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.
