Hi *, I've been working on a lightweigth OSC API for the last couple of days and I'd appreiciate some comments - it works as it is, but it needs some work and the API isn't final so please dont integrate it into any projects yet. Its quite limited: * only basic OSC types (int, float, string, blob), but adding more is easy * no unix-domain sockets (just UDP) * no bundles * only accepts typed messages (unless you handle the packet parsing yourself) On the upside you can send an OSC message in 2 lines of C using a fprintf style function and you can setup a serverthread with polymorhism/automatic typechecking and callbacks (JACK stylee) very easily. You can also use bits of the API selectivly if you want to mange bits of the OSC lifecycle yourself, eg. handle raw OSC by hand or provide your own thread. Theres an example program that uses it here: http://plugin.org.uk/liblo/liblo/src/testlo.c and you can get the tarball here: http://plugin.org.uk/liblo/ Comments on the API style, testing and offers of help greatfully received. - Steve

[call for mirrors] if you have a host with good internet connection and are willing to donate some bandwidth, please contact me off-list. either you provide an icecast2 server yourself, or else i will need shell access to build one (though not root). the distribution needs to be recent, or else building icecast2 is problematic. for the webcam, we'll need a couple http servers as well. i thought about round-robin dns, but a friend just pointed out a master server with some php code that will produce a different link each time it is called is probably easier. so all you have to do is pull an image every couple seconds, make it available somewhere and send me the url. yours, joern

[linux-audio-dev] alsa mixer apps

by Florian Schmidt

Hi, i heard on the #alsa irc channel, that some graphical mixer apps don't treat the alsa mixer [ctl] devices not right. For example on a cs46xx alsamixergui does not allow toggling capture on the "Capture" channel. This would be required and is no problem with alsamixergui. I wonder if other mixers have problems like this. This can be confusing like Hell to newbies.. -- http://www.soundclick.com/bands/9/florianschmidt.htm http://www.arted.biz/mista.tapas

[linux-audio-dev] Project: modular synth editor

by Juhana Sadeharju

Hello. I feel we should write a modular synth editor from scratch. I have checked many existing systems but none is good enough. The editor would just be the editor. There would not be anything related to audio processing. Developers could use the editor in any project, audio or not. The editor would handle GUIs such as in AlsaModularSynth, Arts, Galan, Gdam, Glame, NMEdit, PD, Quasimodo, SpiralSynthModular. Also we should have an API and a script in the system. I can set up a project folder to our ftp site, ftp.funet.fi, for resources (manuals and screenshots of existing systems, research papers). Coding should happen in some CVS site. Any comments? Regards, Juhana

[linux-audio-dev] ANN: Specimen Version 0.0.3 Released

by Pete Bessman

Guess what? ...*chirp*...*chirp*... Right, well... Specimen is midi controlled audio sampler for GNU/Linux systems, and this is a new release of it. I'm justifying this on the inclusion of velocity sensitivity, cuts, and proof-of-concept (read: crappy) pitch scaling. You can download the newest tarball, check out the new screenshot, and listen to the _fearsome_might_ of Specimen at www.gazuga.net. [pb]

[linux-audio-dev] oprofile, redhat and CONFIG_PREEMPT

by Michael Ost

Hi, all. We want to run oprofile on our redhat 8 based system. It looks like great technology, but an oprofile FAQ says it doesn't work on redhat 8 systems. The FAQ recommends downloading a redhat's oprofile rpm, which we did. But that is configured not to work with a CONFIG_PREEMPT kernel. Our kernel is CONFIG_PREEMPT patched for increased audio performance. Yikes! Has anyone run in to this problem and found a clever solution? An alternate profiler that works? Will we get meaningful results if we rebuild the kernel with CONFIG_PREEMPT turned off? Or perhaps we can run it with CONFIG_PREEMPT on and see what happens? Cheers... =================================== Michael Ost, Software Architect Muse Research, Inc. most(a)museresearch.com mo

Yes, I don't have a problem getting support from them since I pay for it. > Can you get Windows at a lower price, if you don't need support and > stuff...? ;-) Yep, cheaper than Red Hat Enterprise...

What would be that "something"? Not much? I recently proposed that GDK/GTK should be extended with OpenGL widgets so that there are no two distinct systems a developer have to use. It simply does not work if a developer has to write, e.g. menu routines from scratch. Converting a large GTK application to use OpenGL widgets would then be an easy task. Regards, Juhana
