Problem with AnalogIn of Mbed LPC1768

An Audio Signal sent to pin 19 and 20 of mbed lpc1768. How can I check frequency of that Audio signal that came on those two pins ( 19 and 20).

Some guys tried to help me but the problem didn't resolved. It would be great if anyone can help me out.

HI Erik, thanks for posting but this link is quite different from my project. I have already looked at this. What I'm doing is that I have sent an audio to pin19. So I just need to check the frequency of that audio at that point.
