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.

Hi, is there any implementation of filters in Pd with audio rate
cutoff
frequency?
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...)
