Does anyone know some good algorithms for determining a) the presence or absence of harmonics in a signal (non-speech), and b) whether the signal is discrete or rhythmic (repetitive)? I can imagine that these two questions are related, one is in the frequency domain and one in the time domain. I have fooled around with autocorrelations, but want to be able to extract a number that would capture the amount of either harmonic or rhythmic structure in a signal. PS if you have Matlab code, all the better. Many thanks, Brian Gygi Indiana University
