Delta Metering · VST3 · AU · CLAP · Standalone
Hear What Your
Effects Are Doing.
DeltaMeter extracts and visualizes the exact difference signal of your audio chain. See and hear what every compressor, limiter, or EQ is really doing.

The Concept
What is a Delta Signal?
Every effect changes your signal. DeltaMeter subtracts output from input — inverted and summed — to reveal exactly what changed. The difference, made visible and audible.
INPUT
Dry signal before the effect chain
→
EFFECT
Compressor, limiter, EQ, saturation…
→
DELTA ∆
The exact difference. Visible & audible.
Δ = Output − Input · inverted · summed
Signature
The Things Nobody Else Shows You
Three views that turn invisible processing into something you can read in a second.
TACO™
Footprint
Time-Averaged Chain Observation
A time-averaged transfer curve of your whole chain, wrapped in a variance ribbon. Thin band? Static EQ. Wide band? Dynamic processing. Your chain's fingerprint, at a glance.
SWARM™
God-View
Synchronized Wall of All Running Meters
Every DeltaMeter in your project — live, in one window. Drum bus, vocal, master, side by side. No bussing, no routing: drop instances anywhere and they find each other.
SWM™ · MCP™
Width
Spectral Width Mapping · Mono-Collapse Prediction
The stereo field, per frequency — and how your chain changed it. A mono-risk strip flags the exact bands that collapse when summed to mono, before your master does it for you.

The Toolkit
See it. Hear it.
Pick a source to monitor and the analyzer follows it automatically. One mental model, no hidden modes.

Use Cases
See What You Couldn't Hear
Compressors
Hear exactly how much signal is being attenuated — and when. Understand attack, release, and coloration.
Limiters
Is your limiter transparent or colored? The delta signal reveals the difference immediately.
EQ & Filters
See every frequency boosted, cut, or shaped. Correlate what you hear with what you see.
M/S Processing
Analyze Mid and Side channels independently. Spot unwanted correlation or excessive widening.
L/R Channels
Compare left and right independently. Detect phase issues or level imbalances instantly.
Saturation
Visualize harmonic content added by tape, tube, or overdrive — the exact coloration in spectrum form.
