No way man, got an oscilloscope then, put the 'scope in X-Y mode, and take your signal, and that goes on one axis, then a pure sine on the other. If you know the freq of the pure sine, you have a VERY accurate way of measuring freq. And you can see how close to a pure since the horn's putting out.
But mainly, it LOOKS COOL!
