Hi
I have to develop an app that reads microphone input signals (ticks coming from a mechanical applicance) and renders the frequency (less then 3-4 HZ but with decimal part).(sampling at a very low rating sampling 10 ms, for instance).

Is there some sample code or library that could help or give some suggestion? I read about audio library and the straming object but I would like to look at some sample.
thanks in advance
Alex
