Qjackctl software is a simple Qt application that can control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure.

Written in C++ around the Qt3 toolkit for X11, most exclusively using Qt Designer.

Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features.

Bugs:

Probably plenty still, but qjackctl it's now considered on beta stage already. It has been locally tested since JACK release 0.98.0, on SuSE 9.1, Mandrake 10.0 and Fedora Core 1, with custom 2.4 kernels with low-latency, preemptible and capabilities enabling patches. As for 2.6 kernels, the capabilities patch may also apply but the emergence of the Realtime Linux Security Module (LSM) and Ingo Molnar's Realtime Preemption kernel patch it's being now recommended for your taking benefit of the realtime and low-latency audio pleasure JACK can give.

What's New in This Release:
GPL address update.
All window captions can now be set smaller as tool-widgets. This option takes effect when child windows are kept always on top.
For the brave of heart, specially the ones brave enough to try with Stephane Letz's jackdmp, a win32 build should be now possible.
The main window button text labels are now optional (after a kind suggestion by Geoff Beasley, thanks).
Increse default maximum number of ports setting from 128 to 256.
Initial freebob backend driver support. Also changed the coreaudio backend driver command line device name/id parameter (EXPERIMENTAL).
Closing the main window while not as an active JACK client, nor under a server running state, will just quit the whole application, even though the system-tray icon option is in effect.
The most relevant transport commands (Rewind, Play and Pause) are now made available on the main window context popup menu.
The post-shutdown script is now also being called when using the Stop button, whether the jackd server has been started internally or not. The initial hard-coded default is now on and set to `killall jackd` (as a workaround to an old request from Stephane Letz).
The main window buttons display are now optional. One can choose whether the left, right and/or transport buttons are hidden, making it for a total of six different modes for the main window presentation (after a much simpler suggestion from Paul Davis and Stephane Letz).
Added configure support for x86_64 libraries (UNTESTED).
