Hi, you mean you call the setup after every sample? That won't work as iir filters need to settle for roughly 1/cutoff_freq. You could call the parameter setup() once in a while but there will always be a settling time.
Best approach is probably to create a filter bank with different filters and letting them all filter all the time and then switch between them.

Oh yeah thanks! I created 100 Bandstop filters spread over the spectrum and select the right one! It isn't perfect because sometimes is crackles when it switches between the filters, but its enough for my purpose. (I guess I could fix this by fading between them)
Thanks again!
