I have a large audible library I would like to backup and make available for other audiobook apps that use less battery. I’d like to maintain as much information and structure as possible. I saw a self hosted solution for audiobooks I might try to implement as well.
What programs or processes work best for this?
What you’re looking for is a program called inAudible: https://github.com/rmcrackan/inAudible
It’s probably the best, there are other options, but nothing beats inAudible.
Ripping myself is what I did with Libation as suggested here. You log into your audible account when starting the software for the first time, your libary is shown and you can start to download.
When adjusting the auto tagging then audiibookshelf automatically sorts the stuff in the correct way with series etc.
Perfect combination and totally free.
