help me improve/increase volume of WAV file (attached) in Audacity
Dear Experts,
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!

For what my opinion is worth, I think you have done a very good job recording from cassette tape to WAV. I don't know if you used one of those commercially available cassette players with a USB interface, or whether you plugged the external output or headphone jack of a standard cassette player into the input of your PC audio card, but if it were me I would actually be pretty pleased with the results if I could capture the rest of the content just the way you have in the sample.
Noise removal is usually fairly hit and miss and it's very easy to accidentally remove some of the main audio content, especially in a very lengthy piece of audio that's far to long to "preview" the results without listening to the entire thing again and again. The good thing is that you have a man with a fairly consistent and monotone voice and a nice length of silence with hiss after the "please turn tape" prompt that can be used to get the noise profile namually or automatically.
I'm about to install Audacity again, as I haven't had it on this particular PC, and will look and listen later.

There is so many settings that can be changed during the playback in VLC with that little effects and filters sitting on the side.
Running Audacity in the background then recorded it in Audacity using the stereo mix ( what you hear in the speakers.
When you play them back which ever media player you use you have still some control over the treble side and bass side.
