Hi Mimo,
I have put online the beginngs of a concept paper for an audio program I have been wanting to write for quite a while now. I wondered whether you could give me some feedback on it and share some of your experiences with me. A while ago I decided to call this *mux* where the name stands for nothing in particular. I have tested a couple of similiar audio apps for linux recently, and then toyed around with libraries I found on the net. I might be reinventing the wheel once more, but that's up for discussion.. The paper is work in progress, I'm hoping to add to it tomorrow night.
Looking forward to hear back from you and thanks for any input..
PS.: the paper is here http://mimo.gn.apc.org/mux/
[snip] Another thing: I don't agree with the assessment in your paper that jack is heavy-weight - and I think jack is much more natural fit to your application as jackd has xrun detection, already provides means to set a lower samplerate and increase period size if your system can't put up with the load. IMHO jack is the way to go if your target platform is only Linux (or OSX & BSD), otherwise the cross-platform PortAudio may be more appropriate.
I'll chime in here. I've been testing Csound5 quite a lot lately, it supports PortAudio (as well as ALSA and JACK) and PortMIDI. Frankly, I'm not impressed with default realtime performance under PortAudio. I can improve performance with some judicious buffer tweaks, but the native ALSA driver is much better.
I also agree with Walco re: JACK weight.
Nevertheless, it's Linux, innit ? So you can do what you like... :)
Btw, mimo: Have you tried using Buzz under Linux ? I've had it working quite nicely, it's a very impressive program, lots of fun. A native Buzz would be most welcome.
Best,
dp
