Robust method of fundamental frequency estimation.
I was wondering if any of you know the most robust way to calculate the fundamental frequency of a note across the range of a variety of instruments?
I'm currently working on a matlab program and have tried using the auto-correlation method and the cepstrum method but have found that these both have difficulty in calculating f0 of timbre-rich tones such as those from a piano - particularly in the lower pitch ranges. Does anyone know of a method that is more reliable in these regions or is it necessary that I investigate such complex tones by a different means? From examining a number of the FFTs from these signals it is tempting to just pick the first strongest partial - the complex overtones just seem to confuse the more complicated algorithms, but I realise that this is hardly a
Any suggestion would be greatly appreciated,
Thanks in advance,
