SUS4 Dynamic EQ

Frequency-selective compression with EQ-style controls. No separate sidechain routing.

Included in the SUS4 plugin bundle. One licence, every plugin, every update.

Frequency-selective compression with EQ-style controls and no separate sidechain routing. Tame a resonant note, a harsh cymbal or a boomy room only when it crosses the line, then let go.

Bell, shelf and cut bands that each react to level: surgical when you need it, invisible when you don’t.
