[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

[linux-audio-dev] help on echo cancellation

by BINI A A

hi there we are trying to use linphone for a project,i dont know whether it supports echo cancellation or not,i think it is not there in linphone. can we integrate the echocancellation module given at http://home.arcor.de/andreadrian/echo_cancel/draft-aec-03.txt to the linphone..or can we seperate out the echo cancellation module in Speex and use it with linphone? which will be better and easier? thanks bini --------------------------------------------------------------------------- "This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.

[linux-audio-dev] [ANN] First official release of JAPA - Perceptual Analyser

by fons adriaensen

Hello all, The first official release (0.1.1) of JAPA is now available at <http://users.skynet.be/solaris/linuxaudio> Changes w.r.t. the 0.0.1-alpha release: - now uses anti-aliased fonts (via Xft/fontconfig) - added /etc/japa.conf - added 80dB range - added 440Hz log scale - some bugfixes Many thanks to the alpha testers, in particular Lukas Erni. JAPA is a 'perceptual' or 'psychoacoustic' audio spectrum analyser. This means that the filters that are used to analyse the spectrum have bandwidths that are neither constant (as in JAAA), nor proportional to the center frequency (as in a 1/3 octave band analyser), but tuned to human perception. With the default settings, JAPA uses a filter set that closely follows the Bark scale. -- FA

[linux-audio-dev] High res timers

by Lee Revell

Hey, In case you didn't know, the high res timers patch (which Ingo calls "a critical piece of RT infrastructure") has been merged into Ingo's RT preempt patch. So I think it's safe to assume it will be going in the mainline kernel too. This is great news for Linux audio as sub HZ timers enable lots of cool features. We will be able to send a MIDI clock that is as solid as you get from dedicated hardware. Lee
