The idea is to use a basic equal loudness curve (in this case based on "Grey Noise") to compensate for volume changes, to explore what that sounds like. The attached Combinator keeps a consistent peak level within a dB or so as the volume is lowered, while also increasingly adjusting the overall EQ curve to compensate for the volume change.
At the top position, there is no difference/no EQ applied. If you play white noise through it, it will be flat in both settings at this point. But as you lower the fader, you hear more of a difference when bypassing the EQ curve.
Interestingly, it's not that obvious when fading out with the EQ curve engaged, it's only when you bypass when the fader is at the half way position or so that you can really tell what's going on.
I will likely explore this device and the concepts behind it on the next live stream, may even try to build a mix using these faders instead of 'normal' faders just to see what happens.
