I'm not sure, but I think there's no real difference but a different
amplitude (volume) or amplitude of the partials. I think a comparison of a
time-frequency representation of the two waveforms could give a 'scientific'
answer. May be you could use pd to make it (he..I think i will post
something about this later)

Yes, if someone get that, I'd be interested too.
