Airwindows Biquad2: Mac/Windows/Linux AU/VST

1 min read

This time, it’s time for the impossible!

As in, there was a reason nobody was doing sweepable, ‘synthy’ biquad filters…

Turns out it simply doesn’t work. One uses a different type, like state variable filters, for the synthy stuff. The reason is that, while biquads can sound pretty great (especially implemented like I do ’em), they fundamentally can’t cope with changing the filter coefficients mid-calculation. They flip out: you’ll hear some of that, especially at the frequency extremes. Low Q makes low frequency motions flip out, and high Q (and boy do I have a high Q for you this time) makes ultra-high frequency motions flip out in a really wild. glitchy way.

So obviously I gave up.

  1. If it didn’t get silly, it wouldn’t be fun to mess with 🙂
    Edit: I’m digging the plugin kit concept! I’ve been turning to the spreadsheet shared on the Facebook group for keeping the plugin list straight in my head, but I like the kit idea even more!
