Blindfold EQ by AudioThing
Blindfold EQ is a freeware EQ plugin inspired by a quote by Matt Wallace from the book Recording Unhinged by Sylvia Massy. It has 4 bands (LowShelf, LowMid, HighMid, HighShelf), but each knob is blind.
There are no indicators or numbers to show frequency values, gain values or Q values. You’d have to use your ears.
