Hi there. I’ve cascaded 8 Butterworth filters to get -96db/oct.
The roll off frequency shifts both cascaded LRiley and butterwotrth. What do you suggest about it? Inserting a peak filter around cut frequency (if so, how the q and gain should be calculated for it) or cascading filters with calculated Q values for each one, using makeHighpass or makeLowpass methods, or someething else?
