Hi, is there any implementation of filters in Pd with audio rate cutoff frequency? The filters in Super Collider provide this and it would be very handy to have it also in Pd.
Thanks, Kosmas
Hey, in pd vanilla there's vcf~ and bob~. Have a look at iemlib for some more ;-)

I have packed Mike-Moser Booth's [filtercoeff.mmb~] and [biquad.mmb~] abstractions into one vanilla abstraction which eliminates the use of [expr~]. Both [omniFilter_abs~] and [multiFilter_abs~] support eight filter types: lowpass, highpass, bandpass, allpass, lowshelf, peaknotch, highshelf, and resonant.
All their inlets take signals.
You can find here here https://github.com/alexdrymonitis/filter_abstractions

You mean with vanilla objects? Or are you also looking for externals?
I have a bunch of filters in my "ELSE" library and they all take signal input. Actuyally, the whole library is strongly oriented towards signal control, like also impulses as triggers, signal gates, etc... and this is much like Super Collider was designed as well. I also ported many things from Super Collider like virtually all their chaotic generators - so if you wanna check it out, see https://github.com/porres/pd-else/blob/v1.0-beta17/README.md for a list of objects, and here for the latest releases: https://github.com/porres/pd-else/releases (also available in Pd via "Help"=>"Find Externals".

Forgive me if this has been posted already, but what about [vcf~] which has a lowpass and bandpass output and a signal inlet for cutoff?

yup, that and bob~ have been mentioned. I could add other lower level options like the raw filters [rpole~]/[rzero~]/etc) and [fexpr~], but that requires a deeper knowledge on how to use them. And on that topic, let me show off my advanced filters section in my Live electronics Tutorial, which presents this knowledge: https://github.com/porres/Live-Electronic-Music-Tutorial/tree/v-1.0beta-7/Vo...)

For time-variant one-pole LP and HP, I use these coefficients with rpole~: http://www.earlevel.com/main/2012/12/15/a-one-pole-filter/.
They have a fairly accurate response for basically the whole spectrum. Below .01Hz or so, you need double precision.

According to the author of the book below, the zero-delay feedback design is particularly good for time-variant applications.
So have a look at the filters here: https://www.discodsp.net/VAFilterDesign_2.1.0.pdf.
