catch the resonances your EQ can't.

"really impressed, will dig in more. Smooth seems more surgical than Zynaptiq Unfilter. useful for taming harsh old recordings."

"I just discovered the kernaudio.io plugins. super precise and elegant. Kudos on this masterful work."

"SMOOTH is one of the few that is just already right in the ballpark as soon as you start applying the reduction. it starts doing the wanted taming while sounding very clean and natural. I own many resonance suppressors and so many of them take endless tweaking just to sound clean before you can even start dialing in the result you want."

"Soothe 3 from Oeksound is by no means the only resonance reducing processor on the market, and it's worth giving a shout out to both Baby Audio's Smooth Operator and Kern Audio's Smooth."

Jon Musgrave / MusicRadar (Plugin Week 2026)

"having all three together makes total sense. SMOOTH cleans up the resonances, WARM adds the character back, WIDE places everything in the stereo field. they complement each other really well."

"you've just simplified my whole approach and this works for how my brain works. I can now easily fix any issues and then use my other tools for focusing on the sound design/feel. it can become overwhelming when you have to have multiple eqs, compressors and clippers to fix stuff, which takes away from the fun part of mixing."

Daniel (lost fx) / bundle customer, July 2026

"just added both SMOOTH and WARM to my arsenal; both are excellent tools, great at what they do. my fave is SMOOTH; it has a tasteful, informative GUI, and works well with resonances, the way something like soothe2 does.. but for a fraction of the cost."

fisherKing / KVR (5-star review)

"They are focused to solve specific mixing issues without the needless options bloat. The controls are few and very specific about what they do. This makes it easy to learn the plugin and grab it to quickly accomplish what the plugin is supposed to do without interrupting my creative flow."

Jeffery / bundle customer, September 2026

"definitely great sounding plugins. definitely enjoying Smooth to tame unwanted resonances and frequency buildups, both on single tracks as well on the mix bus, without noticeable artefacts."

community member / Elektronauts

"SMOOTH is a very interesting professional resonance suppressor with many useful functions and a highly intuitive interface with a lot going on under the hood. its M/S capabilities turned out to be very effective in precisely smoothing out harsh resonances from center-panned sources, a feature I was missing in many other resonance suppressors."

MCCdusk / KVR (5-star review)

"I used WIDE and WARM on the guitar bus, and I feel like it became better than the original. WARM on the vocal bus really helped glue them together. I like the plugins a lot — they are in good shape and good state. Easily usable stuff."

Edizon / Plugin Demo Pt. 2 (March 2026)

"Wide, Warm, and Smooth are very good tools. Warm has an interesting take on the tape sound. they are easy to use and the Delta button is very helpful. you can quickly get something that works. I have other plug-ins that perform these functions, but these are excellent quality and easy to use. I am buying the bundle which is a pretty good deal at $59."
