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).
--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-vc-vendor
Show the vendor string from the VORBIS_COMMENT block.
--show-vc-field=name
Show all Vorbis comment fields where the the field name matches
'name'.
--remove-vc-field=name
Remove all Vorbis comment fields whose field name is 'name'.
--remove-vc-firstfield=name
Remove first Vorbis comment field whose field name is 'name'.
--remove-vc-all
Remove all Vorbis comment fields, leaving only the vendor
string in the VORBIS_COMMENT block.
--set-vc-field=field
Add a Vorbis comment field. The field must comply with the
Vorbis comment spec, of the form "NAME=VALUE". If there is
currently no VORBIS_COMMENT block, one will be created.
--import-vc-from=file
Import Vorbis comments from a file. Use '-' for stdin. Each
line should be of the form NAME=VALUE. Multi-line comments are
currently not supported. Specify --remove-vc-all and/or --no-
utf8-convert before --import-vc-from if necessary.
--export-vc-to=file
Export Vorbis comments to a file. Use '-' for stdin. 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. Only one FLAC file may be spec-
ified. A seekpoint will be added for each index point in the
cuesheet to the SEEKTABLE unless --no-cued-seekpoints is speci-
fied.
--export-cuesheet-to=file
Export CUESHEET block to a cuesheet file, suitable for use by
CD authoring software. Use '-' for stdin. Only one FLAC file
may be specified on the command line.
--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 in the VORBIS_COMMENT block. 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 speci-
fied 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.
--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-seek-
point=3.5s will add 100 evenly spaced seekpoints and a seek-
point every 3.5 seconds.
--add-padding=length
Add a padding block of the given length (in bytes). The over-
all 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
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. You may narrow down the types of APPLI-
CATION 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 hex-
adecimal 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.
