My recommendation, as having it tried out once, the more for people with a little
more basically acoustic (as related to physics, not as opposed to ea) interest in
music, though I am not (at all) convinced as to the next paragraph...

-- for, as mentioned (privately), the idea of the spectrographical representations
exactly corresponding to the respective auditory impression does get the more
obsolete as one does know a little bit about how to make spectral components visually
appear and disappear...
As to the FFT in general, as pointed out by Roald Baudoux, I think this might be due
to some rather common view being prevailing that FFT representations are more likely
to being immediately and "intuitively" comprehensible (which I would support).
