#FFT Features

##Description The FFTFeatures class computes a number of features from an FFT signal. These features can include:

  • the frequency bin that contains the frequency with maximum magnitude value
  • the ratio between the maximum magnitude and the sum of all the magnitude values *the centroid of the FFT magnitude values *the top N frequency values

The FFT class is part of the Feature Extraction Modules.
