jack_mixer is a GTK JACK audio mixer app with a look similar to its hardware counterpart. It has lot of useful features, apart from being able to mix multiple JACK audio streams. It is licensed under GPL version 2 (or later). https://rdio.space/jackmixer/ https://rdio.space/jackmixer/tarballs/jack_mixer-12.tar.gz Changes in version 12? ---------------------- * Added reporting of the current volume through SIGUSR1 signal to jack_mix_box. * Reset color of over 0db/NaN peak on click. * Fixed memory leaks. * Fixed some Python 3 compatibility leftovers. And there is now a GitHub project for your features, or feature requests, bugs, etc. -> https://github.com/jack-mixer/jack_mixer With contributions from Daniel Sheeler and Athanasios Silis, thanks!
