RTM Audio D Mask 1.9.84 solves a common mixing problem: two sounds fighting for the same space, like a vocal buried by a guitar or a kick drum hidden under a bass line. Place one instance on the track you want to protect and another on the track covering it, and D Mask carves a small pocket exactly where the two overlap. Its analysis works in 24 perceptual bands spaced the way hearing works, so it opens space where you notice the clash. A Self mode tames harsh edges on a single track. Updated Aug 21, 2026.

FAQs

How is this different from a normal equalizer?

A normal EQ is static. D Mask listens to two tracks and only carves where they clash.

Can it work on one track only?

Yes. Self mode needs no partner instance and helps with harsh edges and boxy build up.

Is it a subscription?

No. RTM Audio sells one time licenses, and a free trial lets you test the full plugin first.
