Many engines claim it, and I know blitz3d says it does 3d audio (although I haven't used it as I don't have surround speakers)
Is it just positional sounds ie the sound seems to come from its position in 3d space?
Or do any of them actually have interactions with the environment so that you can get echoes down halls, sound dampening of objects colliding with carpet instead of say a wooden floor, doppler shifts for moving sound sources, interference effects for inphase/out of phase sound wave forms.
