Thank you! My apologies for the delay in replying.
There are some issues that need to be fixed.
First the volume is too quiet at 83.5 DB. We aim for between 86 and 92 DB ~ ideally around 89 DB. You have some spikes, so you probably can not do a straight amplification. You would either have to deamplying the spikes and then amplify, or you can use the compressor option.
Also, the intro is missing - you said just "Chapter 3". And the outro is missing as well.
You can find the script for the intro and outro in the first post of this project.
If you could fix those issues and reupload, that would be great!
