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.
