QjackCtl is a simple Qt application to control the JACK sound server (http://jackaudio.org), for the Linux Audio infrastructure.
Written in C++ around the Qt4 toolkit for X11, most exclusively using Qt Designer.
Provides a simple GUI dialog for setting several JACK server parameters, which are properly saved between sessions, and a way control of the status of the audio server. With time, this primordial interface has become richer by including a enhanced patchbay and connection control
