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.

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.
