Cool, thanks! Yeah I didn’t know if there was some psychoacoustic idea behind it. It’s an interesting idea for sure.
With the mixes I get I’m usually doing the opposite- not a lot of macrodynamics in a lot of diy indie + punk music, so often I’m making small momentary gain boosts to help accentuate a chorus or cool part. Usually to either help along the song or counteract some of my compressors’ macrodynamic leveling.
