Welcome to /c/piracy
No netflix or streaming services landlubbers allowed, this is pirates territory.
It costs like $20 I think, but completely worth it. It connects to your audible account, syncs the books locally, then rips out the drm and converts them to the open source m4b format.
Then you can and should create torrents for them, so others can seed.
This is the only method out of maybe a dozen I have tried over the years that worked for me. Well worth the money
Ya it works very well. I'm surprised there aren't more people doing this and creating torrents for them. We need to get the entire amazon library on torrents 🤣
