====== Jack Std-I/O ======

[[http://jackaudio.org|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 [[http://www.google.com/search?q=justeport|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.
