identifiying frequencies from a signal

August 28, 2006 | 6:32 am

i’ve been looking through all the tutorials but i can’t figure out how to get the freq from an audio in signal.

for example, if a piano sample is played, i want to be able to identify the freq. so if you hit A above middle C it should display the number 440.

can anyone give me any tips?

Thanks, Ed

You can find them on the net, I guess.

It would be great though if someone made a neat msp patch version of this. I’d probably pay more for a bundle of this kind of abstractions than for a bundle of externals with the same functionality. Hmm, actually, that sounds nice.. I might just start that project myself.
