oggdec (1) Linux Manual Page
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, –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- 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
