The EQ that sees
your whole mix.
Every other EQ shows you one track in solo. DeltaEQ’s bands see the context — the other tracks, the sidechain, the masking — and move only when the mix actually demands it. Surgical when you ask, automatic when you let it.
You EQ in solo. You listen in a mix.
That vocal cut sounded perfect in solo. Then the guitars came back and the problem was never the vocal — it was the overlap.
DeltaEQ draws the other tracks behind yours, flags the bands where you’re being buried, and gives you bands that react to the mix itself. Stop guessing which track owns the frequency. Look.
An EQ move that happens only when it has to.
Put CTX on a band and it ducks only while another track — or the sidechain — actually needs that space. Kick hits, bass dips. Vocal enters, pad opens. Nothing plays, nothing moves.
With the @SC key the detection runs sample-accurately on the sidechain — the duck lands on the transient itself, not a spectral average later. Surgical & instant on the sidechain, contextual & smooth across tracks.
Duck the frequencies, not the track.
The SPECTRAL band listens to the sidechain, finds its spike frequencies, and places a swarm of narrow bells exactly there — ducking precisely what masks, leaving everything else untouched.
The key curtain hangs the detected spectrum from the top of the plot — cause above, effect below, each curtain spike directly over the bell it triggers. Sidechain ducking you can read.
Every band is a specialist.
Channel-aware from the start: every band targets Stereo, L, R, Mid or Side — colour-coded the same way across the whole Delta family.
One handle. The whole overtone series.
A resonance never rings alone — its overtones ring with it. The Harmonic band rakes a series of bells across the harmonic ladder and moves them with one handle.
Pair it with Pitch-Track and the whole rake follows the note — a moving-target notch that stays in tune with the performance. Hover any band and the Harmonic Lens reads the note, the cents, and the live overtone ladder.
The Delta family finds each other.
Drop Delta plugins anywhere in your project and they connect — no bussing, no routing. DeltaEQ’s context comes from the other instances; DeltaMeter’s SWARM wall shows every DeltaEQ curve in the project.
And it’s not just display: grab a band from the wall and EQ any track without opening its window. Your whole mix, one view, every curve at your fingertips.
Small tools, big payoff.
Context is the feature.
Every DeltaEQ license includes DeltaWall.
A free standalone app that shows every Delta plugin in your project on one wall — one live tile each, no routing or setup — so you can watch the whole session from one window.
Almost there.
DeltaEQ is in final development and in daily use on real mixes. The open beta — with the same buy-once, every-update-free deal as DeltaMeter — is coming soon.
