Re: Robust method of fundamental frequency estimation.

Dear list,

Just want to draw your attention to a good summary on various
auto-correlation based pitch determination methods,

Arturo Camacho and John G. Harris, "A biological inspired pitch
determination algorithm", Fourth Joint Meeting of ASA and ASJ,
Honolulu, Nov. 2006.

I was wondering if any of you know the most robust way to calculate the

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 reliable

Any suggestion would be greatly appreciated,
Thanks in advance,
