NAME
oggdec - simple decoder, Ogg Vorbis file to PCM audio file (Wave or
RAW).
SYNOPSIS
oggdec [ -QhV ] [ -b bitspersample ] [ -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. 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, endianness=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
