The frequency inlets of [lop~] and [hip~] don't take signals, that's why you get clicks. You have to implement the filters yourself using [rpole~], [rzero~], [cpole~] and [czero~]. You can read the theory here http://msp.ucsd.edu/techniques/latest/book-html/node139.html

Or you can go to Pd's forum and check some post from Maelstorm (administrator). His posting signature is his library of abstractions that include all kinds of filters driven by signals too.

Hello is there a way to avoid clicks and pops coming out when moving the frequency/bandwith knobs of the lowpass and hipass filters of the pd library?

line~ and sig~ lop are not working because the knobs are not controlling an audio signal.

Thanks in advance

Luca
