The compressor that
shows its work.

Every compressor asks you to imagine what it’s doing. DeltaComp draws it — the exact gain reduction on your material, over time, as you turn the knobs. Set attack by seeing the transient survive. Transparent, honest, everyday.

The problem

“Fast attack” means nothing.

Dry vs wet over time — the gain reduction is the gap between them

One unit’s “fast” is another’s “slow.” The numbers on the box tell you what the detector was asked to do — not what happened to your audio.

DeltaComp scrolls the dry signal, the wet signal, and the exact gain reduction between them. When the transient survives the attack, you see it survive. When the release pumps, you see the pump — and you fix it in one move instead of five listens.

Channel-aware

Stereo, L/R, or Mid/Side.

DeltaComp compresses in the domain your material lives in: classic Stereo, independent L / R lanes, or Mid / Side — each lane with its own threshold, ratio, knee and timing.

Glue the centre while the sides keep breathing. Tame the hi-hat that only lives on the left. Every lane is drawn in its own colour — the same channel language as the whole Delta family.

StereoClassic linked compression — one lane, the whole image.
L / RIndependent lanes per speaker — tame a one-sided hi-hat without touching the other half.
M / SCompress the centre and the sides separately — glue the middle, leave the width breathing.

Honest by design

Louder is not better.

Every compressor demo sounds “better” because it’s louder. AUTO makeup level-matches wet to dry, so bypassing compares the compression — not the volume jump.

And the crest readout shows dry → wet in numbers: exactly how much punch you traded for density. When the trade is worth it, you’ll see that too.

Sidechain

Duck to anything.

Feed any track into the sidechain and DeltaComp ducks to it — with a permanent LC / HC detector filter so rumble and hiss never drive the decisions.

The scope draws the key signal too, so you see what the detector heard and what it did about it — kick in, bass down, and both of them on screen.

Better together

Part of the Delta family.

Delta plugins find each other in your project — no bussing, no routing. DeltaMeter’s SWARM wall picks up every DeltaComp and shows its gain-reduction story per track, live.

Your compressors, your EQs and your analyzers stop being separate windows and become one view of the mix.

And the rest

Small tools, big payoff.

Auto makeup
Level-matched wet vs dry — bypass compares loudness-fair, so louder never fools you.
Auto release
Program-dependent release that lengthens as GR deepens — loud passages don’t pump, quiet tails recover naturally.
Peak · RMS
Two detector characters — grab transients or ride the body.
Sidechain duck
Feed an external key and duck to it, with a permanent LC/HC detector filter to keep rumble out of the decisions.
MIX
Parallel compression on the dial — crush the copy, blend to taste.
Crest dry → wet
Read exactly how much punch the compression traded away — as a number, not a feeling.
Loudness rail
Dry and wet levels side by side, with a dB readout under your cursor.
Presets
The house preset browser — save, step, share as plain files.
60 fps · GPU-drawn
The scope renders on the GPU — buttery at any window size.
Included free

Every DeltaComp 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.

Status

Almost there.

DeltaComp is in final development and compressing real mixes daily. The open beta — with the same buy-once, every-update-free deal as DeltaMeter — is coming soon.

DeltaComp — Open Beta
Coming soon
Beta pricing and date will be announced on the news page. Meanwhile, DeltaMeter — the analyzer the whole family is built on — is in open beta today.
