https://www.airwindows.com/biquadnonlin/   / airwindows   A biquad filter is a very basic piece of typical DAW EQs. If you were going to think of the most ordinary, normal, non-special digital EQ that would sound like every other digital EQ, you're probably going to be stacking up biquad filters. It is the most boring of digital filters, at least ones that are kind of flexible. Let's break it! BiquadNonLin takes the traditional biquad filter, complete with cutoff and Q factor, and applies the same technique used in Capacitor2. That was the one where I read about Murata ceramic capacitors showing striking variations in value, based upon how much voltage pressure was against them. Which is not to say all capacitors do that… but knowing this has happened in the real world suggests that it's an avenue to pursue. And so, Capacitor2 brought in this interesting nonlinearity based on real-world stuff, like a (in fact literally a) frequency modulation… and then it sat for a while. Because how would you even apply that to a carefully worked out algorithm like a biquad? The answer is 'you just do'. Does it produce a clean result? Nope. You can break things pretty thoroughly, especially up near the Nyquist frequency. But you can apply less… I find 0.5 tends to work quite well… and you can get the same kind of nonlinearity. It's just that this time, you can do it on a steep, resonant filter, and get that more analog texture on something that's otherwise very controllable. I'm looking to use this on many things: I think it'll make for a better-sounding distributed ultrasonic filter, and I'd also like to make a multistage version to use as the guts of a future ConsoleSL… because it should work more like a steeper but less vibey filter, except with the analogification. Anyway, here's BiquadNonLin: one biquad filter, lightly broken for your sonic pleasure. Type at 0 is a lowpass, Type at 1 is a bandpass. The biquad tended to explode when I tried to make it do highpasses or notches, but it turned out I could just make the dry/wet an Inv/Wet control, so that means you just use Inv instead, and Type at 0 becomes the highpass (it's subtracted) and Type at 1 is the notch. If you have a hard time hearing the nonlinearity, setting it to highpass and sweeping it up at high NonLin should make it real obvious.
