EQ & Dynamics

Shape the tone, then tighten it.

A five-band parametric EQ next to a compressor, so you can fix the balance and control the level in one place.

Five-band parametric EQ from 80 Hz to 12 kHz
Band energy analyzer showing where the energy sits
Compressor with four character styles, from Transparent to NY Parallel
Rumble filter, parallel compression and dithering for 16-bit exports

Dynamics

Control each part of the spectrum.

Split the sound into low, mid and high and compress each band on its own, then check the stereo picture.
