DMASK Beta

Make space. Change nothing else.

A linked, cross-channel un-masker. Drop it on the track you want to protect and the one that's burying it. It clears the frequency overlap where they clash, only there, and proves, band by band, that it touched nothing else.

Clean a track against itself.

The idea

One sound is burying another. Un-bury it.

That's masking: the synth eats the vocal, the bass swallows the kick. D·MASK carves a pocket for one track inside another. It moves only where they clash.

The carve is perceptual, across 24 ERB critical bands, the spacing your ears actually use. And it's algebraic: when a band isn't being carved, the output equals the input, to the bit.

How far it goes stays yours. Max GR puts a hard ceiling in dB on any single band, so nothing gets gouged when the arrangement thins out, and Speed sets how quickly the carve lets go: tighter on busy material, slower for a smoother trail.

Why it earns the insert slot
01 · Honest

It proves it.

When a band isn't being carved, the output equals the input, bit-exact. A loudness-matched blind A/B lets anyone judge the change, and a Listen mode solos exactly what was removed. Set up two versions of a carve, flip between them instantly, and they save with the project. No faith required.

02 · Perceptual

It knows when to stop.

The carve works across 24 ERB critical bands, the spacing the ear actually uses. Perceptual mode then builds the real masked threshold from the masker and cuts only as deep as it takes to lift the source above it, not a dB more. A band that already clears the threshold is left completely untouched, and a smooth pad no longer gets carved like a distorted guitar. In our STOI testing across real multitrack sessions: +63% more intelligibility for the same collateral damage.

03 · Session-wide

It sees the whole mix.

A Matrix view lines up every D·MASK in the session in one window, each protected source and the maskers ducking for it. The one view a per-track plug-in can't show.

The Matrix

Air-traffic control for your mix.

Flip to Matrix and the whole session lines up: every protected source and the maskers burying it, with the exact bands where they clash.

Set which source wins a clash, drive each masker's depth, or solo any masker's residual, all from one window, without opening that track.
