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], MusicBrainz[2],
Discogs[3], Amazon[4] 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 folder
containing MP3 files with the tracks from the album "Let's Tag" from the band "One Hit
Wonder". The folder is named in the "artist - album" format, in our case One Hit Wonder -
Let's Tag. The folder 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 folder name and does not have to be
repeated in the filename. But back to our example, the folder 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 File → Open
menu item (or toolbar button) and select one of the files in this folder. All files will
be displayed in the file listbox. Lazy as we are, we want to use the information in the
folder 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 check boxes are automatically checked and all other check boxes
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 File → Save
menu item (or toolbar button). Selecting File → Create Playlist menu item (or toolbar
button) will generate a file One Hit Wonder - Let's Tag.m3u in the folder.
COMMAND REFERENCE
The GUI Elements
The Kid3 GUI is separated in six sections: At the left are the file and folder listboxes,
the right side contains the File, Tag 1, Tag 2 and Tag 3 sections.
To navigate between the different sections using the keyboard, several keyboard shortcuts
are supported. In the tag sections, the shortcuts are active while not editing text or
when being in the first column.
• Alt+Left: Go to previous section (Command+[ on macOS®)
• Alt+Right: Go to next section (Command+] on macOS®)
• Ctrl+Shift+V: From other tag
• Ctrl+C: Copy
• Ctrl+V: Paste
• Shift+Delete: Remove
• F2: Edit
• Insert: Add
• Delete: Delete
File List
The file list contains the names of all the files in the opened folder 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.
The values of the standard tags can also be displayed and edited in columns of the
file list.
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).
Folders are displayed with a folder icon. If a folder is opened, its files are
displayed in a hierarchical tree. By selecting files from subfolders, operations can
be executed on files in different folders, 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.
When Select file on play is activated, the currently played track is automatically
selected in the file list.
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.
Folder List
The folder list contains the names of the folders in the opened folder, as well as the
current (.) and the parent (..) folder. It allows one to quickly change the folder
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 folder part separated by a slash from the file name, but that
folder 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 check box 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 check
box 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 cannot 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 ID3v1 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[5] 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[6]. 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.
Chapters in MP4 Files
MP4 audiobooks typically have a .m4b extension and are rather large because they
contain all chapters in a single file. To navigate in such files, they can contain
chapter marks, which can be edited in Kid3 in a pseudo "Chapters" frame using the same
editor which is used for synchronized lyrics. Note, however, that this feature is only
available with the Mp4v2Metadata plugin, so make sure that it is activated and above
the TaglibMetadata plugin in the Plugins tab of the settings if you have to edit MP4
chapters.

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 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[7] 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.
If you already have a search result open in the web browser, you can enter the URL
into the first search field. The result will then appear in the album list and can be
directly imported into Kid3.
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. A
Token can be entered to use the RESTful Discogs API instead of their web interface,
which is often changed, thereby breaking the import parser. You have to register for
an account on Discogs[8] and then generate a token on their web site
(Settings/Developers, Generate new token). Don't forget to Save Settings after
entering the token in order to use it in subsequent requests too. 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 folder. The
destination (Tag 1, Tag 2 or Tag 1 and Tag 2) can be selected with a combo box. The
files in the current folder 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(TM), 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 folder. 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 check box Check maximum allowable time difference (sec): 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 option with the
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 check boxes 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
button 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.
Import from Tags... is also directly available from the File menu. The difference
between these two functions is that the import dialog subdialog operates on all files
of the current folder whereas the menu function operates on the selected files (which
can be in different folders). The menu function supports an additional code
"%{__return}" to return the extracted value, which can be useful with the CLI and QML
interfaces.
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 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 → Import from Tags...
Like From Tags, but the import is applied to the selected files.
File → Automatic Import...
Automatic Import allows one to import information for multiple albums from various web
services. If folders are selected in the file list, track data for the selected
folders will be imported. If no folder is selected, all folders 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 folder 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
• %{modificationdate} Modification date
• %{creationdate} Creation date
• %u %{url} URL
• %{dirname} Folder 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 folder. 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 folder 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. The list of available
formats can be edited in the Format section of the Files tab in the settings. 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 folder
The playlist is created in the current folder and contains only files of the
current folder. The current folder is the folder where the current file is
located. If multiple files are selected, the current file is probably the last
selected file.
Every folder
A playlist is created in every folder which contains listed files, and each
playlist contains the files of that folder.
Top-level folder
Only one playlist is created in the top-level folder (i.e. the folder of the file
list) and it contains the listed files of the top-level folder and all of its
sub-folders.
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 folder 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 Folder
Selects all files of the current folder.
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 check box 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 section → Tag 2
tab 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 Folder...
This dialog offers the possibility to automatically rename the currently open folder
according to the tags in the files. Several formats are preconfigured to include
information about artist, album and year in the folder 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 folder 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} Folder name (e.g. %{year" "}%{dirname} will prepend the year to the
current folder name)
• %{max-year} The maximum year value found for this folder, can also be used with
other codes than "year"
• %{min-year} The minimum year value found for this folder
• %{unq-year} The unique year value found for this folder or empty if not unique
If a folder separator "/" is found in the format, multiple folders are created. If you
want to create a new folder instead of renaming the current folder, in the Action
combo box select Create Folder instead of Rename Folder. The Source of the tag
information can be chosen between Tag 1 and Tag 2, Tag 1 and 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 folders 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 folders. The folders have to be
expanded and selected.
If Reset counter for each folder is checked, track numbering is restarted with the
given number for each folder 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 time displayed can be toggled between elapsed and remaining time by clicking on
the display.
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 folder.
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 Shortcut keys...
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.
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 folder.
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 '|'
• Has excess white space
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[5]
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 (bytes) 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.
In Custom Frames, up to eight custom frame names can be defined, which can then be
used like the unified frames, for example as quick access frames.
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. When the text to replace
starts and ends with a slash ("/"), a regular expression is used. For regular
expressions containing capturing groups, occurrences of \1, \2, ... in To are replaced
with the string captured by the corresponding capturing group. 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 check box 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.
Table 1. Entry in Rating Table

└──────┴──────┴───────┴────────┴─────────┴─────────┘
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 folders to display in the file list or exclude certain
folders, 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.
The Playlist button can be used to edit the file name formats available in the Create
Playlist dialog.
Filename Format contains options for the format of the filenames. The same options as
in Tag Format are available.
Additionally, the Maximum length allowed for file names can be set. Most modern file
systems have a limit of 255 characters, but if you want to burn the files to CD, you
should set the limit to 64. If Use for playlist and folder names is checked, the file
name format is also used when creating playlists and renaming folders.
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} Folder
• %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 folder 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 folder, and on macOS® in the app folder
kid3.app/Contents/Resources/qml/script/). Custom scripts can be stored in any folder.
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 check box 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... function.
• 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.

KID3-CLI
Commands
kid3-cli offers a command-line-interface for Kid3. If a folder path is used, the folder is
opened. If one or more file paths are given, the common folder 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, these 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 folder
cd [FOLDER]
If no FOLDER is given, change to the home folder. If a folder is given, change into
the folder. If one or more file paths are given, change to their common folder and
select the files.
Print the filename of the current folder
pwd
Print the filename of the current working folder.
Folder list
ls
List the contents of the current folder. 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.
kid3-cli> ls
1-- 01 Intro.mp3
> 12- 02 We Only Got This One.mp3
*1-- 03 Outro.mp3
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 folder 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 folder.
kid3-cli> select first
kid3-cli> ls
> 1-- 01 Intro.mp3
12- 02 We Only Got This One.mp3
*1-- 03 Outro.mp3
kid3-cli> select next
kid3-cli> ls
1-- 01 Intro.mp3
> 12- 02 We Only Got This One.mp3
*1-- 03 Outro.mp3
kid3-cli> select *.mp3
kid3-cli> ls
> 1-- 01 Intro.mp3
> 12- 02 We Only Got This One.mp3
>*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 '*'.
kid3-cli> get
File: MPEG 1 Layer 3 192 kbps 44100 Hz Joint Stereo
Name: 01 Intro.mp3
Tag 1: ID3v1.1
Title Intro

Album Let's Tag
Date 2013
Track Number 1
Genre Pop
kid3-cli> get title
Intro
To save the contents of a picture frame to a file, use
get picture:'/path/to/folder.jpg'
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.
The pseudo frame name "ratingstars" can be used to get the value of the "rating" frame
as the format specific value corresponding to the number of stars (0 to 5). When using
"rating", the internal value is returned.
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.
The pseudo frame name "ratingstars" can be used to set the value of the "rating" frame
to the format specific value corresponding to the number of stars (0 to 5). The frame
name "rating" can be used to set the internal value.
Setting "ratingstars" on multiple files having different tag formats will not work
because the frame with the value mapped from the star count is created for the first
file and then used for all files. So instead of kid3-cli -c "set ratingstars 2" * you
should rather use for f in *; do kid3-cli -c "set ratingstars 2" "$f"; done.
Revert
revert
Revert all modifications in the selected files (or all files if no files are
selected).
Import from file
import {FILE} {FORMAT-NAME} [TAG-NUMBERS]
Tags are imported from the file 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. To apply the
import from tags on the selected files, use tagsel instead of tags. This function also
supports output of the extracted value by using an EXTRACTION with the value
%{__return}(.+).
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
export {FILE} {FORMAT-NAME} [TAG-NUMBERS]
Tags are exported to file FILE in the format with the name FORMAT-NAME (e.g. "CSV
unquoted", see Export).
Create playlist

Rename folder
renamedir [FORMAT] [create | rename | dryrun] [TAG-NUMBERS]
Rename or create folders from the values in the tags according to a given FORMAT (e.g.
%{artist} - %{album}, see Rename Folder), if no format is given, the format defined in
the Rename folder dialog is used. The default mode is rename; to create folders,
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.
kid3-cli> filter '%{title} contains "tro"'

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.
Configure Kid3
config [OPTION] [VALUE]
Query or set a configuration option.
The OPTION consists of a group name and a property name separated by a dot. When no
OPTION is given, all available groups are displayed. If only a group name is given,
all available properties of the group are displayed. For a given group and property,
the currently configured value is displayed. To change the setting, the new value can
be passed as a second argument.
If the value of a setting is a list, all list elements have to be given as arguments.
This means that to append an element to an existing list of elements, all existing
elements have to be passed followed by the new element. In such a situation, it is
easier to use the JSON mode, where the current list can be copied with the new element
appended.
Execute program or QML script
execute [@qml] {FILE} [ARGS]
Execute a QML script or an executable.
Without @qml a program is executed with arguments. When @qml is given as the first
argument, the following arguments are the QML script and its arguments. For example,
the tags of a folder can be exported to the file export.csv with the following
command.
kid3-cli -c "execute @qml
/usr/share/kid3/qml/script/ExportCsv.qml export.csv"
/path/to/folder/
Here export.csv is the argument for the ExportCsv.qml script, whereas /path/to/folder/
is the FILE argument for kid3-cli.
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/folder
Set album cover in all files of a folder using the batch import function:
kid3-cli -c "autoimport 'Cover Art'" /path/to/folder
Remove comment frames and apply the tag format in both tags of all MP3 files of a folder:
kid3-cli -c "set comment '' 1" -c "set comment '' 2" \
-c "tagformat 1" -c "tagformat 2" /path/to/folder/*.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/folder/*.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/folder
This Python script uses kid3-cli to generate iTunes Sound Check iTunNORM frames from
replay gain information.

JSON Format
In order to make it easier to parse results from kid3-cli, it is possible to get the
output in JSON format. When the request is in JSON format, the response will also be JSON.
A compact format of the request will also give a compact representation of the response.
If the request contains an "id" field, it is assumed to be a JSON-RPC request and the
response will contain a "jsonrpc" field and the "id" of the request. The request format
uses the same commands as the standard CLI, the "method" field contains the command and
the parameters (if any) are given in the "params" list. The response contains a "result"
object, which can also be null if the corresponding kid3-cli command does not return a
result. In case of an error, an "error" object is returned with "code" and "message"
fields as used in JSON-RPC.
kid3-cli> {"method":"set","params":["artist","An Artist"]}
{"result":null}
kid3-cli> {"method":"get","params":["artist",2]}
{"result":"An Artist"}
kid3-cli> {"method": "get", "params": ["artist"]}

compiled as a Qt(TM) 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.kde.org.
Compilation and Installation
You can compile Kid3 with or without KDE. Without KDE, Kid3 is a simple Qt(TM) application
and lacks some configuration and session features.
For a KDE version, go into the top folder and type
% cmake .
% make
% make install
To compile for different versions of Qt(TM) 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(TM) application without KDE, use the cmake option -DWITH_APPS=Qt. To
build both a KDE and a Qt(TM) application, set -DWITH_APPS="Qt;KDE".
To use a specific Qt(TM) installation, set -DQT_QMAKE_EXECUTABLE=/path/to/qmake.
Generation of RPM-Packages is supported by the file kid3.spec, for Debian® Packages, run
build.sh deb.
The Qt(TM) application can also be compiled for Windows® and macOS®. The script build.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, the application state in
.local/share/kid3/kid3staterc. As a Qt(TM) 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=org.kde.kid3 --print-reply=literal \
/Kid3 org.kde.Kid3.setFrame int32:2 string:'Artist' \
string:'One Hit Wonder'
or easier with Qt(TM)'s qdbus (qdbusviewer can be used to explore the interface in a
GUI):
qdbus org.kde.kid3 /Kid3 setFrame 2 Artist \
'One Hit Wonder'
Python
import dbus
kid3 = dbus.SessionBus().get_object(
'org.kde.kid3', '/Kid3')
kid3.setFrame(2, 'Artist', 'One Hit Wonder')
Perl
use Net::DBus;
$kid3 = Net::DBus->session->get_service(
"org.kde.kid3")->get_object(
"/Kid3", "org.kde.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, folder 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.
Unfortunately, starting the QML scripts using the qml (e.g. qml -apptype widget -I
/usr/lib/kid3/plugins/imports /path/to/Example.qml) is broken in recent versions of Qt.
But kid3-cli offers an alternative way to run a QML script from the command line using its
execute command.
kid3-cli -c "execute @qml /path/to/Example.qml"
To list the titles in the tags 2 of all files in the current folder, 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 folder 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 folder 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 folder. 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

script.getFilePermissions(filePath): Get file permission mode bits
script.setFilePermissions(filePath, modeBits): Set file permission mode bits
script.classifyFile(filePath): Get class of file (folder "/", symlink "@", exe "*",
file " ")
script.renameFile(oldName, newName): Rename file, true if OK
script.copyFile(source, dest): Copy file, true if OK
script.makeDir(path): Create folder, true if OK
script.removeDir(path): Remove folder, true if OK
script.tempPath(): Path to temporary folder
script.musicPath(): Path to music folder
script.listDir(path, [nameFilters], [classify]): List folder entries
script.system(program, [args], [msecs]): Synchronously start a system command,
[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.getDataMd5(data): Get hex string of the MD5 hash of data
script.getDataSize(data): Get size of byte array
script.dataToImage(data, [format]): Create an image from data bytes
script.dataFromImage(img, [format]): Get data bytes from image
script.loadImage(filePath): Load an image from a file
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
