Baby Audio Smooth Operator Pro: A New Master of Resonance Control for the Perfect Sound
One-Click Solution for Resonance Problems
Baby Audio Smooth Operator Pro is a new and greatly expanded version of the software manufacturer’s well-known spectral processor. The plugin is based on its successful predecessor Smooth Operator from 2021, but has been extensively developed over the last four years, adding numerous new features. The Pro Edition is aimed at audio professionals who need absolute control over the sound of their tracks during mixdown. Smooth Operator Pro promises to effortlessly reduce unwanted resonance in the frequency spectrum and significantly improve clarity and balance in complex mixes.
Baby Audio Smooth Operator Pro: A New Approach to Precise Frequency Control in Your Mix
The Baby Audio Smooth Operator Pro spectral processor is based on an advanced core algorithm specifically designed to efficiently identify and precisely adjust overemphasized frequency ranges. It works much like a dynamic equalizer or multi-band compressor, eliminating unwanted resonance. The plugin is particularly effective in problematic areas of the lower midrange and sharp frequency peaks. The new stereo imaging functions also allow you to control the width of the stereo image, resulting in a much more lifelike sound.
One of the most significant innovations in Baby Audio Smooth Operator Pro is Resonance Suppression 2.0. Unlike conventional plugins, which often use global settings, this technology allows you to adjust individual frequency ranges. You can create individual profiles for each frequency point and adjust them dynamically. This allows you to combine multiple spectral processors, each optimized for different problems, in a single instance. Very cool! This gives you tremendous flexibility to fine-tune your sound without time-consuming detours.

Mixing Clarity at the Touch of a Button and Without Compromise
Despite the advanced options, the user interface remains uncluttered and intuitive. Targeted options are at your fingertips when you need them, but never interfere with your workflow when you do not. More than 100 presets from professional mixing and mastering engineers also help you get started quickly and deliver results you can use right away. Baby Audio Smooth Operator Pro is based on a sophisticated mix of automated optimization and manually controllable details.
The Baby Audio Smooth Operator Pro plugin can also be used for mastering and sound design. Whether it is vocals, drums or complex instrumental mixes, Baby Audio Smooth Operator Pro offers flexible options to improve the sound and allows you to react immediately and specifically to sonic problems. In my opinion, this tool is a must-have for any plugin collection.
