06/02/14 JackLab YAST repository available. See Additional_YaST_Package_Repositories#JackLab

06/01/08 JAD kernel released, see: http://jacklab.net/phpBB2/viewtopic.php?t=29

05/12/16 Added a team list, some small corrections about the kernel

05/10/18 Added new documentation: "A little guide how to switch SL 10.0 to an audio workstation." RT Kernel Instructions

Project Description

JackLab supports openSUSE to have an extension (distribution) for audio/media and become a fast digital audio workstation with an audio-realtime-kernel and professional tools for music production up to VST instruments, similar to Planet CCRMA for Fedora Core, and aGNUla for Debian.

JackLab supports musicians/media artists by trying to find out the most user-friendly way - 1-click setups working for non-technical users, simple administration by YaST and optionally APT. Furthermore the optimization of the kernel, the audio drivers and the setting of proper rights is explored, which is not trivial concerning real-time audio processes controlled by Jack.

JackLab's principal aim is to watch current software, make recommendations to software packagers, test it, talk about it, offer tutorials and user4user support. Negotiations about a distribution of these upgrades e.g. with cd-roms as an downloadable image or in magazines have started.

OpenSUSE CD JAD image in detail: (in preparation)

  • YaST controlled installation

An entire YaST enviroment including all graphic front-ends In addition, APT4RPM and the GUI Synaptic

  • Ext3 as the default file system

Reiser journaling file systems can extremely negatively affect the cache behavior from jackd and can degrade system performance.

  • Graphic basic system with e17 and some KDE apps

For maximal performance, audio systems need a minimal window manager. KDE consumes too much resources that are needed by the realtime audio processes. The WM should be preconfigured in such a way that all audio programs are arranged together clearly in the menu. Nevertheless, a file manager like Konqueror is essential for the GUI oriented user. (kde-base)

  • RT audio kernel with PAM for SCHED_FIFO priorities

We're using a kernel according to the SUSE standard kernel with all patches. We're using realtime - preemt patches from Ingo Molnar. The patch broke, depends on the kernel version, some drivers. For SUSE 10.0 we have an fixed PAM 0.80 available, because for unknown reasons the orginal SUSE PAM didn't work with rt-prios for audio. 10.1 seemed to be right.

  • Selected Pro Audio Media Software

JACK, qjackctl, Ardour, Hydrogen, MusE, rosegarden, seq24, sooperlooper, Alsamodular, ZynAddSubFX, Rezound, LADSPA, Alsatools-GUI, Linuxsampler/Qsampler, Qsynth, Freewheeling, speciman, mplayer (jack enabled), cinelerra... (and more)

  • Internet basic system

Firefox, Thunderbird, Xchat

  • Selected multimedia applications

XMMS, Gimp, k3b ... (and more).

This entrance system can be of course be easily extended to full openSUSE - either with YaST or APT. In addition, non-free extensions are offered in the APT repositories, like mp3 support, w32codecs and VST support.
