## pvscent

pvscent — Calculate the spectral centroid of a signal.

## Description

Canculate the spectral centrols of a signal from its discrete Fourier transform.

## Syntax

    kcent pvscent fsig

## Performance

kcent -- the spectral centroid

fsig -- an input pv stream

## Examples

Example 289. Example

    ifftsize = 1024
    iwtype = 1    /* cleaner with hanning window */
    ipos = -0.8  /* to the left of the stereo image */
    iwidth = 20  /* use peaks of 20 points around it */

    a1   soundin "input.wav"

    fsig pvsanal   a1, ifftsize, ifftsize/4, ifftsize, iwtype
    kcen pvscent   fsig
    adm  oscil     32000, kcent, 1
