-level directory
               Only one playlist is created in the top-level directory (i.e. the directory of the
               file list) and it contains the listed files of the top-level directory and all of
               its sub-directories.

           The Format of the playlist can be M3U, PLS or XSPF.

           If Include only the selected files is checked, only the selected files will be
           included in the playlist. If a directory is selected, all of its files are selected.
           If this check box is not activated, all audio files are included in the playlist.

           Sort by file name selects the usual case where the files are ordered by file name.
           With Sort by tag field, it is possible to sort by a format string with values from tag
           fields. For instance, "%{track.3}" can be used to sort by track number (the ".3" is
           used to get three digits with leading zeros because strings are used for sorting). It
           is also possible to use multiple fields, e.g. "%{genre}%{year}" to sort using a string
           composed of genre and year.

           The playlist entries will have relative or absolute file paths depending on whether
           Use relative path for files in playlist or Use full path for files in playlist is set.

           When Write only list of files is set, the playlist will only contain the paths to the
           files. To generate an extended playlist with additional information, a format string
           can be set using the Write info using control.

       File → Quit (Ctrl+Q)
           Quits the application.

   The Edit Menu
       Edit → Select All (Alt+A)
           Selects all files.

       Edit → Deselect (Ctrl+Shift+A)
           Deselects all files.

       Edit → Select All in Directory
           Selects all files of the current directory.

       Edit → Previous File (Alt+Up)
           Selects the previous file.

       Edit → Next File (Alt+Down)
           Selects the next file.

       Edit → Find... (Ctrl+F)
           Find strings in the file names and the tags. The Find dialog is a subset of the
           Replace dialog, which is described below.

       Edit → Replace... (Ctrl+R)
           This function opens a dialog to find and replace strings in the file names and the
           tags. The set of frames where the search is performed can be restricted by
           deactivating the Select all checkbox and selecting the frames which shall be searched.
           There are also search options available to search backwards, case sensitively, and to
           use regular expressions.

           Depending on the number of files, the search might take some time, therefore it can be
           aborted by closing the dialog.

   The Tools Menu
       Tools → Apply Filename Format
           When Automatically apply format is switched off for the filename format in the
           configuration dialog, this menu item can be used to apply the configured format to the
           names of the selected files. This can also be used to check whether the file names
           conform with the configured format by applying the format to all saved files and then
           checking if any files were changed (and therefore marked with a disk symbol in the
           file listbox).

       Tools → Apply Tag Format
           When Automatically apply format is switched off for the tag format in the
           configuration dialog, this menu item can be used to apply the configured format to the
           tags of the selected files. This can also be used to check whether the tags conform
           with the configured format by applying the format to all saved files and then checking
           if any files were changed (and therefore marked with a disk symbol in the file
           listbox).

       Tools → Apply Text Encoding
           Sets the Text encoding selected in Settings/Configure Kid3.../Tags/Tag 2 for all
           selected files. If UTF8 is selected, UTF16 will be used for ID3v2.3.0 tags because
           UTF8 is not supported for this format.

       Tools → Rename Directory...
           This dialog offers the possibility to automatically rename the currently open
           directory according to the tags in the files. Several formats are preconfigured to
           include information about artist, album and year in the directory name. It is also
           possible to set a custom format and Edit the list of available formats. The following
           special codes are used to insert tag values into the directory name:

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track (e.g. 01)

           ·   %t %{track.n} Track with field width n (e.g. 001 for %{track.3})

           ·   %T %{tracknumber} Track (without leading zeros, e.g. 1)

           ·   %g %{genre} Genre

           ·   %{dirname} Directory name (e.g. %{year" "}%{dirname} will prepend the year to the
               current directory name)

           ·   %{max-year} The maximum year value found for this directory, can also be used with
               other codes than "year"

           ·   %{min-year} The minimum year value found for this directory

           ·   %{unq-year} The unique year value found for this directory or empty if not unique

           If a directory separator "/" is found in the format, multiple directories are created.
           If you want to create a new directory instead of renaming the current directory,
           select Create Directory instead of Rename Directory. The source of the tag information
           can be chosen between From Tag 1 and Tag 2, From Tag 1 and From Tag 2. A preview for
           the rename operation performed on the first file can be seen in the From and To
           sections of the dialog.

           Multiple directories can be renamed by selecting them.

       Tools → Number Tracks...
           If the track numbers in the tags are not set or have the wrong values, this function
           can number the tracks automatically in ascending order. The start number can be set in
           the dialog. If only part of the tracks have to be numbered, they must be selected.

           When Total number of tracks is checked, the number of tracks will also be set in the
           tags.

           It is possible to number the tracks over multiple directories. The folders have to be
           expanded and selected.

           If Reset counter for each directory is checked, track numbering is restarted with the
           given number for each directory when multiple folders are selected.

           The number tracks dialog can also be used to format existing track numbers without
           changing the values when the check box left to Start number is deactivated. The total
           number of tracks will be added if the corresponding check box is active, which can be
           used to set the total for all selected tracks. If only formatting of the existing
           numbers is desired, this check box has to be deactivated too.

       Tools → Filter...
           The filter can be used to display only those files which match certain criteria. This
           is helpful if you want to organize a large collection and only edit those files which
           are not in the desired scheme. The expression defining which files to display uses the
           same format codes which are used in the file name format, import and export.

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track (e.g. 01)

           ·   %t %{track.n} Track with field width n (e.g. 001 for %{track.3})

           ·   %T %{tracknumber} Track (without leading zeros, e.g. 1)

           ·   %g %{genre} Genre

           ·   %f %{file} File name

           ·   %p %{filepath} Absolute path to file

           ·   %e %{extension} File extension

           ·   %O %{tag1} The format of tag 1 (ID3v1.1 or empty if not existing)

           ·   %o %{tag2} The format of tag 2 (ID3v2.3.0, ID3v2.4.0, ID3v2.2.0, ID3v2.2.1,
               Vorbis, APE, MP4, ASF, or empty if not existing)

           ·   %b %{bitrate} Bit rate in kbit/s

           ·   %v %{vbr} VBR or empty (only for ID3v2.3 with id3lib)

           ·   %r %{samplerate} Sample rate in Hz

           ·   %m %{mode} Channel mode (Stereo or Joint Stereo)

           ·   %h %{channels} Number of channels (1 or 2)

           ·   %k %{codec} Codec (e.g. MPEG 1 Layer 3, MP4, Ogg Vorbis, FLAC, MPC, APE, ASF,
               AIFF, WAV)

           ·   %w %{marked} Marked, is 1 if the file is marked (e.g. because of truncation or
               standard violation), empty otherwise

           ·   %1a %1{artist}, ... Use the prefix 1 to get values of tag 1

           ·   %2a %2{artist}, ... Use the prefix 2 to get values of tag 2

           These codes are replaced with the values for the file, and the resulting strings can
           be compared with the following operations:

           ·   s1 equals s2: true if s1 and s2 are equal.

           ·   s1 contains s2: true if s1 contains s2, i.e. s2 is a substring of s1.

           ·   s matches re: true if s matches the regular expression re.

           True expressions are replaced by 1, false by 0. True values are represented by 1,
           true, on and yes, false values by 0, false, off and no. Boolean operations are not,
           and, or (in this order of precedence) and can be grouped by parentheses.

           Some filter rules are predefined and can serve as examples for your own expressions:

           All
               When the file list is filtered - this is shown by "[filtered]" in the window title
               - and all files shall be displayed again, the filtering can be reverted using this
               filter. It uses an empty expression, but a true value would have the same effect.

           Filename Tag Mismatch
                not (%{filepath} contains "%{artist} - %{album}/%{track} %{title}")

               Tests if the file path conforms with the file name format. This rule is
               automatically adapted if the file name format changes.

           No Tag 1
                %{tag1} equals ""

               Displays only files which do not have a tag 1.

           No Tag 2
                %{tag2} equals ""

               Displays only files which do not have a tag 2.

           ID3v2.3.0 Tag
                %{tag2} equals "ID3v2.3.0"

               Displays only files which have an ID3v2.3.0 tag.

           ID3v2.4.0 Tag
                %{tag2} equals "ID3v2.4.0"

               Displays only files which have an ID3v2.4.0 tag.

           Tag 1 != Tag 2
                not (%1{title} equals %2{title} and %1{album} equals %2{album} and %1{artist}
               equals %2{artist} and %1{comment} equals %2{comment} and %1{year} equals %2{year}
               and %1{track} equals %2{track} and %1{genre} equals %2{genre})

               Displays files with differences between tag 1 and tag2.

           Tag 1 == Tag 2
                %1{title} equals %2{title} and %1{album} equals %2{album} and %1{artist} equals
               %2{artist} and %1{comment} equals %2{comment} and %1{year} equals %2{year} and
               %1{track} equals %2{track} and %1{genre} equals %2{genre}

               Displays files with identical tag 1 and tag 2.

           Incomplete
                %{title} equals "" or %{artist} equals "" or %{album} equals "" or %{year} equals
               "" or %{tracknumber} equals "" or %{genre} equals ""

               Displays files with empty values in the standard tags (title, artist, album, date,
               track number, genre).

           No Picture
                %{picture} equals ""

               Displays only files which do not have a picture.

           Marked
                not (%{marked} equals "")

               Displays only files which are marked because they violate the ID3 standard, are
               truncated or the picture is too large.

           Custom Filter
               To add your own filter, select this entry. For instance, if you want to have a
               filter for artists starting with "The", replace "Custom Filter" with the name "The
               Bands" and press Enter. Then insert the following expression into the line edit:

                %{artist} matches "The.*"

               Then click Save Settings. Click Apply to filter the files. All files processed are
               displayed in the text view, with a "+" for those who match the filter and a "-"
               for the others. When finished, only the files with an artist starting with "The"
               are displayed, and the window title is marked with "[filtered]".

       Tools → Convert ID3v2.3 to ID3v2.4
           If there are any ID3v2.3 tags in the selected files, they will be converted to ID3v2.4
           tags. Frames which are not supported by TagLib will be discarded. Only files without
           unsaved changes will be converted.

       Tools → Convert ID3v2.4 to ID3v2.3
           If there are any ID3v2.4 tags in the selected files, they will be converted to ID3v2.3
           tags. Only files without unsaved changes will be converted.

       Tools → Play
           This opens a simple toolbar to play audio files. It contains buttons for the basic
           operations (Play/Pause, Stop playback, Previous Track, Next Track, Close), sliders for
           position and volume and a display of the current position. If multiple files are
           selected, the selected tracks are played, else all files will be played.

   The Settings Menu
       Settings → Show Toolbar
           Toggles displaying of the toolbar.

       Settings → Show Statusbar
           Toggles displaying of the statusbar, which displays longer actions such as opening or
           saving a directory.

       Settings → Show Picture
           Toggles displaying of the album cover art preview picture.

       Settings → Auto Hide Tags
           Empty tags are automatically hidden if this option is active. The File, Tag 1 and Tag
           2 sections can be manually collapsed and expanded by clicking on the corresponding -/+
           buttons.

       Settings → Configure Kid3...
           Opens the configuration dialog, which consists of pages for tags, files, user actions,
           and network settings.

           Tag specific options can be found on the Tags page, which is itself separated into
           four tabs for Tag 1, Tag 2, Tag 3, and All Tags.

           If Mark truncated fields is checked, truncated ID3v1.1 fields will be marked red. The
           text fields of ID3v1.1 tags can only have 30 characters, the comment only 28
           characters. Also the genre and track numbers are restricted, so that fields can be
           truncated when imported or transferred from ID3v2. Truncated fields and the file will
           be marked red, and the mark will be removed after the field has been edited.

           With Text encoding for ID3v1 it is possible to set the character set used in ID3v1
           tags. This encoding is supposed to be ISO-8859-1, so it is recommended to keep this
           default value. However, there are tags around with different encoding, so it can be
           set here and the ID3v1 tags can then be copied to ID3v2 which supports Unicode.

           The check box Use track/total number of tracks format controls whether the track
           number field of ID3v2 tags contains simply the track number or additionally the total
           number of tracks in the directory.

           When Genre as text instead of numeric string is checked, all ID3v2 genres will be
           stored as a text string even if there is a corresponding code for ID3v1 genres. If
           this option is not set, genres for which an ID3v1 code exists are stored as the number
           of the genre code (in parentheses for ID3v2.3). Thus the genre Metal is stored as
           "Metal" or "(9)" depending on this option. Genres which are not in the list of ID3v1
           genres are always stored as a text string. The purpose of this option is improved
           compatibility with devices which do not correctly interpret genre codes.

           When WAV files with lowercase id3 chunk is checked, the RIFF chunk used to store ID3v2
           tags in WAV files will be named "id3 " instead of "ID3 ". By default, Kid3 and other
           applications using TagLib accept both the lowercase and the uppercase variant when
           reading WAV files, but they use "ID3 " when writing ID3v2 tags to WAV files. As there
           exist other applications which only accept "id3 " (e.g. JRiver Media Center and
           foobar2000), this option can be used to create tags which can be read by such
           applications.

           When Mark standard violations is checked, ID3v2 fields which violate the standard will
           be marked red. Details about the violation are shown in a tooltip:

           ·   Must be unique

           ·   New line is forbidden

           ·   Carriage return is forbidden

           ·   Owner must be non-empty

           ·   Must be numeric

           ·   Must be numeric or number/total

           ·   Format is DDMM

           ·   Format is HHMM

           ·   Format is YYYY

           ·   Must begin with a year and a space character

           ·   Must be ISO 8601 date/time

           ·   Must be musical key, 3 characters, A-G, b, #, m, o

           ·   Must have ISO 639-2 language code, 3 lowercase characters

           ·   Must be ISRC code, 12 characters

           ·   Must be list of strings separated by '|'

           The ID3 standard documents are available online:

           ·   ID3 tag version 2.3.0[10]

           ·   ID3 tag version 2.4.0 - Main Structure[11]

           ·   ID3 tag version 2.4.0 - Native Frames[6]

           Text encoding defines the default encoding used for ID3v2 frames and can be set to
           ISO-8859-1, UTF16, or UTF8.  UTF8 is not valid for ID3v2.3.0 frames; if it is set,
           UTF16 will be used instead. For ID3v2.4.0 frames, all three encodings are possible.

           Version used for new tags determines whether new ID3v2 tags are created as version
           2.3.0 or 2.4.0.

           Track number digits is the number of digits in Track Number fields. Leading zeros are
           used to pad. For instance, with a value of 2 the track number 5 is set as "05".

           The combo box Comment field name is only relevant for Ogg/Vorbis and FLAC files and
           sets the name of the field used for comments. Different applications seem to use
           different names, "COMMENT" for instance is used by xmms, whereas amaroK uses
           "DESCRIPTION".

           The format of pictures in Ogg/Vorbis files is determined by Picture field name, which
           can be METADATA_BLOCK_PICTURE or COVERART. The first is the official standard and uses
           the same format as pictures in FLAC tags. COVERART is an earlier unofficial way to
           include pictures in Vorbis comments. It can be used for compatibility with legacy
           players.

           If the Mark if larger than check box is activated, files containing embedded album
           cover art exceeding the given size in bytes are marked red. This can be used to find
           files containing oversized pictures which are not accepted by some applications and
           players. The default value is 131072 bytes (128 KB).

           Custom Genres can be used to define genres which are not available in the standard
           genre list, e.g. "Gothic Metal". Such custom genres will appear in the Genre combo box
           of Tag 2. For ID3v1.1 tags, only the predefined genres can be used.

           The list of custom genres can also be used to reduce the number of genres available in
           the Genre combo box to those typically used. If your collection mostly contains music
           in the genres Metal, Gothic Metal, Ancient and Hard Rock, you can enter those genres
           and mark Show only custom genres. The Tag 2 Genre combo box will then only contain
           those four genres and you will not have to search through the complete genres list for
           them. In this example, only Metal and Hard Rock will be listed in the tag 1 genres
           list, because those two custom genres entries are standard genres. If Show only custom
           genres is not active, the custom genres can be found at the end of the genres list.

           Quick Access Frames defines which frame types are always shown in the Tag 2 section.
           Such frames can then be added without first using the Add button. The order of these
           quick access frames can be changed by dragging and dropping items.

           The combo box Track number field name is only relevant for RIFF INFO and sets the name
           of the field used for track numbers. Track numbers are not specified in the original
           RIFF standard, there are applications which use "ITRK", others use "IPRT".

           Tag Format contains options for the format of the tags. When Automatically apply
           format is checked, the format configuration is automatically used while editing text
           in the line edits.  Validation enables validators in the controls with track/total and
           date/time values. The Case conversion can be set to No changes, All lowercase, All
           uppercase, First letter uppercase or All first letters uppercase. To use locale-aware
           conversion between lowercase and uppercase characters, a locale can be selected in the
           combobox below. The string replacement list can be set to arbitrary string mappings.
           To add a new mapping, select the From cell of a row and insert the text to replace,
           then go to the To column and enter the replacement text. To remove a mapping set the
           From cell to an empty value (e.g. by first typing space and then backspace). Inserting
           and deleting rows is also possible using a context menu which appears when the right
           mouse button is clicked. Replacement is only active, if the String replacement
           checkbox is checked.

           The table in Rating contains the mapping of star ratings to the effective values
           stored in the tag. The frames with rating information are listed in the Rating row of
           the frame list. For these frames, the rating can be set by giving a number of stars
           out of five stars. Different tag formats and different applications use different
           values to map the star rating to the value stored in the tag. In order to display the
           correct number of stars, Kid3 will look up a map in this table. The key to look up the
           mapping is the frame name, for example "RATING" as used for Vorbis comments or "IRTD"
           for RIFF INFO. For ID3v2 tags, a combined key is used consisting of the frame ID
           "POPM" of the Popularimeter frame and its "Email" field, separated by a dot.
           Therefore, different keys for ID3v2 exist, e.g. "POPM.Windows Media Player 9 Series"
           for the mapping used by Windows Media Player and Explorer, and simply "POPM" for POPM
           frames with an empty "Email" field. As multiple entries for "POPM" can exist, their
           order is important. When Kid3 adds a new Popularimeter frame, it will use the first
           "POPM" entry to determine the value to be written into the "Email" field. This value
           will then specify the mapping to be used for star ratings. The first entry is also
           used if no key was found, it is therefore the default entry.

           Besides the Name column containing the keys, the table has columns 1 to 5 for the
           values to be stored when the corresponding number of stars is given. The other way
           round, the values determine the number of stars which are displayed for the value
           stored in the frame. For instance, the row in the table below contains the values 1,
           64, 128, 196, 255. The thresholds for the number of stars to be displayed lay between
           these values and are compatible with what the Windows Explorer uses.

           On the page Files the check box Load last-opened files can be marked so that Kid3 will
           open and select the last selected file when it is started the next time.  Preserve
           file timestamp can be checked to preserve the file modification time stamp.  Filename
           for cover sets the name which is suggested when an embedded image is exported to a
           file. With Text encoding (Export, Playlist) the encoding used when writing files can
           be set. The default System can be changed for example if playlists have to be used on
           a different device.

           If Mark changes is active, changed fields are marked with a light gray label
           background.

           The section File List determines which files are displayed in the file list. A Filter
           can be used to restrict the items in this list to files with supported extensions. To
           explicitly specify which directories to display in the file list or exclude certain
           directories, the options Include folders and Exclude folders can be used. They can
           contain wildcard expressions, for instance */Music/* to include only the Music folder,
           or */iTunes/* to exclude the iTunes folder from the file list. If multiple such
           expressions have to be used, they can be separated by spaces or semicolons.

           The buttons Filename from tag and Tag from filename in section Format open dialogs to
           edit the formats which are available in the Format combo boxes (with arrows up and
           down), which can be found in the File section of the main window.

           Filename Format contains options for the format of the filenames. The same options as
           in Tag Format are available.

           The User Actions page contains a table with the commands which are available in the
           context menu of the file list. For critical operations such as deleting files, it is
           advisable to mark Confirm to pop up a confirmation dialog before executing the
           command.  Output can be marked to see the output written by console commands (standard
           output and standard error).  Name is the name displayed in the context menu.  Command
           is the command line to be executed. Arguments can be passed using the following codes:

           ·   %F %{files} File paths (a list if multiple files selected)

           ·   %f %{file} File path to single file

           ·   %uF %{urls} URLs (a list if multiple files selected)

           ·   %uf %{url} URL to single file

           ·   %d %{directory} Directory

           ·   %s %{title} Title (Song)

           ·   %a %{artist} Artist

           ·   %l %{album} Album

           ·   %c %{comment} Comment

           ·   %y %{year} Year

           ·   %t %{track} Track (e.g. 01)

           ·   %t %{track.n} Track with field width n (e.g. 001 for %{track.3})

           ·   %T %{tracknumber} Track (without leading zeros, e.g. 1)

           ·   %g %{genre} Genre

           ·   %b %{browser} Command to start the web browser

           ·   %q %{qmlpath} Base directory of provided QML files

           The special code @separator can be set as a command to insert a separator into the
           user actions context menu. Menu items can be put into a submenu by enclosing them with
           @beginmenu and @endmenu commands. The name of the submenu is determined by the Name
           column of the @beginmenu command.

           To execute QML scripts, @qml is used as a command name. The path to the QML script is
           passed as a parameter. The provided scripts can be found in the folder
           %{qmlpath}/script/ (on Linux typically /usr/share/kid3/qml/script/, on Windows
           qml/script/ inside the installation directory, and on macOS in the app folder
           kid3.app/Contents/Resources/qml/script/). Custom scripts can be stored in any
           directory. If the QML code uses GUI components, @qmlview shall be used instead of
           @qml. Additional parameters are passed to the QML script where they will be available
           via the getArguments() function. An overview of some functions and properties which
           are available in QML can be found in the appendix QML Interface.

           The command which will be inserted with %{browser} can be defined in the Web browser
           line edit above. Commands starting with %{browser} can be used to fetch information
           about the audio files from the web, for instance

               %{browser} http://lyricwiki.org/%u{artist}:%u{title}

           will query the lyrics for the current song in LyricWiki[12]. The "u" in %u{artist} and
           %u{title} is used to URL-encode the artist %{artist} and song %{title} information. It
           is easy to define your own queries in the same way, e.g. an image search with
           Google[13]:

               %{browser} http://images.google.com/images?q=%u{artist}%20%u{album}

           To add album cover art to tag 2, you can search for images with Google or Amazon using
           the commands described above. The picture can be added to the tag with drag and drop.
           You can also add an image with Add, then select the Picture frame and import an image
           file or paste from the clipboard. Picture frames are supported for ID3v2, MP4, FLAC,
           Ogg and ASF tags.

           To add and delete entries in the table, a context menu can be used.

           The Network page contains only a field to insert the proxy address and optionally the
           port, separated by a colon. The proxy will be used when importing from an Internet
           server when the checkbox is checked.

           In the Plugins page, available plugins can be enabled or disabled. The plugins are
           separated into two sections. The Metadata Plugins & Priority list contains plugins
           which support audio file formats. The order of the plugins is important because they
           are tried from top to bottom. Some formats are supported by multiple plugins, so files
           will be opened with the first plugin supporting them. The TaglibMetadata supports most
           formats, if it is at the top of the list, it will open most of the files. If you want
           to use a different plugin for a file format, make sure that it is listed before the
           TaglibMetadata plugin. Details about the metadata plugin and why you may want to use
           them instead of TagLib are listed below.

           ·   Id3libMetadata: Uses id3lib[14] for ID3v1.1 and ID3v2.3 tags in MP3, MP2, AAC
               files. Supports a few more frame types than TagLib.

           ·   OggFlacMetadata: Uses libogg[15], libvorbis, libvorbisfile[16] for Ogg files, and
               additionally libFLAC++ and libFLAC[17] for FLAC files. These are the official
               libraries for these formats.

           ·   TaglibMetadata: Uses TagLib[18] which supports a lot of audio file formats. It can
               be used for all audio files supported by Kid3.

           ·   Mp4v2Metadata: mp4v2[19] was originally used by Kid3 to support M4A files. Can be
               used in case of problems with the M4A support of TagLib.

           The Available Plugins section lists the remaining plugins. Their order is not
           important, but they can be enabled or disabled using the check boxes.

           ·   AmazonImport: Used for the Import from Amazon...  function.

           ·   DiscogsImport: Used for the Import from Discogs...  function.

           ·   FreedbImport: Used for the Import from gnudb.org...  and Import from
               TrackType.org...  functions.

           ·   MusicBrainzImport: Used for the Import from MusicBrainz Release...  function.

           ·   AcoustidImport: Used for the Import from MusicBrainz Fingerprint...  function,
               which depends on the Chromaprint[20] and libav[21] libraries.

           Plugins which are disabled will not be loaded. This can be used to optimize resource
           usage and startup time. The settings on this page take only effect after a restart of
           Kid3.

       Settings → Configure Shortcuts...
           Opens a dialog to assign keyboard shortcuts for most of the program functions. There
           are even functions without corresponding menu or button available, e.g. next file,
           previous file, select all.

   The Help Menu
       Help → Kid3 Handbook
           Opens this handbook.

       Help → About Kid3
           Displays a short information about Kid3.

KID3-CLI

   Commands
       kid3-cli offers a command-line-interface for Kid3. If a directory path is used, the
       directory is opened. If one or more file paths are given, the common directory is opened
       and the files are selected. Subsequent commands will then work on these files. Commands
       are specified using -c options. If multiple commands are passed, they are executed in the
       given order. If files are modified by the commands, they will be saved at the end. If no
       command options are passed, kid3-cli starts in interactive mode. Commands can be entered
       and will operate on the current selection. The following sections list all available
       commands.

       Help
           help [COMMAND-NAME]

           Displays help about the parameters of COMMAND-NAME or about all commands if no command
           name is given.

       Timeout
           timeout [default | off | TIME]

           Overwrite the default command timeout. The CLI commands abort after a command specific
           timeout is expired. This timeout is 10 seconds for ls and albumart, 60 seconds for
           autoimport and filter, and 3 seconds for all other commands. If a huge number of files
           has to be processed, this timeouts may be too restrictive, thus the timeout for all
           commands can be set to TIME ms, switched off altogether or be left at the default
           values.

       Quit application
           exit [force]

           Exit application. If there are modified unsaved files, the force parameter is
           required.

       Change directory
           cd [DIRECTORY]

           If no DIRECTORY is given, change to the home directory. If a directory is given,
           change into the directory. If one or more file paths are given, change to their common
           directory and select the files.

       Print the current working directory
           pwd

           Print the filename of the current working directory.

       Directory list
           ls

           List the contents of the current directory. This corresponds to the file list in the
           Kid3 GUI. Five characters before the file names show the state of the file.

           ·   > File is selected.

           ·   * File is modified.

           ·   1 File has a tag 1, otherwise '-' is displayed.

           ·   2 File has a tag 2, otherwise '-' is displayed.

           ·   3 File has a tag 3, otherwise '-' is displayed.

           In this example, all files have a tag 1, the second file also has a tag 2 and it is
           selected. The third file is modified.

       Save the changed files
           save

       Select file
           select [all | none | first | previous | next | FILE...]

           To select all files, enter select all, to deselect all files, enter select none. To
           traverse the files in the current directory start with select first, then go forward
           using select next or backward using select previous. Specific files can be added to
           the current selection by giving their file names. Wildcards are possible, so select
           *.mp3 will select all MP3 files in the current directory.

               >*1-- 03 Outro.mp3

       Select tag
           tag [TAG-NUMBERS]

           Many commands have an optional TAG-NUMBERS parameter, which specifies whether the
           command operates on tag 1, 2, or 3. If this parameter is omitted, the default tag
           numbers are used, which can be set by this command. At startup, it is set to 12 which
           means that information is read from tag 2 if available, else from tag 1; modifications
           are done on tag 2. The TAG-NUMBERS can be set to 1, 2, or 3 to operate only on the
           corresponding tag. If the parameter is omitted, the current setting is displayed.

       Get tag frame
           get [all | FRAME-NAME] [TAG-NUMBERS]

           This command can be used to read the value of a specific tag frame or get information
           about all tag frames (if the argument is omitted or all is used). Modified frames are
           marked with a '*'.

           To save synchronized lyrics to an LRC file, use

               get SYLT:'/path/to/lyrics.lrc'

           It is possible to get only a specific field from a frame, for example get POPM.Email
           for the Email field of a Popularimeter frame. If a file has multiple frames of the
           same kind, the different frames can be indexed with brackets, for example the first
           performer from a Vorbis comment can be retrieved using get performer[0], the second
           using get performer[1].

           The pseudo field name "selected" can be used to check if a frame is selected, for
           example get artist.selected will return 1 if the artist frame is selected, else 0.

       Set tag frame
           set {FRAME-NAME} {FRAME-VALUE} [TAG-NUMBERS]

           This command sets the value of a specific tag frame. If FRAME-VALUE is empty, the
           frame is deleted.

               kid3-cli> set remixer 'O.H. Wonder'

           To set the contents of a picture frame from a file, use

               set picture:'/path/to/folder.jpg' 'Picture Description'

           To set synchronized lyrics from an LRC file, use

               set SYLT:'/path/to/lyrics.lrc' 'Lyrics Description'

           To set a specific field of a frame, the field name can be given after a dot, e.g. to
           set the Counter field of a Popularimeter frame, use

               set POPM.Counter 5

           An application for field specifications is the case where you want a custom TXXX frame
           with "rating" description instead of a standard Popularimeter frame (this seems to be
           used by some plugins). You can create such a TXXX rating frame with kid3-cli, however,
           you have to first create a TXXX frame with description "rating" and then set the value
           of this frame to the rating value.

               kid3-cli> set rating ""
               kid3-cli> set TXXX.Description rating
               kid3-cli> set rating 5

           The first command will delete an existing POPM frame, because if such a frame exists,
           set rating 5 would set the POPM frame and not the TXXX frame. Another possibility
           would be to use set TXXX.Text 5, but this would only work if there is no other TXXX
           frame present.

           To set multiple frames of the same kind, an index can be given in brackets, e.g. to
           set multiple performers in a Vorbis comment, use

               kid3-cli> set performer[0] 'Liza don Getti (soprano)'
               kid3-cli> set performer[1] 'Joe Barr (piano)'

           To select certain frames before a copy, paste or remove action, the pseudo field name
           "selected" can be used. Normally, all frames are selected, to deselect all, use set
           '*.selected' 0, then for example set artist.selected 1 to select the artist frame.

       Revert
           revert

           Revert all modifications in the selected files (or all files if no files are
           selected).

       Import from file or clipboard
           import {FILE} {FORMAT-NAME} [TAG-NUMBERS]

           Tags are imported from the file FILE (or from the clipboard if clipboard is used for
           FILE) in the format with the name FORMAT-NAME (e.g.  "CSV unquoted", see Import).

           If tags is given for FILE, tags are imported from other tags. Instead of FORMAT-NAME
           parameters SOURCE and EXTRACTION are required, see Import from Tags.

       Automatic import
           autoimport [PROFILE-NAME] [TAG-NUMBERS]

           Batch import using profile PROFILE-NAME (see Automatic Import, "All" is used if
           omitted).

       Download album cover artwork
           albumart {URL} [all]

           Set the album artwork by downloading a picture from URL. The rules defined in the
           Browse Cover Art dialog are used to transform general URLs (e.g. from Amazon) to a
           picture URL. To set the album cover from a local picture file, use the set command.

               kid3-cli> albumart
               http://www.amazon.com/Versus-World-Amon-Amarth/dp/B000078DOC

       Export to file or clipboard
           export {FILE} {FORMAT-NAME} [TAG-NUMBERS]

           Tags are exported to file FILE (or to the clipboard if clipboard is used for FILE) in
           the format with the name FORMAT-NAME (e.g.  "CSV unquoted", see Export).

       Create playlist
           playlist

           Create playlist in the format set in the configuration, see Create Playlist.

       Apply filename format
           filenameformat

           Apply file name format set in the configuration, see Apply Filename Format.

       Apply tag format
           tagformat

           Apply tag name format set in the configuration, see Apply Tag Format.

       Apply text encoding
           textencoding

           Apply text encoding set in the configuration, see Apply Text Encoding.

       Rename directory
           renamedir [FORMAT] [create | rename | dryrun] [TAG-NUMBERS]

           Rename or create directories from the values in the tags according to a given FORMAT
           (e.g.  %{artist} - %{album}, see Rename Directory), if no format is given, the format
           defined in the Rename directory dialog is used. The default mode is rename; to create
           directories, create must be given explicitly. The rename actions will be performed
           immediately, to just see what would be done, use the dryrun option.

       Number tracks
           numbertracks [TRACK-NUMBER] [TAG-NUMBERS]

           Number the selected tracks starting with TRACK-NUMBER (1 if omitted).

       Filter
           filter [FILTER-NAME | FILTER-FORMAT]

           Filter the files so that only the files matching the FILTER-FORMAT are visible. The
           name of a predefined filter expression (e.g.  "Filename Tag Mismatch") can be used
           instead of a filter expression, see Filter.

           to24

       Convert ID3v2.4 to ID3v2.3
           to23

       Filename from tag
           fromtag [FORMAT] [TAG-NUMBERS]

           Set the file names of the selected files from values in the tags, for example fromtag
           '%{track} - %{title}' 1. If no format is specified, the format set in the GUI is used.

       Tag from filename
           totag [FORMAT] [TAG-NUMBERS]

           Set the tag frames from the file names, for example totag '%{albumartist} -
           %{album}/%{track} %{title}' 2. If no format is specified, the format set in the GUI is
           used. If the format of the filename does not match this pattern, a few other commonly
           used formats are tried.

       Tag to other tag
           syncto {TAG-NUMBER}

           Copy the tag frames from one tag to the other tag, e.g. to set the ID3v2 tag from the
           ID3v1 tag, use syncto 2.

       Copy
           copy [TAG-NUMBER]

           Copy the tag frames of the selected file to the internal copy buffer. They can then be
           set on another file using the paste command.

           To copy only a subset of the frames, use the "selected" pseudo field with the set
           command. For example, to copy only the disc number and copyright frames, use

               set '*.selected' 0
               set discnumber.selected 1
               set copyright.selected 1
               copy

       Paste
           paste [TAG-NUMBER]

           Set tag frames from the contents of the copy buffer in the selected files.

       Remove
           remove [TAG-NUMBER]

           Remove a tag.

           It is possible to remove only a subset of the frames by selecting them as described in
           the copy command.

       Play
           play [pause | stop | previous | next]

           Start audio playback. Once it has been started, it can be controlled with the pause
           (to pause and resume), stop, previous and next options.

   Examples
       Set title containing an apostrophe. Commands passed to kid3-cli with -c have to be in
       quotes if they do not only consist of a single word. If such a command itself has an
       argument containing spaces, that argument has to be quoted too. In UNIX shells single or
       double quotes can be used, but on the Windows Command Prompt, it is important that the
       outer quoting is done using double quotes and inside these quotes, single quotes are used.
       If the text inside the single quotes contains a single quote, it has to be escaped using a
       backslash character, as shown in the following example:

           kid3-cli -c "set title 'I\'ll be there for you'" /path/to/dir

       Set album cover in all files of a directory using the batch import function:

           kid3-cli -c "autoimport 'Cover Art'" /path/to/dir

       Remove comment frames and apply the tag format in both tags of all MP3 files of a
       directory:

           kid3-cli -c "set comment '' 1" -c "set comment '' 2" \
           -c "tagformat 1" -c "tagformat 2" /path/to/dir/*.mp3

       Automatically import tag 2, synchronize to tag 1, set file names from tag 2 and finally
       create a playlist:

           kid3-cli -c autoimport -c "syncto 1" -c fromtag -c playlist \
             /path/to/dir/*.mp3

       For all files with an ID3v2.4.0 tag, convert to ID3v2.3.0 and remove the arranger frame:

           kid3-cli -c "filter 'ID3v2.4.0 Tag'" -c "select all" -c to23 \
             -c "set arranger ''" /path/to/dir

       This Python script uses kid3-cli to generate iTunes Sound Check iTunNORM frames from
       replay gain information.

           #!/usr/bin/env python3
           # Generate iTunes Sound Check from ReplayGain.
           import os, sys, subprocess

           def rg2sc(dirpath):
             for root, dirs, files in os.walk(dirpath):
               for name in files:
                 if name.endswith(('.mp3', '.m4a', '.aiff', '.aif')):
                   fn = os.path.join(root, name)
                   rg = subprocess.check_output([
                     'kid3-cli', '-c', 'get "replaygain_track_gain"',
                      fn]).strip()
                   if rg.endswith(b' dB'):
                     rg = rg[:-3]

INSTALLATION

   How to obtain Kid3
       Kid3 can be found at https://kid3.sourceforge.io.

   Requirements
       Kid3 needs Qt[24].  KDE[25] is recommended but not necessary, as Kid3 can also be compiled
       as a Qt application.  Kid3 can be compiled for systems where these libraries are
       available, e.g. for GNU/Linux, Windows and macOS. To tag Ogg/Vorbis files, libogg[15],
       libvorbis and libvorbisfile[16] are required, for FLAC files libFLAC++ and libFLAC[17].
       id3lib[14] is used for MP3 files. These four formats are also supported by TagLib[18],
       which can also handle Opus, MPC, APE, MP2, Speex, TrueAudio, WavPack, WMA, WAV, AIFF files
       and tracker modules. To import from acoustic fingerprints, Chromaprint[20] and libav[21]
       are used.

       Kid3 is available for most Linux distributions, Windows and macOS. Links can be found on
       https://kid3.sourceforge.io.

   Compilation and Installation
       You can compile Kid3 with or without KDE. Without KDE, Kid3 is a simple Qt application and
       lacks some configuration and session features.

       For a KDE version, go into the top directory and type

           % cmake .
           % make
           % make install

       To compile for different versions of Qt or KDE, set the corresponding cmake options.

       If not all libraries are present, Kid3 is built with reduced functionality. So you should
       take care to have all desired development packages installed. On the other side,
       cmake-options control which libraries are compiled in. The default is
       -DWITH_TAGLIB:BOOL=ON -DWITH_MP4V2:BOOL=OFF -DWITH_ID3LIB:BOOL=ON
       -DWITH_CHROMAPRINT:BOOL=ON -DWITH_VORBIS:BOOL=ON -DWITH_FLAC:BOOL=ON . These options can
       be disabled using OFF.

       To build Kid3 as a Qt application without KDE, use the cmake option -DWITH_APPS=Qt. To
       build both a KDE and a Qt application, set -DWITH_APPS="Qt;KDE".

       To use a specific Qt installation, set -DQT_QMAKE_EXECUTABLE=/path/to/qmake.

       Generation of RPM-Packages is supported by the file kid3.spec, for Debian-Packages, the
       script build-deb.sh is available.

       The Qt application can also be compiled for Windows and macOS. The script buildlibs.sh can
       be used to download and build all required libraries and create a Kid3 package.

   Configuration
       With KDE, the settings are stored in .config/kid3rc. As a Qt application, this file is in
       .config/Kid3/Kid3.conf. On Windows, the configuration is stored in the registry. on macOS
       in a plist file.

       The environment variable KID3_CONFIG_FILE can be used to set the path of the configuration
       file.

D-BUS INTERFACE

   D-Bus Examples
       On Linux a D-Bus-interface can be used to control Kid3 by scripts. Scripts can be written
       in any language with D-Bus-bindings (e.g. in Python) and can be added to the User Actions
       to extend the functionality of Kid3.

       The artist in tag 2 of the current file can be set to the value "One Hit Wonder" with the
       following code:

       Shell

               dbus-send --dest=net.sourceforge.kid3 --print-reply=literal \
               /Kid3 net.sourceforge.Kid3.setFrame int32:2 string:'Artist' \
               string:'One Hit Wonder'

           or easier with Qt's qdbus (qdbusviewer can be used to explore the interface in a GUI):

               qdbus net.sourceforge.kid3 /Kid3 setFrame 2 Artist \
               'One Hit Wonder'

       Python

               import dbus
               kid3 = dbus.SessionBus().get_object(
                 'net.sourceforge.kid3', '/Kid3')
               kid3.setFrame(2, 'Artist', 'One Hit Wonder')

       Perl

               use Net::DBus;
               $kid3 = Net::DBus->session->get_service(
                 "net.sourceforge.kid3")->get_object(
                 "/Kid3", "net.sourceforge.Kid3");
               $kid3->setFrame(2, "Artist", "One Hit Wonder");

QML INTERFACE

   QML Examples
       QML scripts can be invoked via the context menu of the file list and can be set in the tab
       User Actions of the settings dialog. The scripts which are set there can be used as
       examples to program custom scripts. QML uses JavaScript, here is the obligatory "Hello
       World":

           import Kid3 1.0

           Kid3Script {
             onRun: {
               console.log("Hello world, directory is", app.dirName)
               Qt.quit()
             }
           }

       If this script is saved as /path/to/Example.qml, the user command can be defined as @qml
       /path/to/Example.qml with name QML Test and Output checked. It can then be started using
       the QML Test item in the file list context menu, and the output will be visible in the
       window.

       Alternatively, the script could also be started independent of Kid3 using the QML tools.

           qml -apptype widget -I /usr/lib/kid3/plugins/imports /path/to/Example.qml

       or

           qmlscene -I /usr/lib/kid3/plugins/imports /path/to/Example.qml

       On Windows and macOS, the import path must be adapted to the imports folder inside the
       installation directory. Scripts started outside of Kid3 will use the current directory, so
       it should be changed beforehand.

       To list the titles in the tags 2 of all files in the current directory, the following
       script could be used:

           import Kid3 1.0

           Kid3Script {
             onRun: {
               app.firstFile()
               do {
                 if (app.selectionInfo.tag(Frame.Tag_2).tagFormat) {
                   console.log(app.getFrame(tagv2, "title"))
                 }
               } while (app.nextFile())
             }
           }

       If the directory contains many files, such a script might block the user interface for
       some time. For longer operations, it should therefore have a break from time to time. The
       alternative implementation below has the work for a single file moved out into a function.
       This function invokes itself with a timeout of 1 ms at the end, given that more files have
       to be processed. This will ensure that the GUI remains responsive while the script is
       running.

           import Kid3 1.0

           Kid3Script {
             onRun: {
               function doWork() {
                 if (app.selectionInfo.tag(Frame.Tag_2).tagFormat) {
                   console.log(app.getFrame(tagv2, "title"))
                 }
                 if (!app.nextFile()) {
                   Qt.quit()
                 } else {
                   setTimeout(doWork, 1)
                 }
               }

               app.firstFile()
               doWork()
             }
           }

       When using app.firstFile() with app.nextFile(), all files of the current directory will be
       processed. If only the selected files shall be affected, use firstFile() and nextFile()
       instead, these are convenience functions of the Kid3Script component. The following
       example is a script which copies only the disc number and copyright frames of the selected
       file.

           import Kid3 1.1

           Kid3Script {
             onRun: {
               function doWork() {
                 if (app.selectionInfo.tag(Frame.Tag_2).tagFormat) {
                   app.setFrame(tagv2, "*.selected", false)
                   app.setFrame(tagv2, "discnumber.selected", true)
                   app.setFrame(tagv2, "copyright.selected", true)
                   app.copyTags(tagv2)
                 }
                 if (!nextFile()) {
                   Qt.quit()
                 } else {
                   setTimeout(doWork, 1)
                 }
               }

               firstFile()
               doWork()
             }
           }

   QML API
       The API can be easily explored using the QML Console, which is available as an example
       script with a user interface.

       Kid3Script
           Kid3Script is a regular QML component located inside the plugin directory. You could
           use another QML component just as well. Using Kid3Script makes it easy to start the
           script function using the onRun signal handler. Moreover it offers some functions:

               onRun: Signal handler which is invoked when the script is started
               tagv1, tagv2, tagv2v1: Constants for tag parameters
               script: Access to scripting functions
               configs: Access to configuration objects
               getArguments(): List of script arguments
               isStandalone(): true if the script was not started from within Kid3
               setTimeout(callback, delay): Starts callback after delay ms
               firstFile(): To first selected file
               nextFile(): To next selected file

       Scripting Functions
           As JavaScript and therefore QML too has only a limited set of functions for scripting,
           the script object has some additional methods, for instance:

               script.properties(obj): String with Qt properties
               script.writeFile(filePath, data): Write data to file, true if OK
               script.readFile(filePath): Read data from file
               script.removeFile(filePath): Delete file, true if OK
               script.fileExists(filePath): true if file exists

                 [exit code, standard output, standard error] if not timeout
               script.systemAsync(program, [args], [callback]): Asynchronously start a system
               command, callback will be called with [exit code, standard output, standard
               error]
               script.getEnv(varName): Get value of environment variable
               script.setEnv(varName, value): Set value of environment variable
               script.getQtVersion(): Qt version string, e.g. "5.4.1"

               script.saveImage(img, filePath, [format]): Save an image to a file, true if OK
               script.imageProperties(img): Get properties of an image, map containing
                 "width", "height", "depth" and "colorCount", empty if invalid image
               script.scaleImage(img, width, [height]): Scale an image, returns scaled image

       Application Context
           Using QML, a large part of the Kid3 functions are accessible. The API is similar to
           the one used for D-Bus. For details, refer to the respective notes.

               }

       Configuration Objects
           The different configuration sections are accessible via methods of configs. Their
           properties can be listed in the QML console.

               script.properties(configs.networkConfig())

           Properties can be set:

               configs.networkConfig().useProxy = false

               configs.batchImportConfig()
