Audio rendering taking into account the 3d scene

Hi,

I'm looking for a solution to do proper audio rendering, i.e. something that takes into account the 3d environment of the audio source and audio receiver (mostly walls (including their thickness and perhaps material). I found some pages on RESound (2), but it seems to be only a research project.

Is there a nice library to do audio *properly*? I think it's needed for VR. Unity3d doesn't seem to offer anything in that regard.

    well, there is GSound, which uses ray tracing to determine audio path. i dont know much about the audio field, but the downloadable demo is really convincing!

    real audio could add a lot to the experience.

    ps.:
    this lib uses the CPU, i wonder if this could be efficiently run on a gpu (maybe on an integrated GPU that doesnt have a job anyways)

    Fmod supports 3d geometry affecting the sound.

    Both look interesting, are free for non-commercial use and fmod even has a Unity plugin. Thanks!
