RESO | Fix Harsh Resonances

I work daily with independent artists and filmmakers whose projects are often recorded in less-than-ideal spaces, with modest gear and no access to pristine studios. As a result, nearly every session I open is full of resonance issues—drum tracks plagued by unpleasant room nodes, DI’d guitars spiking through amp sims, or dialogue captured on resonant lav mics.

Until now, I’ve relied on the traditional EQ sweep: hunting down resonances one by one and cutting manually. Reso doesn’t reinvent that process—it perfects it. Every detail of the workflow has been intelligently optimized. The interface is sleek and deceptively simple, but beneath it is evidence of real, thoughtful design—clearly made by musicians and engineers who live in the trenches of real-world audio.

The sonic results are outstanding. Cuts feel natural and transparent, without the harshness or “ringing” side-effects that high-Q notches on conventional EQs can leave behind. The ability to deploy so many nodes in a single instance is a lifesaver; with standard EQs I often had to chain multiple plugins, but Reso handles even extreme cases effortlessly.

And the time it saves? Immense. What once took me 10-15 minutes per track is now done in 2-3 minutes, freeing up precious time for me to focus on creativity instead of technical firefighting.

For anyone tempted to compare it directly with Soothe 2—don’t. They’re designed for completely different use cases, and both deserve a spot in the modern engineer’s toolkit.

In short: Reso delivers on a need I’ve had for decades. It’s transparent, efficient, intelligently designed, and genuinely indispensable. If I could give it more than five stars, I would. Bravo to MasterTheMix for creating one of the most genuinely useful plugins in years.

thanks

I had some resonances in certain mix ranges that I couldn't pinpoint directly, so I had to search track by track for the frequency that was causing the problem. I tried RESO out of curiosity to see how effective it was, and you know what? Now I can't do without it. This plugin helps you locate resonance points in seconds, and you can also modify them as you wish. It's also a very useful tool for mastering. Honestly, well done to MTM!

This plugin has revolutionized my mix, eliminating annoying resonances with surgical precision.

I had a deadline and needed to master quickly here in the studio... works very well in real time (if you have enough memory in your Mac). Amazing results, very finely adjustable and approved for production ( Libreville Productions ) Paris.
