[linux-audio-dev] [ANN] Linux Audio Conference (LAC2006) dates

by Frank Neumann

Hi all, this is a pre-announcement to inform you that the 4th International Linux Audio Conference (or LAC2006 for short) will take place on Thursday, April 27th - Sunday, April 30th, 2006 at the ZKM in Karlsruhe, Germany It will again be supported by the Institute for Music and Acoustics of the ZKM, and will be (most probably) organized by Goetz Dipper of said institute and myself. We are only starting up the organizational work right now, so this is not the formal Call for Papers/Music/Workshops yet - that will follow in early October (and will look similar to that of last year). This mail is only to allow you to plan for this conference early and think about possible topics that you might want to present. Oh, and we will also need helping hands for all kinds of work - any offers to work with us on planning and running the conference are most welcome. Questions about the conference can already be sent to our "OrgaTeam" list address at lac2006 at zkm dot de. The web page for the conference is again at http://lac.zkm.de - though there is no new content yet. More details, as mentioned, in October. Greetings, Frank and Goetz

[linux-audio-dev] JackMix 0.1.0 released

by Arnold Krille

Yes, after more than a year there is another JackMix release! If you just want to download it: http://dillenburg.dyndns.org/~arnold/node/267 (also has some comments and install-instructions) You don't know what JackMix is? - It aims to be a mixing-console for your computer. It uses Jack, the professional sound server and does pure mixing, no effects or routing (there are other good apps for that). For more info read http://dillenburg.dyndns.org/~arnold/wiki/goto/JackMix:intro This new release includes a dir where I did some first tests with OSC, which I plan to use for communication between the mixer-server and the gui(s). Until now its just a lib and two test-apps in that dir. If you want, you can take a look at it... Some other concepts[*] are about to find their way into JackMix real soon, which implies another phase of heavy rewriting (and not so many releases). Have a nice day, Arnold [*] Reading "Design Patterns" is truly inspiring... -- visit http://dillenburg.dyndns.org/~arnold/ --- Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich verhindern könnte, würde ich mir noch heute einen Stapel Brenner und einen Sack Rohlinge kaufen.

[linux-audio-dev] Behringer firmware update

by Jens M Andreasen

Hi! So I counted the pennies, scratched my head more than twice, investigated alternatives, slept unruly and finally decided that a BCR2000 is the way to go. phew ... :) I have a firmware update here, looks like a sysex block (F0 ... ... F7) and with the filename extender 'syx' I am pretty sure it is so. In order to improve Behringers support for Linux, I should give some feedback, right? They have a failproof update.exe solution for Windows (but none for Mac nor Linux.) As far as I can see, this is the kind of job 'amidi' was designed to do. Now, what would an amidi command look like that guarantees to update each and every midi-device found with said sysex file? mvh // Jens M andreasen

[linux-audio-dev] Simultaneous Output Audio Engine?

by Thomas Vecchione

Evening- I was looking at starting a coding project for my work(Theaterical Sound Designer) and one of the things I was looking at doing is adding a playback engine to be used in a live situation. For this end I would need an audio engine capable of simultaneous file playback across the same or multiple audio interfaces, preferably using Jack. I was wondering if there was a good engine out there that already existed to accomplish this? Would Like: Just the engine, ability to program UI seperately. Ability to control basic concepts like Volume and Pan Possible Surround Output(5.1) and appropriate Pan implementation. Ability to play multiple files simultaneously, outputting either to the same interface or seperate interfaces Jack Compatibility Eventually I would love to be able to add things like LADSPA support and such to this program. My goal is a program that I can use to program in automation(Basic) in terms of Volume and Pan, and hopefully eventually Automation in terms of the Plugins used. The Main Goal of the program is to be used for playing Music and Sound Effects in Live Theater, however it will also be used to organize paperwork and such so that anything related to a production can be pulled up on the computer at any given time. I would also like to look into a good Midi Library, specificly for sending Midi Control Messages out over an interface to control external equipment. And since i am pretty new to audio programming, and pretty much can be considered a newcomer to programming in general I would love any suggestions on reading material for programming for audio, as I would imagine there are a few accepted and unaccepted tricks to keep a low latency system up, but also for minimizing HD load times and prebuffering clips in memory to allow for faster access etc. I doubt I will be using this right off hand, I am sticking to programming easier things for a reason for right now;) Seablade

[linux-audio-dev] [ANN] Snd-ls V0.9.5.3 and Mammut V0.21

by Kjetil Svalastog Matheussen

http://www.notam02.no/arkiv/src/ http://www.notam02.no/arkiv/src/snd/ Snd-ls ****** Snd-ls is a distribution of the sound editor Snd. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. 0.9.5.1 -> 0.9.5.3 ------------------ -Reduced the startup-time radically. -Reduced memory usage. -Realtime priority when playing when using jack. -Fixed window auto-sizing. -Turned off off-turning of mlockall(MCL_FUTURE) to avoid being zombified from jack. -Fixed some things in rt-compiler.scm and snd_conffile.scm Mammut ****** Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. 0.20 -> 0.21 ------------ -Set realtime priority for the player thread to ensure clickless playing. -Fixed some trouble when exiting. --

[linux-audio-dev] sWONDER update and news

by Marije Baalman

Hi all, after quite some time, I now released a new version of WONDER, version 2.0.8. This version features the GUI updates that were announced at the LAD this year, as well as a lot of restructuring in the code behind, making the framework more robust (less crashes!), and more easily extendible. For example, it should be much easier now to create a text based interface to WONDER. However, one little bug, which I still have to work on in the score creation of the composition tool, kind of renders that part of the program not very useful right now, but I didn't want to wait for another month with this release (I'll be away for the next couple of weeks)... Grid definition and playing should work fine. Details in the NEWS and KNOWNBUGS files in the tarball. I made a separate package for the manual/help files, as these update less often, and are quite big. Furthermore, there is now a CVS version at sourceforge as well, and I created a mailinglist there for those who wish to get updates on WONDER, and as a forum for questions about using WONDER in general, and bug-reporting. As this list gets archived, this might save me from answering some questions more than once :) Subscription at: http://lists.sourceforge.net/lists/listinfo/swonder-list More information: http://gigant.kgw.tu-berlin.de/~baalman/ Download from: https://sourceforge.net/projects/swonder/ Yours sincerely, Marije Baalman

[linux-audio-dev] [OT] sourceforge cvs non-interactively?

by Juhana Sadeharju

Hello. Could anyone figure out how to get sourceforge cvs non-interactively? I could not figure out how I could give the empty password to the script. The cvs login always seem to ask the password interactively. The cvs co does not work without cvs login. cvs manual says how to do it, but it does not work for some reason. My mistage? I just want archive a plenty of projects automatically. The cvsroot files are rarely updated at sourceforge, and the cvsroot file downloading is too often interrupted by their server.

[linux-audio-dev] Marian soundcards

by Marije Baalman

Hi all, could anyone have a look whether the documents listed here: http://developers.marian.de/ are indeed sufficient information to write an ALSA driver for one of these cards? There are quite a few people interested in getting such a card working on Linux, and the last message from Marian is that they supply this information to write drivers. My question though, whether this is enough, or not. Unfortunately, the most interesting card they have (the UCON CX) is not amongst those for which they supply info... sincerely, and thanks, Marije

[linux-audio-dev] WONDER Status, Mac Port

by Stephen Travis Pope

Hello all, I'm looking into porting SWONDER 2.0.5 to Mac OSX 10.4. I noticed that it requires Qt 3.X installed the old way (libs rather than Mac frameworks). Has anyone updated it to Qt 4.0? Is there already a Mac port (and xcode project) available? ...any reply appreciated... mit freundlichen Grüssen, stp -- Stephen Travis Pope -- http://create.ucsb.edu/~stp Center for Research in Electronic Art Technology, University of California, Santa Barbara Really—I don't know what the meaning or purpose of life is. But it looks exactly as if something were meant by it. — C. G. Jung
