NOTE: this function is now available from the IoSR Matlab Toolbox as iosr.dsp.stft and iosr.dsp.istft.
Calculate the short-time Fourier transform and its inverse for a signal. The STFT is normalised such that it fulfills the constant overlap-add (COLA) criterion. Fulfilling the criterion is useful when resynthesising the signal using the ISTFT, as the magnitude of the output of the ISTFT will be retained.
