I'm having the same problem. It's like a zipper noise that you can't avoid
no matter what interpolation time you set. If you set it to 150 ms or above
it works. But how can you have fast attacks like that?
At the moment I am changing interpolation times after the initial attack
time of the envelope generator. So I got rid of most of it. But still some
noise during the attack period.
Moog filter has audio ins.
the biquad object from nusmuk audio (bq~) does also have audio inlet for filter
coef.
since it's a biquad, you can shape your filter...

That one works a lot better but has a rather
fixed, predefined (but good) sound.

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