Can I improve audio of a speech entirely - not interested in training

[Furkan Gözükara]

Hello. I have full lectures on my youtube channel

E. G. A lecture : https://youtu.be/XLsrsCCdSnU

I want to improve audio quality

What script do I need to provide for improving entire speech without any trimming? I need to keep it snyced with video

I can extract audi as wav with ffmpeg

are there only 1 pre trained model? If not which pre trained model is best?

I can setup and install with depensincies

But before spending time I want to learn possible to improve long recordings or not and what inference command is necessary

Thank You so much
