Mastering The Mix STEREOVAULT is the most complete and most intelligent stereo imaging plugin available for Mac — a single environment that analyzes your audio, helps you find the right stereo width for your material, then gives you 10 powerful processing modes across 7 tabs to shape width, depth, focus, and mono-safe space, with every single move automatically level matched so you always hear the effect of your processing rather than just a louder signal tricking your ears. From transparent Mid/Side widening and surgical side EQ to creative spatial effects like Haas, Flux, Chorus, and Space — and with Smart Presets that analyze your audio and suggest the most relevant starting point — STEREOVAULT replaces a full chain of stereo tools with one beautifully designed, deeply capable macOS plugin trusted by mixing and mastering engineers worldwide.

10 Processing Modes — All 7 Tabs Explained
Tab 01
📊 Spread
Pristine
Diffuse
Vintage
The cleanest way to widen your stereo image. Pristine uses Mid/Side processing for direct control. Diffuse applies Gerzon per-band diffusion for ultra-transparent widening. Vintage uses classic frequency-splitting for adding life to flat or mono-heavy sources.
Tab 02
✨ Creative
Stretch
Flux
Chorus
Haas
Space
Bold, characterful width using spatial effects. Stretch creates shimmery width through comb filtering. Flux produces a slow evolving drift for pads. Chorus adds rich modulated movement. Haas gives vivid sense of direction. Space wraps sounds in tight diffused reverb for physical depth.
Tab 03
🔄 Panorama
Pan
Skew
Pan and reposition audio across the stereo field on a per-band basis. Pan for standard left/right balance. Skew to swap channel energy — ideal for correcting stereo imbalances without pulling the whole image off-centre.
Tab 04
↔️ Width
Blend
Balance
Redistribute Mid and Side energy to push centre content outward or bring the sides back in. Blend swaps mid and side signal. Balance lets you turn down either channel independently — perfect for tightening wide low-end or opening up highs.
Tab 05
🔃 Rotate
Stereo
Mid
Side
Repositions the stereo image by rotating the signal rather than adjusting level. Small amounts subtly tilt the image. Apply to the full Stereo signal or target Mid and Side independently for precise spatial control on Mac.
Tab 06
🔬 Clean
Side EQ
Mid EQ
A transparent Mid or Side EQ for surgical width shaping. Side boosts or cuts the side signal in dB with zero coloration. Mid adjusts centre-channel energy directly — the cleanest way to fix problem frequencies in your stereo field on Mac.
Key Features
🧠
Smart Analyze Presets
Hit Analyze — STEREOVAULT listens and suggests Focused, Balanced, Wide, or Super Wide presets calibrated to your actual audio on Mac.
⚖️
Automatic Level Matching
Every adjustment is automatically level matched — you always hear the processing, not a louder signal tricking your ears on macOS.
🎛️
Transparent + Flexible Mode
Transparent Mode shares one band layout across all tabs for phase-stable mastering. Flexible Mode gives each tab its own independent layout for mixing freedom.
📡
Scope — Phase Monitor
Real-time stereo correlation monitoring — catch phase cancellation instantly before it causes problems in your mix on Mac.
🎚️
Trim — Input/Output Gain
Handle input and output gain in L/R or M/S domain from a handy toolbar pop-up — no cluttering the main interface.
🔀
I/O Routing Control
Control signal routing for input and output — including mono, swap, and side extraction — directly from the toolbar on macOS.

Frequently Asked Questions
What is Mastering The Mix STEREOVAULT for macOS? ▾
STEREOVAULT is a stereo imaging plugin for macOS from Mastering The Mix — available as AU, VST3, and AAX with native Apple Silicon support for macOS 10.15 and later. It analyzes your audio and suggests the ideal stereo width preset, then gives you 10 processing modes across 7 tabs covering transparent Spread (Pristine/Diffuse/Vintage), creative spatial effects (Stretch/Flux/Chorus/Haas/Space), per-band Panorama (Pan/Skew), Width redistribution (Blend/Balance), Rotate (Stereo/Mid/Side), and surgical Clean Mid/Side EQ. Every adjustment is automatically level matched so you always hear the processing rather than volume differences. Priced at £59 with a 30-day money back guarantee and 2 license seats standard.
What is the difference between Transparent and Flexible mode? ▾
Transparent Mode in STEREOVAULT shares one band layout across all processing tabs — meaning every tab uses the same frequency band positions. This creates the most phase-stable, cohesive processing ideal for mastering on Mac where phase integrity is critical. Flexible Mode gives each tab its own independent band layout, so you can set different frequency ranges per processing mode — giving you more creative freedom for mixing and sound design. Choose Transparent for mastering and mix bus, Flexible for individual channel processing and more experimental workflows on macOS.
Does STEREOVAULT work with Logic Pro on Mac? ▾
Yes — STEREOVAULT works natively with Logic Pro on Mac as an Audio Unit (AU) plugin with full Apple Silicon native support, meaning no Rosetta 2 translation is required on M1, M2, M3, or M4 Macs. It is also compatible with all other macOS DAWs that support AU, VST3, or AAX — including Ableton Live, Pro Tools, Cubase, Studio One, Reaper, and Luna. macOS 10.15 Catalina or later is required.
