[linux-audio-announce] ANN: k_jack v0.0.0.5 and Mammut v0.15

k_jack is a jack reimplementation, and mammut is a very special sound transformating sound editor. Download from http://www.notam02.no/arkiv/src/ New in mammut v0.14->v0.15: --------------------------- -Removed the synth transform. It was not supposed to be there and had no function. -Fixed the wobble transform. Segfaulted with mono-files. (Bug found by Dave Phillips) k_jack V0.0.0.5 ALPHA - EXPERIMENTAL ------------------------------------- ABOUT k_jack currently consists of k_jackd~, libk_jack and libaipc. k_jackd~ is a jack server external for pure-data. libk_jack is (supposed to be) a (somewhat) libjack compatible library. Jack applications that want to contact k_jackd~ instead of jackd must (somehow) be linked with libk_jack and libaipc instead of libjack. k_jackd~ does not speak with libjack, and jackd does not speak with libk_jack. libaipc is a library for audio interprocess communication, based on code from the vstserver. A preview version is included with this version of k_jack. (API is not settled.) By using libaipc for interprocess communication, and letting PD take care of various low/mid/high-level audio-stuff, only a few hundred lines of code is currently used for this implementation of a simple jack system. k_jackd~ and libk_jack are not based on the jack sourcecode found at jackit.sf.net, except for protos in the header files. COMPILE 1. Go into the aipc/src folder and write make to compile up libaipc.a 2. Go into the library folder and write make to compile up libk_jack.a 3. Write make to compile up k_jack~.pd_linux. 4. Relink you jack application(s) somehow. USAGE 1. Start pd with the "-lib k_jackd~" option. 2. Start a jack application linked with libk_jack. 3. Make an object in pd called "k_jackd~ <clientname>". Correct number of inlets and outlets will be made automaticly. That should be it. Later, when things get more stable, point 3 can do point 2 automaticly. WHY use k_jackd~ ? 1. Simple. Only the clientname is used, not the portnames. 2. Easy and powerful interface to control the audioflow. 3. Good performance. Shouldn't be necessary to run as root. TESTED CLIENTS simple_client, freqtweak, ceres. BUGS Crashes pretty often. Does not clean up. Huge risk of not freeing shared memory in the current implementation: Client must exit before server, and client must not crash. And server must not crash.
