help with fixing bad audio on youtube video

as a newbie i’m unsure if this is the right thread so i am prepared for reprimands… but also help :slight_smile:
the problem is the audio quality of the video on [url][/url] , obviously i do not expect whoever can help to do a complete remaster of the audio track - just a hint/trick/tip to get me in the right direction will be more than welcome and will also benefit my understanding.
thanking you in advance
God bless

You’ll need a miracle to cure that level of echo & reverberation.

Installing a De-reverb plugin can mitigate the problem, but they’re no cure, (and not free) …
