Libra is a pink shelf EQ. A what you say? Essentially tune the notch via frequency to your fundamental, and then apply a width, and a tone slope. It was an experiment in obtaining an easier pink spectrum distribution of harmonics. More an instrument EQ, and not a master EQ. In short: A simple filter for removing peaks, and rebalancing bass to treble.
