Albert Graef sagte:
Alternatively, is there any other spectrum estimation
method which gives
a reasonably good approximation of the main partials of a
(pseudo-)periodic signal (FFT is too bad in the lower
frequencies)? Does
You might want to have a closer look at linear prediction (LPC). It is
very good at displaying only the main peaks and does not suffer from a
coarse resolution at lower frequencies, because you basically get a
continuous filter back)
You can play around with comparing LPC and FFT results at different
settings by using my software :-) http://sonasound.sf.net/
