JACK-STDOUT(1) General Commands Manual JACK-STDOUT(1) NAME 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) -n, --name CLIENTNAME Set JACK client name (default: jstdout) -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.
