QjackCtl - JACK Audio Connection Kit Qt GUI Interface ----------------------------------------------------- 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 Qt framework 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 features. Homepage: https://qjackctl.sourceforge.io http://qjackctl.sourceforge.net License: GNU General Public License (GPL) Requirements ------------ The software requirements for build and runtime are listed as follows: Mandatory: - Qt framework, C++ class library and tools for cross-platform application and UI development https://qt.io/ - JACK Audio Connection Kit https://jackaudio.org/ Optional (opted-in at build time): - ALSA, Advanced Linux Sound Architecture https://www.alsa-project.org/ Installation ------------ Unpack the tarball and in the extracted source directory: cmake [-DCMAKE_INSTALL_PREFIX=/usr/local] -B build cmake --build build [--parallel <Njobs>] and optionally, as root: sudo cmake --install build See also the README.cmake file in the source distribution. Configuration ------------- 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. Bugs ---- Probably plenty still, QjackCtl maybe considered on beta stage already. It has been locally tested since JACK release 0.98.0, with custom 2.4 kernels with low-latency, preemptible and capabilities enabling patches. As for 2.6 kernels, the emergence of 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. Support ------- 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 (https://sourceforge.net/projects/qjackctl). You can also find timely and closer contact information on my personal web site (https://www.rncbc.org). Acknowledgments --------------- QjackCtl's user interface layout (and the whole idea for that matter) was partially borrowed from origoinal Lawrie Abbott's jacko project, which was taken from wxWindow/Python into the Qt/C++ arena. Since 2003-08-06, qjackctl has been included in the awesome Planet CCRMA (http://ccrma-www.stanford.edu/planetccrma/software/) software collection. Thanks a lot Fernando!
