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
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
