For example, the cepstrum converts a signal to the frequency domain through Fourier transform, takes the logarithm, then applies another Fourier transform. Source: Internet

In particular, the power cepstrum is often used as a feature vector for representing the human voice and musical signals. Source: Internet

It was in use before the cepstrum. Source: Internet

J.Moir and J.F.Barrett,Proc Royal Society A,Vol.459,2003, pp.2957-2976 Applications The cepstrum can be seen as information about rate of change in the different spectrum bands. Source: Internet

Note that a pure sine wave should not be used to test the cepstrum for its pitch determination from quefrency as a pure sine wave does not contain any harmonics. Source: Internet

Steps in forming cepstrum from time history The complex cepstrum uses the complex logarithm function defined for complex values. Source: Internet
