Well, as a "human" voice, this is an OK one. Peace of cambraiĬepstral by Cepstral LLC.

Cepstrum analysis is a nonlinear signal processing technique with a variety of applications in areas such as speech and image processing. The complex cepstrum of a sequence x is calculated by finding the complex natural logarithm of the Fourier transform of xthen the inverse Fourier transform of the resulting sequence. The toolbox function cceps performs this operation, estimating the complex cepstrum for an input sequence. It returns a real sequence the same size as the input sequence. Try using cceps in an echo detection application. First, create a 45 Hz sine wave sampled at Hz. Ichra lahoreĪdd an echo of the signal, with half the amplitude, 0. The real cepstrum of a signal xsometimes called simply the cepstrum, is calculated by determining the natural logarithm of magnitude of the Fourier transform of xthen obtaining the inverse Fourier transform of the resulting sequence. The toolbox function rceps performs this operation, returning the real cepstrum for a sequence. The returned sequence is a real-valued vector the same size as the input vector. The rceps function also returns a unique minimum-phase sequence that has the same real cepstrum as the input. The following example shows that one output of rceps is a unique minimum-phase sequence with the same real cepstrum as x.
