Well, this is clear to me - but what size do you use? My use of the term
'window' may be unclear in this context: I meant the window size for the
fft, i.e. how many samples are used in one fft run? I take from your

only if) it doesn't start at zero: The ratios of the frequency axis'
labelings is not constant, they grow with larger values.
