I use Nvidia's Broadcast tool to do it locally on my GPU in realtime. It works fairly well and has made some older videos, especially courses or presentations at conferences satisfactory to watch but I agree it would be great if YouTube could automatically provide it as a tool as well.
I'm hoping to find a tool that removes umms and ahhhs, mouth clicks and other annoying tics.
There was a java tool that could improve audio but it was designed for archival of tape, film audio, and old records and the like. I lost the computer i ran it on, i even paid for it but i can't find the receipt to redownload (or even rebuy it). It worked very well - about as well as i can do manually, and perhaps a few percent better - i don't remember many shimmering artifacts https://www.youtube.com/watch?v=xazubVJ0jz4&t=85s [0]
I'd be pleasantly surprised if nvidia can "fix" audio, as i have.. oh, a few thousand hours of audio that i could clean up in an automated way.
[0] hilariously, youtube gave me a copyright strike for this video, even though it's obviously an archival upload. Jerks.
