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.
