mySample.getSpectrum: incorrect amplitudes
« on: Apr 13th, 2005, 6:01pm »

Apparently, the frequency components visualized by something like  
 
mySample.getSpectrum(L);  // FFT
 
have an amplitude bias that increases going from low to high frequencies. In other words, a sound having a comb of equal amplitude harmonics shows a spectrum with an increasing ramp of harmonics (?!)
Any hints?
