oggdec - Man Page

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 appropriate.

If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is specified. Likewise, 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 signed 16-bit (default options):

oggdec enabler.ogg

Decode a file enabler.ogg to enabler.raw as headerless little-endian signed 16-bit:

oggdec --raw 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
