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

		
ifftsize = 1024  
iwtype = 1    /* cleaner with hanning window */

a1   soundin "input.wav"

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