Detailed Description
Compute the generalized autocorrelation of input window.
Computes the generalized autocorrelation (with optional magnitude compression) using the Fast Fourier Transform (FFT).
Controls:
- mrs_bool/aliasedOutput [w] : by default, this control is set to true and the output of AutoCorrelation will be an alised time domain signal (as used by the original Marsyas0.1 code implemented by George Tzanetakis - MUST CHECK IF THIS MAKES SENSE!). Setting this control to false, the FFTs will be computed using the next power of 2 of the inSamples*2+1, which avoids alising in the iFFT step. In this mode, only the first inSamples of the autocorrleation function will be output (since the remaining ones are mirrored versions or zero valued).
- mrs_bool/setr0to1" [w]: if set to true, the output will be normalized so that r_xx(0) = 1 Had to use a weird name because there already was a normalize control [AL]
