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 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
features.

Requirements
------------

The software requirements for build and runtime are listed as follows:

  Mandatory:

  - Qt4 (core, gui, xml), C++ class library and tools for
        crossplatform development and internationalization
        http://www.trolltech.org/products/qt/

  - JACK Audio Connection Kit
        http://jackaudio.org/

  Optional (opted-in at build time):

  - ALSA, Advanced Linux Sound Architecture
        http://www.alsa-project.org/


Installation
------------

The installation procedure follows the standard for source distributions:

    ./configure [--prefix=/usr/local]
    make

and optionally as root:

    make install

This procedure will end installing the following couple of files:

    ${prefix}/bin/qjackctl
    ${prefix}/share/pixmaps/qjackctl.png
    ${prefix}/share/applications/qjackctl.desktop

Just launch ${prefix}/bin/qjackctl and you're off (hopefully).

If you're checking out from CVS, you'll have to prepare the configure
script just before you proceed with the above instructions:

   make -f Makefile.cvs


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, 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.


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 (http://sourceforge.net/projects/qjackctl).

You can also find timely and closer contact information on my personal
web site (http://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.
