smart:comp 3 is an intelligent compressor plug-in from Sonible that uses AI analysis to map musically viable compression settings, offering transparent results and efficient multi-track workflows.

Purpose and Core Concept
smart:comp 3 is designed to support creative intent by translating audio signals into an intuitive map of viable compression characteristics. Instead of presenting abstract numbers, the plug-in uses AI-powered analysis and automatic parametrization to highlight how far a track can be dynamically shaped. This semantic approach reduces trial and error, helping you achieve transparent, musical results faster.
The central Compression Matrix displays the full spectrum of musically relevant compression settings based on your material. By visualizing the potential for dynamic shaping, smart:comp 3 lets you explore your track’s possibilities without guessing. This makes it especially useful for engineers who want a clearer path from initial idea to polished sound.
Key Capabilities
smart:comp 3 provides all common compression controls—threshold, ratio, attack, release, and mix—alongside advanced features for granular shaping. Three Style options (Clean, Smooth, Aggressive) offer well-calibrated compression engines for different contexts, while a Custom style gives full control over attack/release shapes and saturation behavior. This flexibility suits both quick adjustments and detailed sound design.
Unique technologies include Spectral Compression and Spectral Ducking, which apply processing only where needed to preserve natural dynamics and energy. Additional features like Input Riding, Mid-Side Mode, and a zero-latency Minimum Phase Mode extend its utility. These tools allow precise, context-aware dynamics management without compromising the original character of the audio.
Workflow and Multi-Track Control
A standout feature is Group Mode, which enables joint control of up to seven tracks simultaneously via inter-plugin communication. This accelerates complex mix workflows, such as tightening drum channels or aligning compression across multiple vocal takes. All grouped instances appear in the Compression Matrix and signal history, allowing batch edits of threshold, ratio, attack, release, and mix from a single window.
This approach reduces the need to jump between instances, improving cohesion and consistency across a session. Whether you’re balancing a full drum set or harmonizing background vocals, group control simplifies the process. The result is a more efficient workflow for large projects, saving time while maintaining a unified sonic balance.
Practical Applications
smart:comp 3 suits a range of scenarios, from single-track dynamics control to multi-channel group processing. Its intelligent mapping helps you quickly find appropriate compression settings for vocals, drums, or full mixes. For rhythmic material, Spectral Ducking can attenuate specific frequencies only when needed, preserving transients and groove.
Mid-Side Mode allows independent compression of mid and side components, useful for stereo width control. The zero-latency option is beneficial in live or real-time monitoring situations. By combining AI-driven suggestions with detailed manual controls, smart:comp 3 adapts to both creative experimentation and technical precision, making it a versatile tool in any mixing environment.
