This MATLAB exercise computes, on a frame-by-frame basis, the real cepstrum of a multi-frame section of a speech signal, and displays the resulting frame-by-frame sequence of real cepstrums in a "waterfall" type of display. To achieve the desired waterfall effect, each real cepstrum is normalized to a peak of 1.0 and offset by a constant from the previous frame, thereby giving the perception of a sequence of flowing real cepstrums. Such waterfall plots are displayed for both the real cepstrum (on one graphics panel) and the STFT and cepstrally smoothed log magnitude spectrums (on another graphics panel). The file '3.15 Cepstrum Waterfall.pdf' provides a User's Guide for this exercise.
