cepstrum

Cepstrum.

Usage:

cepstrum(x)

Function:

Computes the real cepstrum of x.

Result:

A vector containing the cepstrum coefficients.

Usage:

cepstrum(x, n)

Function:

Computes the cepstrum smoothed spectrum of x using the first n coefficients.

Result:

The cepstrum smoothed spectrum. This is the same type as x.

Usage:

cepstrum(x, o, n)

Function:

Computes the cepstrum smoothed spectrum of x using the coefficients o to o+n-1.

Result:

The cepstrum smoothed spectrum. This is the same type as x.

Notes:

x must be a log. amplitude spectrum computed with a radix-2 fft.
