jack-stdout - write JACK audio data to stdout


jack-stdout [OPTIONS] port1 [ port2 ...]


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.


-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.
