Curves Equator is a smarter resonance suppression plugin. It immediately improves any full mix, vocal, instrument or sample by removing problematic frequencies, fixing resonances and balancing inconsistencies.
Additionally, it can learn your content & safeguard your work with a personalized suppression curve to avoid overprocessing. It offers groundbreaking frequency unmasking by learning the sidechain of a clashing source and dynamically applying the inverse curve on the part you’re mixing.
Equator is the first in our new Curves Spectral Series of plugins, which pioneers the evolution of EQ. Two more Curves plugins will be available in early 2025: Welcome to your first self-driving EQs!

I tried this EQ on a few guitars and found it really useful. They may be on to something.
