I remember there were many filter abstractions based on biquad~s. I thought they were in the iemabs directory, but I can't find them. With the biquad based filters, you can put them in a [block~ 1] abstraction and modify the cutoff/center frequency at audio rate.

hello,
i know there is a lot's of filter externals available for pd, but i'd like to use some using rpole~ / cpole~ etc. my main motiviations are :
- i don't like using externals
- this object allow an audio control of the cutoff frequency
as there is not a lot's of exemples, i'd like to know if anyone used this objects to make good filter abstraction. or anyone have references in order to disign filter? (i'm looking for a low pass resonant filter by exemple)
thanks Cyrille
