METAFLAC(1)									      METAFLAC(1)

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 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 spec-
	      ified.  A seekpoint will be added for each index point in the cuesheet to the SEEK-
	      TABLE unless --no-cued-seekpoints is specified.

       --export-cuesheet-to=file
	      Export CUESHEET block to a cuesheet file, suitable for use by  CD  authoring  soft-
	      ware.   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 specfies 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 opera-
	      tions 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, 22.05, 24, 32, 44.1, or 48 kHz.

       --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 num-
	      ber; 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 sec-
	      onds.

       --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 meta-
	      data 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,  VOR-
		     BIS_COMMENT.   You may narrow down the types of APPLICATION blocks displayed
		     as follows:

		     APPLICATION:abcd	     The APPLICATION block(s) whose textual repre- senta-
		     tion  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  con-
		     tents 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.
