       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.
