Still tinkering. But it is looking good so far
I have been working on acoustical diagnostic processes for a little while. My direction is on seizing and harnessing different signal capturing and transmission of vibrations and more direct analysis as compared to a program tic analysis like this app features. In my approach I am acquiring signals from the engine, to include engine rpm from cylinder 1 spark plug during events then visually looking for correlating events from concurrent signals being recorded. It I a more raw and base way of doing what this iPhone app does for me so eloquently. I can see how this app can be extremely useful in my diagnostic approaches. Very clever app.
