JACK audio-port for the unix commandline.
jack-stdout is a small tool that writes JACK audio-sample data to buffered standard output. jack-stdin reads raw audio data from standard-input and writes it to a JACK audio port.
jack-stdout works OOTB with JustEport as stdin to airtunes™ tool, and can be used with any command-line utilities like oggenc, sox, aacplusenc, lame, ffmpeg,..
By default jack-stdout writes 16 bit signed integer raw audio data (much like mpg123 -s) at JACK's samplerate, but it can output signed/unsigned 8/16/24/32 bit integer and 32bit floating-point data, both big/little endian.
See the included man-pages or run jack-stdout –help, jack-stdin –help for usage information.
