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/ Have fun* Niklas
