hi,

I'm struggling to complete a 2nd order allpass filter in gen. Idk what's wrong, probably something with calculating the coefficents. If somebody would be willing to help, I'd appreciate it a lot!!

I figured what i'm missing. I didn't calculate c. I thought I could just use the normal number between -1 and 1 like in a 1st order. Solving it now.
