I got Gen when it came out. Haven't used it all.

One thing I'd like to try is sample accurate peak (or rising edge?) detection from 3 independent sources to estimate position of impact on a surface.

I've wanted to try this for years but never got around to it - can anyone give me any pointers as to where to start?

I should add why I put this in the Gen forum. The actual detection wouldn't necessarily have to happen in gen but once detected, I'd like to get at as precise a point as possible within the buffer of samples as to when the onset occurred....for maximum resolution/accuracy.
