Smooth Operator Pro Upgrade: Dynamic Spectral Balancer by Baby Audio Free Download

The plugin is built around a target curve. You set the desired tonal balance, then turn the global threshold knob until the plugin begins balancing the audio. Deeper settings are available for users who want more control.

Where many spectral balancers apply one global setting to the whole signal, Smooth Operator Pro lets you override the settings for any frequency node. You can set individual dynamic profiles across the spectrum, for example targeting the sides at 150 Hz to clean up bass, taming a harsh cymbal at 7.5 kHz, or applying a softer compression profile to a vocal at 2.5 kHz.

Baby Audio says two correction algorithms, Even and Skew, are included.

Sidechain mode uses the spectral content of another track to rebalance the current signal. Baby Audio gives the example of routing a lead vocal into a guitar track so the guitar is dynamically reduced where the vocal has the most energy, helping both parts sit in the mix.

The plugin ships with 184 presets. Baby Audio says they were created by engineers including Craig Bauer, Max Jaeger, Preston Reid and Ryan 'Skinny' Shanahan.
