vorbiscomment - List or edit comments in Ogg Vorbis files SYNOPSIS
vorbiscomment [-l] [-R] [-e] file.ogg vorbiscomment -a [ -c commentfile | -t "name=value" ] [-q] [-R] [-e] in.ogg [out.ogg] vorbiscomment -w [ -c commentfile | -t "name=value" ] [-q] [-R] [-e] in.ogg [out.ogg] DESCRIPTION
vorbiscomment Reads, modifies, and appends Ogg Vorbis audio file metadata tags. OPTIONS
-a, --append Append comments. -c file, --commentfile file Take comments from a file. The file is the same format as is output by the the -l option or given to the -t option: one element per line in 'tag=value' format. If the file is /dev/null and -w was passed, the existing comments will be removed. -h, --help Show command help. -l, --list List the comments in the Ogg Vorbis file. -q, --quiet Quiet mode. No messages are displayed. -t 'name=value', --tag 'name=value' Specify a new tag on the command line. Each tag is given as a single string. The part before the '=' is treated as the tag name and the part after as the value. -w, --write Replace comments with the new set given either on the command line with -t or from a file with -c. If neither -c nor -t is given, the new set will be read from the standard input. -R, --raw Read and write comments in UTF-8, rather than converting to the user's character set. -e, --escapes Quote/unquote newlines and backslashes in the comments. This ensures every comment is exactly one line in the output (or input), allowing to filter and round-trip them. Without it, you can only write multi-line comments by using -t and you can't reliably dis- tinguish them from multiple one-line comments. Supported escapes are c-style " ", " ", "\" and "". A backslash followed by anything else is an error. Note: currently, anything after the first "" is thrown away while writing. This is a bug -- the Vorbis format can safely store null characters, but most other tools wouldn't handle them anyway. -V, --version Display the version of vorbiscomment. EXAMPLES
To just see what comment tags are in a file: vorbiscomment -l file.ogg To edit those comments: vorbiscomment -l file.ogg > file.txt [edit the comments in file.txt to your satisfaction] vorbiscomment -w -c file.txt file.ogg newfile.ogg To simply add a comment: vorbiscomment -a -t 'ARTIST=No One You Know' file.ogg newfile.ogg To add a set of comments from the standard input: vorbiscomment -a file.ogg ARTIST=No One You Know ALBUM=The Famous Album <ctrl-d> TAG FORMAT
See for documentation on the Ogg Vorbis tag format, including a suggested list of canonical tag names. AUTHORS

oggdec - simple decoder, Ogg Vorbis file to PCM audio file (Wave or RAW). SYNOPSIS
oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s signedness ] [ -o outputfile ] file ... DESCRIPTION
oggdec decodes Ogg Vorbis files into PCM-encoded ("uncompressed") audio files, either Wave or RAW format. For each input file, oggdec writes to a filename based on the input filename, but with the extension changed to ".wav" or ".raw" as appro- priate. If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is specified. Like- wise, an output filename of - will cause output to be to stdout. Writing Wave format to stdout is a bad idea. Wave requires a seekable medium for the header to be rewritten after all the data is written out; stdout is not seekable. OPTIONS
-Q, --quiet Suppresses program output. -h, --help Print help message. -V, --version Display version information. -b n, --bits=n Bits per sample. Valid values are 8 or 16. -e n, --endian=n Set endianness for 16-bit output. 0 (default) is little-endian (Intel byte order). 1 is big-endian (sane byte order). -R, --raw Output in raw format. If not specified, writes Wave file (RIFF headers). -s n, --sign=n Set signedness for output. 0 for unsigned, 1 (default) for signed. -o filename, --output=filename Write output to specified filename. This option is only valid if one input [file] is specified, or if raw mode is used. EXAMPLES
Decode a file enabler.ogg to enabler.wav as little-endian unsigned 16-bit (default options): oggdec enabler.ogg Decode a file enabler.ogg to enabler.raw as headerless little-endian unsigned 16-bit: oggdec --raw=1 enabler.ogg Decode enabler.ogg to enabler.crazymonkey as unsigned 8-bit: oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg Decode enabler.ogg to enabler.raw as big-endian signed 16-bit (any of the following): oggdec -R -e 1 -b 16 enabler.ogg oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw Mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg to quux.wav, etc.): oggdec *.ogg AUTHORS
