Spectral signal balancer for mixing and mastering, removing mud, harsh resonances, and masking. Features Resonance Suppression 2.0, flexible node control, dual correction modes, imaging controls, and 184 presets.
Purpose
Smooth Operator Pro is a spectral signal balancer from BABY Audio designed to clean up frequency build-up in audio. It targets mud, harsh resonances, and masking, which can obscure clarity in a mix. The plugin works in real-time, rebalancing audio based on a user-defined target curve.
This approach helps individual tracks sit better in a mix, and can also be applied to an entire mix bus to reshape tonal balance. The interface is intended to be intuitive, allowing quick setup of a global threshold and target curve for automated correction.
Key Capabilities
The plugin includes Resonance Suppression 2.0, an upgraded engine that dynamically controls resonant frequencies. Users can set individual dynamic profiles across the frequency spectrum, which is useful for addressing specific issues like harsh cymbals or muddy bass. This precision allows for targeted fixes without affecting the rest of the audio.
Two correction algorithms are available: Even for transparent correction and Skew for a more characterful, musical tone. The plugin also provides flexible node control, letting users add or remove control points anywhere on the curve. Imaging and stereo width controls are built in, and dynamic response can be adjusted to react to transients and movement.
Workflow
Smooth Operator Pro is designed to speed up the mixing process. Users can start with one of 184 presets crafted by engineers like Grammy nominee Craig Bauer and producers Max Jaeger and Preston Reid. These presets provide a starting point for vocals, synths, drums, or full mixes, and can be tweaked to taste.
The real-time visual feedback shows spectral dynamics in an animated interface, making it easier to understand what the plugin is doing. Automation and MIDI control are supported, which can be used to adjust parameters over time. The plugin is compatible with all major DAWs, though it requires the free KONTAKT PLAYER version 7.8.1 or higher.
Applications
This tool is suitable for mixing vocals, taming synth harshness, tightening drums, and mastering. For vocals, it can remove resonant peaks that cause sibilance or harshness. On synths, it can reduce mud in the low-mids while preserving brightness. For drums, it helps control transient build-up and ringing.
When used on a master bus, it can provide overall tonal balance and reduce masking between instruments. The dual correction modes offer flexibility: Even for transparent fixes, Skew for adding musical coloration. The imaging controls allow shaping stereo width, which is useful for creating space in a mix without changing the core tone.
