This guide will work for both mp3 and m4b files, but I prefer chapterized m4b's. aax files, and converting them to chapterized. I plan on having a seprate walkthrough that will take you through backing up your Audible. Use a 3rd party Audiobook player app such as BookCamp or Prologue.Install the Audnexus Audible Metadata Agent in Plex.Ensure the ALBUM and ALBUMARTIST (or ARTIST) tags are set and correct.

(Optional) Convert mp3's to chapterized m4b.

Make the organizing and tagging as quick and painless as possible. Filter/browse/search by Narrator, Author, Genre, Year, Series, Rating, or Publisher. Show as much metadata as possible in Plex & Booksonic.

Edit the newly copied config files with your specific paths.

Download my example configuration files to Mp3tag's Appdata directory.

(Optional) Automatically convert mp3 audiobooks to chapterized M4B.

(Optional) Automatically copy untagged Audiobook files to a temp folder.

Most of it also works on Linux/Mac but the Mp3tag Audible WebSource script only works on Windows. Note: This guide targets and has been tested on Windows systems. While focused on Plex, if you follow the tagging and file processing steps you will also be compatible with Booksonic and AudiobookShelf servers.

Everything is customizable, and easy to change.

This guide is meant to serve as a framework for fully utilizing metadata. I'll be doing a deep dive into some advanced features of the tools available to us in order to get a nice, clean, and functional UI. This is my method for processing large libraries with bad/missing tags as quick as possible while getting the most metadata into Plex in the least amount of time. This guide is specifically for optimal Audiobook experience using Plex, which in it's current state only quasi-supports audiobooks.
