Need a method to change filter coefficients #155

Closed ghost closed 2 years ago

You can't assign a new filter it pops, I can't get to the biquad_block to modify the coefficients. Needs some method to get them or modify it while it is running without popping.

I am modifying it to get the expression_filter as it is protected

Hah, I got the expression but I have no idea how to get it into an expression_biquad at all.

I realized, I have written a bunch of biquad. Well, Kfr already calculates the coefficients which is the hard part, so I can just use Kfr to calculate the coefficients and use a simpler biquad to compute the filter instead.

Haha, works great, plus now I can use the ZPK and SOS too to make anything
