JACK Audio Connection Kit - Qt GUI Interface
JACK Audio Connection Kit - Qt GUI Interface[Intro] [Screenshots] [Requirements] [Downloads] [CVS] [Installation] [Configuration] [Bugs] [Support] [Acknowledgements]
QjackCtl is a simple Qt application to control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure.
Written in C++ around the Qt4 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.

The software requirements for build and runtime are listed as follows:
Mandatory:
Optional (opted-in at build time):
Latest release
2008-06-07 Patchbay JACK-MIDI, file logging and X11 uniqueness.
qjackctl-0.3.3.tar.gz
Previous and older releases, including the change log, are also available here. You may also check out from the latest bleeding edge development source tree, using CVS.
The installation procedure follows the standard for source distributions. In the extracted source directory, just do:
./configure[--prefix=prefix]
make
and optionally as root:
make install
This procedure will end installing the following couple of files:
/bin/qjackctl/share/pixmaps/qjackctl.png/share/applications/qjackctl.desktopJust launch prefix/bin/qjackctl and you're off (hopefully).
Note that the default installation path prefix is /usr/local .
Qjackctl holds its settings and configuration state per user, in a file
located as $HOME/.config/rncbc.org/QjackCtl.conf. Normally,
there's no need to edit this file, as it is recreated and rewritten everytime
qjackctl is run.
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.
Qjackctl is open source free software. For bug reports, feature requests, discussion forums, mailling lists, or any other matter related to the development of this piece of software, please use the Sourceforge project page.
You can also find timely and closer contact information on my personal web site.
Qjackctl's user interface primordial layout (and the whole idea for that matter) was partially borrowed from Lawrie Abbott's jacko project, which was just taken from wxWindow/Python into the Qt/C++ arena.
Since 2003-08-06, qjackctl has been included in the awesome Planet CCRMA software collection. Thanks a lot Fernando!
This project has also a freshmeat.net entry.
Dated from 2004-06-08, an online article written by no one else but Dave Phillips, has been published on Linux Journal, introducing you to Qjackctl and also QSynth. Please have a read:
At the Sounding Edge: Using QSynth and QJackCtl.
It's not on every regular day that you get to see one piece of the trade pointing two of your creations right in the title, is it?
Thanks Dave! You rule!
