# Baxandall is a killer general-purpose EQ.

Baxandall starts with a two-band filter that, zeroed out, subtracts an inverse lowpass from a lowpass and gives you bit-identical, perfectly transparent sound. That’s if you’re being subtle. If you boost or cut, lows or highs, it gives you the gentle broad boosts you expect, centered on the vital midrange. As you get more intense with the boosting, it gets more extreme, to where if you’re doing double boosts to get an intense exaggerated sound, a mids notch will naturally develop to accentuate the boosting. The whole voicing shifts to accomodate what you want to do with it, and you can play bass against treble or vice versa to get really wild voicings, such as for extreme EQ treatments (in terms of lows or highs)… but using the same natural Airwindows Baxandall tonality, so it won’t sound ‘filtery’, it’ll sound like it was meant to be that way.

Airwindows Baxandall uses my interleaved biquad filters (original, purest form, not meant for rapid automation) that run inside a Console5 instance to deepen the sound of the filter.
