A command that creates a PowerCepstrogram from every selected Sound.
The sound will first be resampled to twice the value of the Maximum frequency, with the algorithm described at Sound: Resample.... After this, pre-emphasis is applied with the algorithm described at Sound: Pre-emphasize (in-place).... For each analysis window a Gaussian window is applied and the Spectrum is calculated. The Spectrum is then transformed to a PowerCepstrum with the procedure described at Spectrum: To PowerCepstrum. Finally, the values from the PowerCepstrum are stored in the vertical slice of the PowerCepstrogram.
