01Overview

Magma StressBox is a dynamics processor from Waves that uses a single continuous knob to move between compression and expansion. Compression sits on the right side of the control, adding punch, urgency and size. Expansion sits on the left, adding intimacy and tightness. The developer describes it as a musical tool that needs no technical skills, and it can be placed on any musical source in a mix.

03In depth

One Knob for Compression and Expansion

StressBox combines two dynamics behaviors in one control. Turn the knob right and the processor applies compression, which Waves describes as pulling the room sound forward and adding urgency and energy to a sound.

Turn the knob left and the processor applies expansion, which Waves says enhances transients and shortens reverb tails for a tighter, more controlled feel. Because the control is continuous, you can move gradually between the two rather than switching modes.

Automating Energy Between Song Sections

The developer notes that the knob can be automated. Riding the setting over time lets you build lift, movement and contrast between sections such as verses and choruses.

This makes StressBox useful for changing the emotional shape of a track across its arrangement, not only for processing a single static sound.
