Thanks for that info :)

Also, is there any way i can create a GUI for the guitar tuning application?? or any way that ChucK programs can communicate with either C++ or Java codes?

Don't forget zerox for zero crossing detection. Crude pitch detection
can be done this way. It isn't as potentially accurate as the method
Hans is describing but it is much faster to test.
