[linux-audio-dev] crossplatform atomics

by Maarten de Boer

Hello, I am looking for a cross-platform implementation of an atomic integer. Under Linux, a build an c++ class "atomic" around asm/atomic.h, (which I can use as if it where an int), but I'd like to have a solution that also works on Windows XP and Mac OS X. Thanks for any suggestions, Maarten

[linux-audio-dev] LV2 library API

by Dave Robillard

Hi all, I've been working on a host library for LV2 plugins. It's at the point where everything is working (LV2 plugins are working in Om right now), so I'd like some feedback on the API from anyone who's interested before it gets too entrenched. The primary design goal is to be as simple and terse as possible for the host author, so if you would prefer something was different let me know. A simple (working) Jack host: http://www.scs.carleton.ca/~drobilla/files/slv2_jack_host.c Doxygen documentation: http://www.scs.carleton.ca/~drobilla/files/libslv2_doc/ (Anything having to do with SLV2Property is still hairy, everything else is fair game). And no, you can't have the code yet. Steve would hang me. :) Cheers, -DR-

[linux-audio-dev] Abandoned Csound tracker looking for maintainer

by Lars Luthman

A couple of years ago I started writing a tracker-like GUI program to control Csound, but then I mostly lost interest in Csound and forgot about it. It's a bit like Buzz or Psycle or Octal in that it has a built-in "modular synth" where you connect Csound instruments and a traditional tracker-style pattern editor. It probably doesn't work with recent Csound versions and probably doesn't even build with recent compilers and libraries, and I'm not going to hack any more on it. But if anyone is interested in taking over, the source and other things can be found here: http://keso-project.sourceforge.net/ I'd be happy to hand over the SF project if anyone is interested. -- Lars Luthman - please encrypt any email sent to me if possible PGP key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x04C77E2E Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-dev] Midi Clock

by krampenschiesser＠freenet.de

Hi I'm currently writing on a loop based midi sequencer. My problem is that I want to get Hardware synced via midi clock. I've read that the midi-clock signal is send 24 times in a quarter note. My sequencer is network based. So there is one time-server which sends a tcp packet with every 256 note. But when I want it to send the midi-clock signal it would be send every 2+2/3 note. Which is not possible. Do you see any solution? -- A sine curve goes off to infinity, or at least the end of the blackboard. -- Prof. Steiner

[linux-audio-dev] precise event timer examples (HPET?)

by Alex

Does anyone have any examples that use HPET (or any other high resolution event) timers? I've built HPET support into my kernel but I cannot figure out how to compile the example given in the documentation : /usr/src/linux-2.6.12/Documentation/hpet.txt I have searched the web and I cannot quite figure out how people use these. I'd like to have micro-second precision and I'm wondering if there is a better way then polling the time of day? Thanks, Alex Norman

[linux-audio-dev] Extreme time-stretching sofware v.0.0.2

by Paul

Hi. I released today the second version of the extreme-time-stretching software. It's here: http://hypermammut.sourceforge.net/src/paulstretch/ News: - Added a graphical user interface (requires wxWidgets). Now you can control the FFT size (buffer size) too. Also, you can use this program as a very interesting effect if you make FFT size large (even if the stretch parameter is close to 1) - Added Ogg Vorbis support for output (requires ogg vorbis libraries) - Added an "optimize" option to the FFT size to make it power of 2 or 3 for speedups (afaik the fftw library is optimised for these kinds of buffers). The disavantage is that the stretch value is now quantised (if you don't like this, you can disable the optimize checkbox). P.S. For now, there is no available resource checking (I mean if your disk is full or the buffer size is too large, the program will crash) Paul __________________________________________________ Do You Yahoo!?

[linux-audio-dev] Extreme time-stretching sofware

by Paul

Hi. I rewrote the experimental time-stretching software (discussed in linux-audio-user mailinglist in "How can I time-stretch the sound like this" topic ) and I put it here: http://hypermammut.sourceforge.net/src/paulstretch/ Please listen to audio examples here (with 20x stretching): http://hypermammut.sourceforge.net/src/paulstretch/example/ The algorithm is simple and it's described into the readme.txt from the archive. There is room for improovements to avoid over-smoothing (I wrote in readme.txt how I think that is possible to do). Please tell me your opinion about it.

[linux-audio-dev] [PATCH] aubio 0.3.0 makes abionotes work *) with jack & alsa_seq

by karsten wiese

hi attached patch includes MEMSET fixlet from yesterday. it adds err subtracts pthread_* calls from aubio_midi_direct_output(). those did block here. and aren't anyhow needed in aubio_midi_direct_output(), i think. karsten *) here ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de
