AB  - A novel algorithm to perform real-time pitch shifting of quasi-periodic musical tones in such a way as to preserve the apparent spectral envelope was proposed by Lent in 1989. A functional and analytical comparison of that method and most commercial methods of pitch shifting that shift the spectral envelope along with the fundamental frequency is made in this paper. Analytical results show that this method, indeed, attempts to preserve the spectral envelope similarly to frequency domain methods that interpolate between discrete spectral lines and resample the interpolated spectrum at the output fundamental and its harmonics.
