Not rated yet

A reverb plugin that analyzes a recording, extracts its room acoustics and reapplies them to dry audio, built for ADR, Foley and dialogue matching.

A neural network trained on over 30,000 rooms builds the reverb profile in seconds; the technology won a 2026 Engineering, Science & Technology Emmy.

Best for: Vocals, Sound Design. Genres: Ambient & Cinematic.

Keywords: post-production, room, AI/machine learning, dialogue, sound design, spacious, visual feedback, built-in analyzer, CPU-light, impulse-response based, spectral, subtle, vocals.

What it does

Chameleon lets you "imitate any reverb": it analyzes production recordings, extracts their natural acoustics and recreates them as a realistic reverb for studio material. Accentize aims it at reverb matching, ADR, Foley and immersive sound design.

Machine learning: trained on over 30,000 room examples to capture the temporal and spectral character of a space.
Profiles: generate reverb profiles in seconds, store them in a library window, and export impulse responses as WAV files.
Visualization: reverb shown as a 2D or 3D spectrogram.
Surround version: Chameleon Surround builds a 3D room model from a mono signal and outputs up to 9.1.6, with 80 presets and surround visualization modes.
Presets: the standard mono/stereo version includes 27 basic presets.

It supports 44.1 to 192 kHz and has a 7-day trial (version 2.1.5 at the time of writing).

When to use it

Chameleon is the pick when the target is a specific production recording. Where Audio Ease Altiverb 8 matches spaces with a library of sampled real rooms, and Valhalla Room or FabFilter Pro-R 2 make algorithmic spaces you tune by ear, Chameleon listens to the take and builds a matching reverb for ADR and Foley.

Best for: matching ADR and Foley to production dialogue, extending cut-off reverb tails, and placing dry recordings in a captured space.
Genres: film, TV, games and other post-production; music use is secondary.
Look elsewhere if: you want a lush, adjustable music reverb; reviewers found the reverb itself fairly basic.
Standout: extracting a reverb profile from ordinary dialogue in seconds instead of hunting for a matching IR.

What producers say

Post-production reviewers praise how natural and fast the matching is, with some wanting more control.

Production Expert (2024) Paul Maunder called Chameleon Surround "another standout plug-in from Accentize" and "surprisingly CPU efficient."
344 Audio found the results "subtle but brilliant" and called it "a powerful plug-in at a very reasonable price."
Gripe: 344 Audio said "the sound of the reverb itself is quite basic" and wanted more manipulation options.
