Flat, lifeless source holding your mix back?
It’s a common struggle: tracks that lack a sense of drama and emotional lift. You try EQ, compression, saturation – but the feel still doesn’t translate.

Enter the StressBox – a dynamics tool that shapes musical tension.

Turn right for aggressive compression that pulls the room sound forward and slams you with urgency and in-your-face energy.

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

• Control the tension and feel of any musical source
• Inject life and drama into your tracks
• One continuous knob: compression to the right, expansion to the left
• Add punch, urgency, and size with compression
• Craft intimacy and tightness through expansion
• A deeply musical tool – no technical skills required
