This software is basecaly sound analizer. We know that every sound has friquency, so when our motors are running let's say 42000 RPM-friquency is 700 Hz. This software picking up friquency by using Microphone, analize it, removes all extra noizes and mathemticaly recalculate friquency from Hz to RPM.
I played with it yesterday with sound generator on my second PC and it works very accurate. I will test it Saturday on track and see if it works in our aplication as good as in airmodeling.
