Dynamic Resonance Suppressor
RESO is a dynamic resonance suppressor that helps you quickly identify and resolve resonances in your audio.
When resonances build up to an excessive level, your music can sound harsh and unpleasant, often masking other elements that you actually want to hear. But, applying broad resonant reduction across your whole mix can take away the character of your audio, and if you apply too much reduction you’ll make the mix sound thin and reduce the punch of your transients.
RESO helps you identify which specific frequencies have a build-up of energy relative to your whole mix. It also guides you on how much reduction is needed to dynamically resolve the resonance without overdoing it. The high-quality filters deliver mastering-grade transparency, with automatic Q optimization to give you the most musical results.
There simply isn’t a faster or more effective way to musically resolve resonant issues in your mix.
Cleaner Mixes in Less Time
Use RESO on any Channel

RESO can be used to resolve the resonances of any channel in your mix, whether it’s a vocal, a synth, percussion, busses, or your mastering chain.
Analyze Your Audio

Look for disproportionately high peaks in the visual display.
Use the Frequency Sweep to help you identify resonances that sound unpleasant.
The Calculate Targets feature will locate the most resonant frequencies and give you targets so you can resolve the resonances transparently.
Tweak To Perfection

Creating a node is as easy as clicking anywhere on the interface.
Position the node at the peak level at which you want the resonance suppression to start and scroll to adjust the Q.

Reviews Summary
While it aims to provide a helpful overview, it may not capture every perspective or detail. We encourage you to read individual reviews to make an informed decision.
Users highly praise this resonance-taming plugin for its effectiveness, flexibility, and affordability compared to competitors like Soothe. It excels at soothing harsh frequencies and annoying single resonances, offering both subtle and aggressive results that speed up sound design. While the auto-detection feature makes it simple and easy to use, reviewers note that manual mode has a slight learning curve and caution against over-processing real instruments to preserve their character.
