NAME

oggdec - simple decoder, Ogg Vorbis file to PCM audio file (WAV 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 WAV 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 WAV format to stdout is a bad idea. WAV 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 WAV 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
