The amplitude in adjacent channels is averaged out over a given number of (adjacent) channels, without affecting the frequencies of those channels. This broadens, or defocuses, spectral peaks and leads to a noisier or rougher sound. PARAMETERS channels Number of channels over which to average the amplitude. Range: 2 to no. of freq. chans/2. T-V
NOTES The process operates on the spectral envelope and introduces a rougher or noisier sound by averaging the energy over a number of frequency channels. The result may be similar to Exaggerate (widening formants) and Spread.
