At its core, Smooth Operator Pro still uses advanced spectral processing to automatically target and tame bloated frequency energy across the spectrum. Users can use the plugin to achieve clarity in their mixes and address common issues such as boomy low-mid buildup, harsh resonances, and masking.
One key upgrade from the original is the ability to make precise frequency-specific adjustments. While the previous version only allowed you to apply global settings to affect the signal, the Pro version lets you freely place and remove nodes across the frequency spectrum and create individual dynamic processing profiles for each node.
Want to tame a splashy cymbal in just the left channel? Smooth out a bass thump only on the side channels? Apply a softer compression to a vocal peak at 2.5kHz? You can do all of that and more in the same plugin.
Smooth Operator Pro also features two new correction algorithms, Even and Skew, as well as improved stereo imaging tools for you to take full control of the harmonic content in your mix.
Like its predecessor, Smooth Operator Pro offers a fast workflow with the surgical features being optional. It includes 184 presets by engineers from around the world to add mix clarity right out of the box.
The plugin is now available at an introductory price of $79 (U.P. $129). Users who own the original version can upgrade for $29.
