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.
