execute spectral description function on a spectral frame

Generic function to compute spectral description.

\param o spectral description object as returned by new_aubio_specdesc() \param fftgrain input signal spectrum as computed by aubio_pvoc_do \param desc output vector (one sample long, to send to the peak picking)
