I've noticed this, too. It sounds like the noise you'd get if you were just using [line] to change the frequency. My guess is the cutoff frequency is being sampled and held at the block boundaries. If you put these objects in a patch with [block~ 1], it goes away.<div>

hi,<br>
<br>
just a quick question,<br>
is it normal or somewhat on purpose that all versions of low pass<br>
filters in iemlib (from lp2 - lp10 and cheb, butt, bess and crit)<br>
exhibit slight high pitched jitter when cutoff frequency is being<br>
dynamicly changed? is it a nature of such filter or just a type of<br>
implementation that somewhat doesn't take care of interpolation (if<br>
interpolation is a problem at all)?<br>
<br>
any thoughts welcome...<br>
<br>
is there a way i could avoid that jitter with these filters?<br>
<br>
is there some other high-pole low pass filter in some other library i<br>
could use?<br>
<br>
sure, i can always use series of [lop~] ..<br>
<br>
<br>
<br>
best, luka<br>
