There are several crossovers. Which are you thinking about?

Why not just use three 2nd order filters, and control each of them individually?

djamps commented 2 years ago

@MCUdude hey dude! Any chance to control Nth order 1 channel filters? 2nd order isn't quite enough for my crossovers. Thanks again for your awesome work!

MCUdude commented 2 years ago

@djamps Everything can be controlled, but you'll have to figure out the algorithm yourself, since this library currently doesn't support it. If you don't want to go down that rabbit hole, you can always just connect two 2nd order filters in series.

If it helps anyone, here's a trick to have adjustable 4th order LR crossovers without having to reverse engineer the algo. Just use dcSource() instead of a pot: https://ez.analog.com/dsp/sigmadsp/f/q-a/64925/sure-dsp---crossover-function
