[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

[linux-audio-dev] OT: Licensing conflict

by Christoph Eckert

Hi all, I just started to learn some C++. Currently I'm working on some Qt MIDI tools. I've found some code which makes life for me much easier. The code is licensed under a MIT license and can be found here: http://www.music.mcgill.ca/~gary/rtmidi/index.html#license The free Qt version I use is under GPL. I wonder if I'm allowed to distribute a Qt application as a GPL application even if I include the classes mentioned above, or if I need to implement my MIDI connectivity by myself. Any opinion is much appreciated. Thanks & best regards ce

[linux-audio-dev] [ANN] dssi_convolve

by Florian Schmidt

Hi, this is the first public tarball of dssi_convolve, a DSSI wrapper around libconvolve. grab here: http://affenbande.org/~tapas/jack_convolve/dssi_convolve-0.0.2.tgz you need libconvolve-0.0.5.tgz for this, too (fixed some minor bugs) http://affenbande.org/~tapas/jack_convolve/libconvolve-0.0.5.tgz Features: - no GUI yet. Send OSC commands directly to load a responsefile. If you use the included test_dssi_convolve.om patch in om-synth (you need latest cvs for this), you can use sclang [supercollider3] like this to send it stuff: a = NetAddr("localhost", 16180); a.sendMsg("/dssi/test/Convolve_0/configure", "rtprio", "0"); a.sendMsg("/dssi/test/Convolve_0/configure", "responsefile", "/home/tapas/sound/ResponseFiles/room/Thick Room.wav"); The included om patch provides stereo input and stereo output. A copy of the stereo input is delayed (by 0.68s which is just the delay introduced by dssi_convolve at a samplerate of 48khz and a partition size of 16384) and mixed back into the output. Both input signals are also mixed together and fed into the single convolution input. The stereo convolution output is mixed into the stereo patch output. While this kinda abuses the convolution to do stuff it shouldn't it still sounds nice :) configure keys understood: "responsefile" value: filename. load the specified responsefile "rtprio" value: the desired SCHED_FIFO prio for the worker thread. when 0 is specified SCHED_OTHER is used. - the convolution runs in a lower prio thread and a huge buffer [default 16384] is used to decouple the convolution size from the hosts periodsize. This introduces 2*partition size frames additional latency which is reported on the "latency" control output. The partition size can be changed by altering the DEFAULT_PARTITION_SIZE in the source code. A configure key for this will be added. Bugs: - loads only in om, not in jack-dssi-host. [any clue?] - might have problems loading mono files. not tested. - SConstruct broken. Use the Makefile - might lock up your boxen. so if this is a problem for you, inspect the source first and fix all bugs ;) - millions more i'm sure. if you find any please let me know :) TODO: - GUI - Different channel versions (mono, 4 channel, 6 channel). This provides always a single input only but the loaded response files may then be mono, stereo, 4-channel or 6-channel. - Realtime mode (where partition size == hosts buffer size -> no additional delay). Need to figure out some DSSI specifics to find out how to discover host buffer size before initial configure call is done (which might load a responsefile and for which the partitioon size needs to be specified) TODO's might take a while due to my limited time atm [studying]. Help appreciated. Drop me a mail. Feedback is most welcome. Regards, Flo P.S.: yes i will remove the audio rate gain input port in the next realease. I don't need it and i figure it might confuse DSSI host apps that try to figure out themselfes how to hook it up. -- Palimm Palimm! http://tapas.affenbande.org
