NAME

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
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
