Similar to the ambisonics questions, I'm wondering if anyone has done any work on an 8 channel surround patch. I'm looking for something that works in a polar coordinate system. The idea is that a sound is distributed amongst speakers based on it's angle, and distance from the center of the speaker arrangement. This is not simply a pan 360 degrees around 8 channels. That's easy. This is more like spatializing an object inside a space by giving an angle (0 for front of the room) and radius (0 for center an 1 for edge of speaker perimeter). The ability to specify the amount of speakers for use with other listening environments is also a requirement.
Any ides on where to start? Right now I assume that all speakers are distributed evenly around a circular perimeter. I'm using a cosine panning law for panning around a perimeter but am lost on how to best go about spatializing inside the perimeter. If anyone is willing to offer up a patch I could tinker with, I'd really appreciate it.
Thanks, Phil
