# cepstralCoefficients

## Description

specifies options using one or more name-value arguments.`coeffs`

= cepstralCoefficients(`S`

,`Name=Value`

)

For example, ```
coeffs =
cepstralCoefficients(S,Rectification="cubic-root")
```

uses cubic-root rectification
to calculate the coefficients.

## Examples

## Input Arguments

## Output Arguments

## Algorithms

Given an auditory spectrogram, the algorithm to extract *N* cepstral
coefficients from each individual spectrum comprises the following steps.

Rectify the spectrum by applying a logarithm, cubic root, or optionally perform no rectification.

Apply the discrete cosine transform (DCT-II) to the rectified spectrum.

Return the first

*N*coefficients from the cepstral representation.

For more information, see [1].
