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.
If you put twice the same filter serially, then the gain for each frequency will be squared (double the decibels). This makes the filter steeper (but not narrower).
