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 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. 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. See the flac option --picture for an explanation of the SPECIFICATION syntax.
|
|
--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, 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:
-
# : a specific sample number for a seek point
-
X : a placeholder point (always goes at the end of the SEEKTABLE)
-
#x : # evenly spaced seekpoints, the first being at sample 0
-
#s : a seekpoint 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=#
|
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.
