METAFLAC(1)METAFLAC(1)NAMEmetaflac - program to list, add, remove, or edit metadata
in one or more FLAC files.
SYNOPSISmetaflac [ 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 speci-
fied).
--no-filename
Do not prefix each output line with the FLAC file
name (the default if only one FLAC file is speci-
fied).
--dont-use-padding
By default metaflac tries to use padding where pos-
sible 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_COM-
MENT 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 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
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 vor-
bisgain. 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, 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. Exam-
ple: --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 included or ignored with this
option. Use only one of --block-type or
--except-block-type. The valid block types
are: STREAMINFO, PADDING, APPLICATION, SEEK-
TABLE, VORBIS_COMMENT. 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" APPLICA-
TION:0xXXXXXXXX The APPLICATION block(s)
whose hexadecimal big- endian representation
of the 4-byte ID is "0xXXXXXXXX". For the
example "abcd" above the hexadecimal equiv-
alalent 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-for-
mat=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 meta-
data. 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.
