Hi, I am looking for a way to find the frequency currently being played on the microphone. I am trying to make a guitar tuner application for when the guitar is plugged directly to the microphone input. This should be a fairly easy thing to but i dont really have an idea where to start. After messing around with some Direct Sound examples for about an hour I didnt find a solution. Do does anyone have any ideas?

Thanks,
Jeff Hockema
