This is great to see! I have a side project to port the old Peep Network Auralizer to a web based project[1] and the code already has the concept of mono sounds originating at different points in a 3D space, so this should be relatively straightforward to integrate. I was aiming for Android/iPhone compatibility though; is there any multichannel audio support on mobile yet or would I need a fallback?
