I want to build a very steep, narrow notch filter. Any suggestions as to how to do this? I've played with [notch] and [biquad~] but haven't seem to get the results I am looking for.
ive had good results with biquad~ using rbj. you have to chain several of them together on the same frequency though, as each one only takes out 6db or something. its worked quite well to get ridxn of the 19khz stereo tone from FM broadcasts, unwanted resonant frequencies etc.
another good option is FFT
