oggdec(c)                  Vorbis Tools                 oggdec(c)



NAME
       oggdec - simple decoder, Ogg Vorbis file to PCM audio file
       (WAV or RAW).


SYNOPSIS
       oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [
       -R  rawness ] [ -s signedness ] [ -o outputfile ] file ...


DESCRIPTION
       oggdec decodes Ogg Vorbis files into PCM-encoded  ("uncom-
       pressed") 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 n, --raw=n
              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.


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 1 -e 1 -b 16 enabler.ogg
              oggdec  -R  1  -e  1  -b  16  -o  enabler.raw  -  <
              enabler.ogg
              oggdec  -R  1  -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
