STEREOVAULT

The deal

$80 at Plugin Boutique (down from $160). No coupon needed. Deal ends June 3.

What it is

STEREOVAULT is a stereo width and imaging processor from Mastering The Mix. It uses M/S processing across up to 6 independent frequency bands, so you can widen the high end without touching the low. Every adjustment is level-matched automatically, meaning you hear the actual stereo change - not a volume bump disguising itself as width.

Who it's for

Mixing and mastering engineers who want precise, frequency-specific stereo control. It fits producers working on dense mixes where blanket widening causes phase problems, and anyone who reaches for third-party stereo tools on buses, drums, synths, or full masters.

Key features

• Six processing tabs cover spread, creative widening, panorama, width, rotation, and mono cleanup - each with different techniques for different use cases
• A reference track import lets you match the stereo profile of any song you load
• Transparent Mode uses clean crossover filters for mastering work, while Flexible Mode adds creative options like Haas delay and chorus-based widening
• The real-time visualizer shows your stereo field in both 2D and 3D views with phase warning indicators so you can spot problems before they hit the mix bus
