NAME

       metaflac —       program to list, add, remove, or edit metadata in one or more FLAC files.

SYNOPSIS

       metaflac [options ]  [operations ]  FLACfile

DESCRIPTION

       Use  metaflac  to  list, add, remove, or edit metadata in one or more FLAC files.  You may
       perform one major operation, or many shorthand operations at a time.

OPTIONS

       --preserve-modtime
                 Preserve the original modification time in spite of edits.

       --with-filename
                 Prefix each output line with the FLAC file name (the default if  more  than  one
                 FLAC file is specified).

       --no-filename
                 Do  not prefix each output line with the FLAC file name (the default if only one
                 FLAC file is specified).

       --no-utf8-convert
                 Do not convert tags from UTF-8 to local charset, or vice versa. This  is  useful
                 for scripts, and setting tags in situations where the locale is wrong.

       --dont-use-padding
                 By  default  metaflac tries to use padding where possible to avoid rewriting the
                 entire file if the metadata size changes.  Use this option to tell  metaflac  to
                 not take advantage of padding this way.

SHORTHAND OPERATIONS

       --show-md5sum
                 Show the MD5 signature from the STREAMINFO block.

       --show-min-blocksize
                 Show the minimum block size from the STREAMINFO block.

       --show-max-blocksize
                 Show the maximum block size from the STREAMINFO block.

       --show-min-framesize
                 Show the minimum frame size from the STREAMINFO block.

       --show-max-framesize
                 Show the maximum frame size from the STREAMINFO block.

       --show-sample-rate
                 Show the sample rate from the STREAMINFO block.

       --show-channels
                 Show the number of channels from the STREAMINFO block.

       --show-bps
                 Show the # of bits per sample from the STREAMINFO block.

       --show-total-samples
                 Show the total # of samples from the STREAMINFO block.

       --show-vendor-tag
                 Show the vendor string from the VORBIS_COMMENT block.

       --show-tag=name
                 Show all tags where the field name matches 'name'.

       --remove-tag=name
                 Remove all tags whose field name is 'name'.

       --remove-first-tag=name
                 Remove first tag whose field name is 'name'.

       --remove-all-tags
                 Remove all tags, leaving only the vendor string.

       --set-tag=field
                 Add  a  tag.   The  field  must comply with the Vorbis comment spec, of the form
                 "NAME=VALUE".  If there is currently no tag block, one will be created.

       --set-tag-from-file=field
                 Like --set-tag, except the VALUE is a  filename  whose  contents  will  be  read
                 verbatim  to  set  the  tag  value.   Unless --no-utf8-convert is specified, the
                 contents will be converted to UTF-8 from the local charset.  This can be used to
                 store  a cuesheet in a tag (e.g.  --set-tag-from-file="CUESHEET=image.cue").  Do
                 not try to store binary data in tag fields!  Use APPLICATION blocks for that.

       --import-tags-from=file
                 Import tags from a file.  Use '-' for stdin.  Each line should be  of  the  form
                 NAME=VALUE.  Multi-line comments are currently not supported.  Specify --remove-
                 all-tags and/or --no-utf8-convert before --import-tags-from  if  necessary.   If
                 FILE is '-' (stdin), only one FLAC file may be specified.

       --export-tags-to=file
                 Export  tags  to  a  file.   Use  '-' for stdout.  Each line will be of the form
                 NAME=VALUE.  Specify --no-utf8-convert if necessary.

       --import-cuesheet-from=file
                 Import a cuesheet from a file.  Use '-' for stdin.  Only one FLAC  file  may  be
                 specified.   A  seekpoint  will be added for each index point in the cuesheet to
                 the SEEKTABLE unless --no-cued-seekpoints is specified.

       --export-cuesheet-to=file
                 Export CUESHEET block to a cuesheet file,  suitable  for  use  by  CD  authoring
                 software.   Use  '-'  for  stdout.   Only  one FLAC file may be specified on the
                 command line.

       --import-picture-from={FILENAME|SPECIFICATION}
                 Import a picture and store it in  a  PICTURE  metadata  block.   More  than  one
                 --import-picture-from  command  can  be  specified.   Either  a filename for the
                 picture  file  or  a  more  complete  specification  form  can  be  used.    The
                 SPECIFICATION  is  a  string  whose  parts are separated by | (pipe) characters.
                 Some parts may be left  empty  to  invoke  default  values.   FILENAME  is  just
                 shorthand for "||||FILENAME".  The format of SPECIFICATION is

                 [TYPE]|[MIME-TYPE]|[DESCRIPTION]|[WIDTHxHEIGHTxDEPTH[/COLORS]]|FILE

                 TYPE is optional; it is a number from one of:

                 0: Other

                 1: 32x32 pixels 'file icon' (PNG only)

                 2: Other file icon

                 3: Cover (front)

                 4: Cover (back)

                 5: Leaflet page

                 6: Media (e.g. label side of CD)

                 7: Lead artist/lead performer/soloist

                 8: Artist/performer

                 9: Conductor

                 10: Band/Orchestra

                 11: Composer

                 12: Lyricist/text writer

                 13: Recording Location

                 14: During recording

                 15: During performance

                 16: Movie/video screen capture

                 17: A bright coloured fish

                 18: Illustration

                 19: Band/artist logotype

                 20: Publisher/Studio logotype

                 The  default  is  3 (front cover).  There may only be one picture each of type 1
                 and 2 in a file.

                 MIME-TYPE is optional; if left blank, it will be detected from  the  file.   For
                 best  compatibility  with  players,  use  pictures  with MIME type image/jpeg or
                 image/png.  The MIME type can also be --> to mean that FILE is actually a URL to
                 an image, though this use is discouraged.

                 DESCRIPTION is optional; the default is an empty string.

                 The  next part specifies the resolution and color information.  If the MIME-TYPE
                 is image/jpeg, image/png, or image/gif, you can usually  leave  this  empty  and
                 they  can  be  detected from the file.  Otherwise, you must specify the width in
                 pixels, height in pixels, and color depth in bits-per-pixel.  If the  image  has
                 indexed colors you should also specify the number of colors used.  When manually
                 specified, it is not checked against the file for accuracy.

                 FILE is the path to the picture file to be imported, or the URL if MIME type  is
                 -->

                 For   example,   "|image/jpeg|||../cover.jpg"   will  embed  the  JPEG  file  at
                 ../cover.jpg, defaulting to type 3 (front cover) and an empty description.   The
                 resolution and color info will be retrieved from the file itself.

                 The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will
                 embed the given URL, with type 4 (back cover), description "CD", and a  manually
                 specified resolution of 320x300, 24 bits-per-pixel, and 173 colors.  The file at
                 the URL will not be fetched; the URL itself is stored in  the  PICTURE  metadata
                 block.

       --export-picture-to=file
                 Export  PICTURE block to a file.  Use '-' for stdout.  Only one FLAC file may be
                 specified on the command line.  The first PICTURE block will be exported  unless
                 --export-picture-to  is  preceded  by  a  --block-number=# option to specify the
                 exact metadata block to extract.  Note that the block number is the one shown by
                 --list.

       --add-replay-gain
                 Calculates the title and album gains/peaks of the given FLAC files as if all the
                 files were part of one album, then stores them as FLAC tags.  The tags  are  the
                 same  as  those  used by vorbisgain.  Existing ReplayGain tags will be replaced.
                 If only one FLAC file is given, the album and title  gains  will  be  the  same.
                 Since  this operation requires two passes, it is always executed last, after all
                 other operations have been completed  and  written  to  disk.   All  FLAC  files
                 specified  must  have  the same resolution, sample rate, and number of channels.
                 The sample rate must be one of 8, 11.025, 12, 16, 18.9, 22.05, 24, 28, 32, 37.8,
                 44.1, 48, 56, 64, 88.2, 96, 112, 128, 144, 176.4, or 192kHz.

       --scan-replay-gain

                 Like  --add-replay-gain, but only analyzes the files rather than writing them to
                 the tags.

       --remove-replay-gain
                 Removes the ReplayGain tags.

       --add-seekpoint={#|X|#x|#s}
                 Add seek points to a SEEKTABLE block.  Using #, a  seek  point  at  that  sample
                 number  is  added.   Using  X,  a placeholder point is added at the end of a the
                 table.  Using #x, # evenly spaced seek points will be added, the first being  at
                 sample  0.  Using #s, a seekpoint will be added every # seconds (# does not have
                 to be a whole number; it can be, for example, 9.5, meaning a seekpoint every 9.5
                 seconds).   If  no  SEEKTABLE block exists, one will be created.  If one already
                 exists, points will be added to the existing table, and any duplicates  will  be
                 turned  into  placeholder points.  You may use many --add-seekpoint options; the
                 resulting SEEKTABLE will be the unique-ified union of all such values.  Example:
                 --add-seekpoint=100x  --add-seekpoint=3.5s will add 100 evenly spaced seekpoints
                 and a seekpoint every 3.5 seconds.

       --add-padding=length
                 Add a padding block of the given length (in bytes).  The overall length  of  the
                 new  block  will  be  4  +  length;  the extra 4 bytes is for the metadata block
                 header.

MAJOR OPERATIONS

       --list    List the contents of one or more metadata blocks to  stdout.   By  default,  all
                 metadata  blocks are listed in text format.  Use the following options to change
                 this behavior:

                 --block-number=#[,#[...]]
                           An optional comma-separated list of block  numbers  to  display.   The
                           first block, the STREAMINFO block, is block 0.

                 --block-type=type[,type[...]]

                 --except-block-type=type[,type[...]]
                           An  optional  comma-separated  list  of  block types to be included or
                           ignored with this option.  Use only one of --block-type  or  --except-
                           block-type.    The   valid   block  types  are:  STREAMINFO,  PADDING,
                           APPLICATION, SEEKTABLE, VORBIS_COMMENT, PICTURE.  You may narrow  down
                           the types of APPLICATION blocks displayed as follows:

                           APPLICATION:abcd         The APPLICATION block(s) whose textual repre-
                           sentation of the  4-byte  ID  is  "abcd"  APPLICATION:0xXXXXXXXX   The
                           APPLICATION  block(s)  whose hexadecimal big- endian representation of
                           the 4-byte ID is "0xXXXXXXXX".   For  the  example  "abcd"  above  the
                           hexadecimal equivalalent is 0x61626364

                        Note:

                                  if both --block-number and --[except-]block-type are specified,
                                  the result is the logical AND of both arguments.

                 --application-data-format=hexdump|text
                           If the application block you are displaying contains binary  data  but
                           your --data-format=text, you can display a hex dump of the application
                           data contents instead using --application-data-format=hexdump.

       --remove  Remove one or more metadata blocks from the metadata.  Unless --dont-use-padding
                 is  specified, the blocks will be replaced with padding.  You may not remove the
                 STREAMINFO block.

                 --block-number=#[,#[...]]

                 --block-type=type[,type[...]]

                 --except-block-type=type[,type[...]]
                           See --list above for usage.

                        Note:

                                  if both --block-number and --[except-]block-type are specified,
                                  the result is the logical AND of both arguments.

       --remove-all
                 Remove  all  metadata  blocks  (except  the STREAMINFO block) from the metadata.
                 Unless --dont-use-padding  is  specified,  the  blocks  will  be  replaced  with
                 padding.

       --merge-padding
                 Merge adjacent PADDING blocks into single blocks.

       --sort-padding
                 Move  all PADDING blocks to the end of the metadata and merge them into a single
                 block.
