I'm developing a small app which uses aubio to extract the fundamental Frequency of a monophonic guitarsignal to drive a set of wavetable synths. It works quite well and I'll put up on the net when I have the time.
But I would like to extract the fundamentals of a polyphonic signal. Does anyone know of a lib which does this in realtime? Or at least a state of the art paper I could implement?
thanx,
Gerald
