I'm finally implemented 3D positional functionality into my audio system, rather primatively albeit. The problem is, I derieved the formulae myself, for the most part, its great, gets the job done, but its a touch, well, not right sometimes. Each channel of audio is basically a microphone with a position and a direction in the 3D world. To work out the attenuation based on direction, its pretty much a dot product between the direction of the sound, and the direction of the microphone. This gives me reasonable results, but I was wondering if anyone knows of any good books, or even websites that'll point me in a better direction? I've had little luck with google this time, sadly enough. Thanks.

Been there and done that. I'm doing this as a learning exercise, and the fact that I struggled getting any DSP to work how I wanted in OpenAL. I prefer understanding how things work before I go and just blindly use them.
