@ChainsawNbud nope, and its not too complicated actually. The dopplereffect was already used in ww II radars (only with radar waves instead of sound) to filter (moving) planes from (floating / stationary) chaffs. this will get interesting if more than one soundwave is running though.

I have a special interface for word processing and simple drawing that responds exactly to the movements of my hand and produces and instant hard copy. Not only that, it's wireless and completely mobile.
