[sdiy] Ray tracing hardware for audio simulation

[Mike Bryant]

I'd be surprised if anybody is going to use audio ray-tracing in a live environment.   It would definitely have uses of cancelling the auditorium reflections, but the time delay will just confuse the musicians and singers.

But the whole GPU DSP processing has 1000s of uses.

I'll certainly be interested to see what kind of bounds they achieve at such time as there's a realtime audio ray-tracing product on the market.
