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 290. 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 */
