CortVerb Advanced reverb engine.

A VST3 reverb effect built on a Hybrid feedback-delay-network engine, wrapped in a hardware-styled interface: a central digital screen with six live-visualization pages, brushed-aluminum panels carrying 12 precision knobs, and speaker-cloth side panels with chevron edge lights. Built for mixing, sound design, and production.

What it does

Precision reverb, tactile control.

🎧

12 tactile knobs

Two brushed-aluminum panels: pre-delay, size, decay, width, diffusion and mod rate on the left; low cut, high cut, damping, early level, late level and output on the right. Every dimension of the tail under your fingers.

📊

Live visualization

The central screen redraws in real time — decay envelopes, reflection taps, the EQ response curve and the modulation LFO all animate as you turn the knobs, with a large live reverb-time readout.

🎛️

Hybrid FDN engine

A feedback delay network drives the late field, fed by configurable early reflections. Diffusion, size and damping shape everything from tight rooms to endless ambient washes.

🔌

Auto-duck sidechain

An internal ducker pulls the wet signal down under loud transients and lets it swell back as they pass — so vocals and drums stay clear without drowning in reverb.

⚙

Six screen pages

Main, Early, Late, EQ, Mod and Advanced. Each page focuses one part of the engine with its own graph and readouts, so depth never clutters the panel.

🎵

Eight factory presets

From Big Hall and Cathedral to Drum Room, Plate and Spring Tank — browse with the on-screen arrows or the dropdown, then tweak from there.

On screen

Six views, one engine.

Every screenshot below is the real plugin. Each tab renders its own live graphic so you can see — not just hear — what the reverb is doing.

Main

Decay envelope

The full reverb tail plotted in dB over time, with algorithm, quality, damping and cut readouts.

Early

Early reflections

Discrete reflection taps spread by size and diffusion — the initial spatial print of the room.

Late

Late tail

Full-band decay against the damped-highs curve, so you can dial warmth into the sustain.

Frequency response

The combined low-cut / high-cut / damping curve across 20 Hz–20 kHz, drawn live.

Mod

Modulation

An animated sine LFO with rate and depth — subtle motion that stops the tail ringing metallic.

Advanced

Auto-duck & engine

Sidechain ducking amount plus engine details — Hybrid FDN, high quality, sub-millisecond latency.

Under the hood

Built like hardware.

CortVerb's interface is modeled after premium rack gear: a machined chassis with chamfered bevels and powder-coated steel grain, brushed-aluminum control panels held by visible screws, and woven speaker-cloth side panels lit by blue chevron edge lights.

At the centre is a fully rendered digital display — interactive graphs, six tabbed pages, a factory-preset browser and readouts that respond to every parameter change in real time.

Stereo-in / stereo-out effect processor
Hybrid feedback-delay-network reverb architecture
Configurable early reflections and late field

Sine modulation with adjustable rate and depth
Auto-duck sidechain driven by input transients
Width control for mono-to-stereo spread
Pre-delay up to 200 ms for spatial separation

Every detail

12 knobs. Full control.

Pre-Delay

0 – 200 ms. Separates the dry signal from the reverb onset for clarity and depth.

Size

Scales the perceived space, from tight closets to vast cathedrals.

Decay

0.1 – 10 s. Sets how long the tail sustains before fading to silence.

Width

Stereo spread from mono to fully wide. Shape the spatial image of the reverb.

Diffusion

Density of reflections. Low for discrete echoes, high for smooth, washed tails.

Mod Rate

Speed of the internal LFO. Adds subtle motion to prevent metallic resonances.

Low Cut

20 Hz – 1 kHz high-pass on the wet signal. Keeps the low end clean and controlled.

High Cut

1 – 20 kHz low-pass to darken the tail. Simulates air absorption and natural rolloff.

Damping

Frequency-dependent decay. Higher damping absorbs highs faster for warmth.

Early Level

Volume of the early reflections. Shapes the initial spatial impression.

Late Level

Volume of the diffuse tail. Balance against early reflections for character.

Output

Master output level. Compensate for gain changes across different settings.

Plus on-screen controls: Mix, Early/Late balance, Shelf, Mod Depth, Transient and Auto-Duck.
