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 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 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.



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
