> Tunelab and Verituner use both FFT as pre anaylsis. Pre-analysis is not pitch determination. The actual tuning is done with different algorithms. I think that's what I said, if I'm not mistaken.

Sample rates have barely a damn thing to do with it. The FFT, by itself, is not capable of a fine enough resolution for tuning, given the noisy signal of a piano tone. > Cybertuner uses counting of cero crossings of filtered signal, needs > also means over a longer time period. > (see patent papers) As do all of the ETDs, as far as I know (filtered or otherwise).

It is? I must be reading a different language that you're writing then. Sorry, I seem to have missed it altogether. Surely my fault, as I'm sure you'd agree. Awaiting enlightenment, Ron N
