Audiobookshelf expects audiobooks organized into Author/Title/ folders. You don't need to do this yourself — Terrarium handles it.
How to upload
- Go to your Terrarium dashboard and click the Files tab
- Under My Audiobooks, drag your audiobook files onto the drop zone
- Wait for the upload to finish
- You'll see "Organizing files..." while the organizer runs
The organizer reads each file's metadata (author, title) using ffprobe and moves it into the right folder structure. If the file doesn't have metadata tags, it falls back to parsing the filename.
Once organized, open Audiobookshelf and your books will appear. You may need to trigger a library scan from Audiobookshelf's settings if it doesn't pick them up immediately.
Supported formats
Audiobookshelf plays M4B (the standard audiobook format), MP3, M4A, and most other audio formats. M4B files are ideal because they contain chapter markers.
File size
Audiobooks are large — a single book is typically 200 MB to 1 GB. Your Audiobookshelf instance has 10 GB of disk space. Keep an eye on usage in the Files tab.
