Wider sound.
Same bass.
A real-time spatial engine that opens up whatever you're already listening to — without touching the loudness, the compression, or the low end. Bass-safe by design, where most "3D audio" tricks go muddy. Browser today, phone apps next, and the same engine under the hood of the full Master Trust Engine mastering console.
▶ TRY IT — NO DOWNLOADBass stays exactly where it was
Most phone "surround" effects widen the whole signal, bass included — which is exactly why they turn hollow or thin on a phone speaker or in mono. Surreal Audio splits below 150 Hz and only widens above it, the same move mastering engineers pay for in professional tools, not something built into stock phone effects.
Nothing gets louder or more compressed
This only ever changes the space, never the volume. It doesn't fight the mix the original engineer already balanced.
Proof, not a black box
The same phase-correlation meter from the Master Trust Engine console is right there on the demo — watch the bass stay locked near +1 while the top end opens up, instead of just trusting a toggle.

Surreal Audio is the consumer side of the same DSP engine that powers The Master Trust Engine — the institutional mastering and rights-settlement infrastructure behind it. Different product, different audience, same engine underneath.
