if you do so, how are you going to deal with for instance f-modulation
of the fundamental? I'm asking because IIRC all those programs cut the
sampled signal into chunks of 2^n samples regardless of its frequency.
Due to the applied windowing techniques (Hamming, Hanning, Bartlett
etc.) the results are mathematically (more or less) correct but the
displayed spectras are IMHO not very useful in a musical sense.
Granted, many things are detectable by the ear but in my case I'm
still seeking automated help to get even closer to the desired results.
