I'm building an open source 3D networked game framework (who isn't?).
As part of that, I'd like to include 3D audio support. I've seen irrKlang and FMOD, but this game framework is free and open source. So I need an audio library that is free (BSD or MIT licenses) or at least GPL'd.
I found audiere, which looked okay: http://audiere.sourceforge.net/documentation.php
However, it looks like the last update was in 2006 (!) and I noticed I had to tweak the source to get it to compile under newer GCC compilers.
Is audiere still used/supported? Are there other open source (free) audio libraries that people recommend? I could add my own 3D layer if needed, but obviously I'd need basic support for multiple sound streams, with per-stream control over volume and panning.
I'd recommend OpenAL Soft over OpenAL since it will work with full capabilities in Linux and Mac as well as Windows. It's LGPL which is better than a straight GPL and has the capabilities you requested.
Thanks for the pointers! For now I'll used audiere. I felt better when I saw there had been recent updates (just no recent releases). I was able to build simple 3D support on top of audiere relatively quickly.
I've put it all here for now, in case anyone is interested: https://sourceforge.net/projects/wave-audio/
If I run into problems with audiere, I'll switch to OpenAL (or OpenAL Soft).
