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)

       -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.

EXAMPLES
	 jack-stdout xmms_0:out_1 xmms_0:out_2 
	 | mono  ~/Desktop/Downloads/JustePort.exe - 10.0.1.6 0

	 jack-stdout -b 24 -e unsigned -B system:capture_1 system:capture_2 
	 | sox -t raw -r 48k -e unsigned -b 24 -B -c 2 - /tmp/recording.wav

	 jack-stdout system:capture_1 system:capture_2 
	 | oggenc -r -R 48000 -B 16 -C 2 - 
	 > /tmp/recording.ogg

	 jack-stdout system:capture_1 
	 | oggenc -r -R 48000 -B 16 -C 1 - 
	 | oggfwd -p -n "my live stream" localhost 5900 hackme live.ogg
