Michael Wynne, an audio mastering engineer, just claimed on his In The Mix channel: I Found The Best FREE AI Noise Reduction Plugin in 2023.

The tool is a free AI de-noising and re-reverb plugin called GOYO by South Korea’s Supertone AI.

Michael begins:

“I’ve used many of the sort of more premium and expensive dialogue, restoration and denoising softwares, and those are very good, but I haven’t come across a free tool that even comes close to what is offered by those. So I was really curious, downloaded it, tried it in my DAW and video editor, and was just completely shocked by the results.”

There are three dials: Ambience, Voice and Voice Reverb. You can solo, mute, decrease or increase each band. Simple and powerful!

His expert tip:

“My favourite way to use these sorts of tools is to dial them in and then print the results. So I would control this to the amount I’d like. I would export that as a new WAV file, take a listen and then work with that so that I know that the next time I open up the session, it’s going to be exactly the same.”

The How to Use page from Supertone is quite sparse so Michael’s examples are great.

My take: the perennial joke on set has always been, “We’ll fix it in post.” Well, now that’s possible for sound! I’ve used this on a short and can attest to its ease of use and incredible results. I concur with Michael that it’s best to print out each voice track as a WAV file and re-synchronize it to the timeline because I found that either the effect did not persist between sessions or the values had reset to zero or the effect was present but the numbers displayed as zero. My other tip is to only use the graphical user interface (and do not use the Inspector) as this seemed to work best. After all, this is a free beta!
