[linux-audio-dev] references

by Kevin Sookocheff

Hello everyone, I'm looking to lend a hand at an audio project. I'm not a new programmer but I'm new to audio programming. Is there any good references out there to help me get up to speed? How about any essential libraries, system code that I should learn? Thanks a bunch, Kevin

[linux-audio-dev] Beginner question about ring buffer and block processing

by David Cournapeau

Hi folks, I try to get my head around a basic problem, and I don't manage to get around it: how to adapt to variable sized blocks of samples given by a ladspa or jack host/server to an existing, fixed length block processing algorithm, for example a N points fft. AFAIK, the ring buffer is the standart tool to solve this problem, but I don't understand how this helps ? I tried to read the source of jamin, which implements this kind of scheme in io.c, but I couldn't manage to get the whole thing. I would be glad to hear any hint about the right way to use ringbuffer for this task, cheers, David

That was the problem which did lead me to develop the system a few year ago. Any hardware can be used in the system for lowest latencies.

Hi ryan, All these bugs and mistakes comes from an old release of wavemixer (0.2) It should be ok if you install the latest package (0.3) available here : http://wavemixer.sourceforge.net/index.php?lang=us&section=download Regards, Raoul.

Re: [linux-audio-dev] LADSPA Issues

I think that would be a non-standard extension of the current practice and wouldn't be understood by current parsers.

[linux-audio-dev] [ANN] LinuxSampler 0.3.1

by Christian Schoenebeck

LinuxSampler [1] is a modular, streaming capable sampler. It was designed decoupled from any user interface, that is as sampler backend which can be controlled via network connection from an arbitrary place, using a custom, ASCII based protocol called LSCP [2]. [1] http://www.linuxsampler.org [2] http://www.linuxsampler.org/documentation.html Focus of this first release was an adequate support of the Gigasampler format, including experimental support for the new Gigasampler v3 format. For a complete list what is already covered and what is not, check the features site [3]. [3] http://www.linuxsampler.org/features.html Planned next: * strong synthesis optimizations * support for further sampler formats * instrument database system * implementation of further control interfaces like OSC [4] * SMP and network cluster support * as ports to other OSs are already on the pipe, maybe a new name :P You might want to use QSampler [5] as convenient graphical frontend to LinuxSampler. You can get everything from the downloads site [6].
