My bad, no it doesn't; pvsbufread uses i-rate limits, no k-rate changing I'm afraid. It seems like it would be useful to be able to write bin expressions, so to use conditionals or even arithmetic based on amplitude or frequency values per bin per frame. So something like: fhighpass pvsinit isize, iolap, iwinsize, iwintype fbandpass pvsinit isize, iolap, iwinsize, iwintype fhighpass.amp bin= (fin.freq > 3000 ? fin.amp : 0) fbandpass.amp bin= (fhighpass.freq < 10000 ? fhighpass.amp : 0) -Chuckk -- http://www.badmuthahubbard.com
