jack-stdout - write JACK audio data to stdout SYNOPSIS
jack-stdout [OPTIONS] port1 [ port2 ...] DESCRIPTION
jack-stdout captures audio from JACK and writes raw data to standard-output. The number of given ports detemine the number of audio channels that are used. If more than one channel is given, the audio-sample data will be interleaved. OPTIONS
-b, --bitdepth BITS Specify the bit-depth of each sample. For integer-encoding this can be 16 or 24. The default is 16. This setting is only used for integer encoding: Floating-point samples will always be 32 bit wide. -d, --duration SEC Specify the time for which jack-stdout should run in seconds. A value less than 1 means to run indefinitely. The default is 0. -e, --encoding FORMAT Set the output format of the data: signed-integer, unsigned-integer, floating-point (default: signed) -h, --help Print a brief usage information -L, --little-endian Write little-endian data or native-byte-order float (this is the default) -B, --big-endian Output big-endian data or swap the byte-order of floating-point -q, --quiet Inhibit usual output. This affects information and buffer-overflow warnings but not setup-errors. -S, --bufsize SAMPLES Choose the internal buffer-size in samples. The default size is 65536. The given value will be multiplied by the number of channels and bit-depth to get the size of the ring-buffer. EXAMPLES

oggdec(1) Vorbis Tools oggdec(1) 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 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. Like- wise, 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 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 AUTHORS
