This is a tough problem. It's not room noise that you're trying to get rid of, it's room reverberation.

EQ isn't going to help here.

Neural networks trained to remove noise - like Waves Clarity - won't, because reverberation sounds like vocals.

Neural networks trained to isolate vocals - like Spleeter - also hear the reverb as part of the vocal.

I know, because I tried them both. cry

You need to use de-reverberation software to fix this kind of problem, something like this:

No matter what program you use, it'll be adding some artifacts the the audio. So there's a balancing act between reducing reverb and losing audio quality.

These programs can be pretty pricey, but are often available for downloading as time-limited demos, so I suggest that's the best option.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
