Hi, I am trying to design a circuit and need some help. What I want to do is take an input audio signal and output it's frequency. How would I go about this without using a fourier transform? Any ideas? Thanks!

What I want to do, is say you play an A note on the piano. The microphone will pick this up, and the circuit will be able to output 440Hz or whatever. That's the basics of it....

A frequency counter could do that, but if it's for tuning purposes you can buy electronic tuners for various instruments - mainly guitars, but presumably for pianos as well?.
A single note on a piano should be OK, obviously a proper tuning system would be better, they usually have switchable filtering built-in to help remove harmonics.
