Waves Magma StressBox

Flat, lifeless source holding your mix back?

Turn left for expansion that enhances transients, shortens reverb tails, and wraps your track in a tighter, controlled feel.

Dial in Emotion

A single knob shapes your track’s emotion – from intimate expansion to explosive compression. Each turn uncovers new character, on any source you place it on.

Automate the Feel

Ride energy and emotion with automation – create lift, movement, and contrast between verses and choruses.
