sonible smart:comp 3 review
A focused AI compressor for automatic dynamics control, spectral shaping, and ducking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
sonible smart:comp 3 is a compressor plug-in for mixing, production, recording, and live workflows. It analyzes incoming audio and presents compression behaviors through a Compression Matrix, while automatic parameterization helps establish compression settings. The plug-in is designed for producers, engineers, and performers who want AI-assisted level control inside a digital audio workstation or other supported host. It runs on Windows and macOS and supports VST, VST3, AU, and AAX formats.
Its standout feature set centers on dynamics control with spectral awareness. Spectral Compression and Spectral Ducking allow compression behavior to respond to frequency content, while Input Riding helps stabilize level variations before or alongside compression. Compression Scope provides visual feedback, and users can choose Clean, Smooth, Aggressive, or Custom styles. The plug-in also includes zero-latency minimum-phase and linear-phase modes, Mid-Side processing, and a Group Mode that links and controls up to seven instances. These features give smart:comp 3 a broader control surface than a basic automatic compressor while keeping its purpose specific.
The published offer is a paid plan named smart:comp 3, with a 30-day free trial and no free plan. Its listed plan highlights include Compression Matrix, Group Mode, Spectral Compression, and Spectral Ducking. Choose it if automatic compression, spectral dynamics, and linked control across multiple instances are central to your workflow. Choose another option if you need a full mixing system rather than a dedicated compressor plug-in, or if your host environment falls outside Windows and macOS support.
