I have 8 hours of lectures from 1980s that I would like to digitize.
Please recommend me what kind of filters I should apply to make them sound better.
I did some learning of Audacity and I think I should:
1) remove noise - "Noise removal"
2) compress - "Compress dynamics 1.2.6" (external plugin) or "Compressor"
3) in the end, "Normalize"
I don't want to spend too much time learning Audacity since I will not use it regularly, that's why I chose the easier way - ask the Experts.
Please verify these steps, add extra steps, provide best parameters for filters etc.
I'm attaching one minute clip from training I'm digitizing so that you can recommend filter parameters etc.

Many thanks for your help!
