by Ivica Bukvic

Hi all, Just to share the good news that Linux got some exposure in the latest edition of the Organised Sound journal (pub. by UK's Cambridge Journals). Stuff covered is RTMix, as well as JACK/Linux audio. Big thanks go to Paul Davis for the help with the benchmark info, as well as everyone else in the Linux community who have made Linux a formidable multimedia platform. For more info on the journal see (it's just an abstract page about the actual journal -- I am still trying to find out how to locate the darn article online :-) http://titles.cambridge.org/journals/journal_catalogue.asp?mnemonic=oso Cheers!

[linux-audio-announce] ecamegapedal 0.4.0 released

by Kai Vehmanen

1. A short summary of changes Sliders for parameter control and text inputs for lower and upper bounds have been added as well as support for LADSPA-1.1 and ecasound effect parameter hints. There has been some user interface improvements and a native JACK support has been added. Updated to use the new ecasound-2.2 libraries. --- 2. What is ecamegapedal? Ecamegapedal is a real-time effect processor software with a graphical user interface for controlling the effect parameters. It is meant to be used as a virtual guitar-fx or studio effect box. In addition to real-time operation, ecamegapedal also supports reading from and writing to audio files. All audio object and effect plugin types provided by the ecasound libraries are supported. This includes ALSA, JACK, OSS, aRts, over 20 file formats, over 30 effect types, LADSPA plugins and multi-operator effect presets. Ecamegapedal's implementation is based on ecasound and Qt libraries. Ecamegapedal is licensed under the GPL. --- 3. Changes since the last stable release * Added native JACK support. If compiled with JACK support enabled, ecamegapedal will upon startup fetch the current engine parameters from the JACK server, and initialize the ecamegapedal configuration to work with JACK. In practice this means that you don't have to manually set the buffersize and sample rate parameters to use ecamegapedal with JACK. * Support for LADSPA-1.1 and ecasound effect parameter hints. * Text inputs for overriding default upper and lower bounds for parameter values. * Sliders for controlling parameter values. * Pixmaps for transport control buttons. * Takes advantage of the newly released ecasound 2.2.0 libraries (does not work with older ecasound releases). * Should work with all released Qt2 and Qt3 versions. Tested with qt-2.3.2, qt-3.0.5 and qt-3.1.1. --- 4. Contributors Patches Kai Vehmanen Arto Hamara Bug Hunting Jaakko Prattala Justin Rosander Junichi Uekawa Feature proposals Dan Lyons --- 5.

[linux-audio-announce] [ANN] JACK TimeMachine 0.0.2

by Steve Harris

I've fixed some build issues and theoretically made it slightly more efficient. If you managed to build 0.0.1 theres no real point in you upgrading. Theres also now a webpage of sorts, with a screenshot ;) http://plugin.org.uk/timemachine/ - Steve

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

by Kjetil S. Matheussen

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. CONTACT Send ideas (especially about the k_jackd~ object syntax), comments (especially about the libaipc API), questions, code, food, etc. to k.s.matheussen(a)notam02.no --

[linux-audio-announce] ecawave development stopped

by Kai Vehmanen

Ecawave will no longer be actively developed. The Linux audio application scene has changed drastically since January of 2000 when the first version of ecawave was released. Nowadays there are many FOSS (free and open source software) audio file editors available for you to choose from. As replacements to ecawave I recommend: - Audacity - GLAME - GNUsound - Sweep - ... check the list at: http://freshmeat.net/search/?q=audio%20file%20editor&section=projects My thanks to all who have participated in ecawave development! -- http://www.eca.cx Audio software for Linux!

[linux-audio-announce] [ANN] JACK TimeMachine

by Steve Harris

http://plugin.org.uk/timemachine/ tarball, 100k. Depends on SDL, SDL_image, jack and libsndfile. I used to always keep a minidisc recorder in my studio running in a mode where when you pressed record it wrote the last 10seconds of audio to the disk and then caught up to realtime and kept recroding. The recorder died and haven't been able to replace it, so this is a simple jack app to do the same job. It has the advantage that it never clips and can be wired to any part of the jack graph. I've been using it to record occasional bursts of interesting noise from jack apps feeding back into each other. Usage: ./configure, make, make install, run jack_timemachine. Connect it up with a patchbay app. To start recording click in the window. To stop recording, click in the window. It writes out 32bit float WAV files called tm-<time>.wav, where <time> is the time the recording starts from. The prebuffer time and number of channels are set in a macro, defaults are 10s and 2. It works on my machine, and I'l fix major bugs, but I don't really have time to support another piece of software, so good luck :) If anyone wants to maintain it, feel free. May it preserve many interesting sounds for you, Steve
