Before doing this you might ask, “Why? What is the point?” Yes, the audible player is great. But, there are a few reasons why I prefer to move them to Plex.
- With Plex I can stream the audios to my my iPhone with the great Prologue app. This way I can listen to audiobooks without having to download them (but I can download them if I want). This saves a lot of storage on my phone and I don’t have to wait for a book to download before I start listening.
- This makes my books more easily available to my family. My wife once accidentally purchased an audiobook on her account. It was such a pain to try to figure out how to share it with me on Audible. Now my wife and kids all have access to the audiobooks I buy through their Plex account.
- There is just something gratifying about buying an audiobook and FEELING like you actually own it.
- Sometimes I purchase audiobooks that are not on Audible. This allows me to keep them all in one place so I don’t have to have multiple audiobook apps on my phone.
Go to Audible.com and then browse to your library. This will show all the books you have purchased. There is a download button next to each title to download the book in .aax format.
Convert the book to M4B
I am just going to point you to the AAXtoMP3 project on Github. Follow instruction there to get the tool set up.
This is the command I run to convert books to the format I want.
bash AAXtoMP3 --aac -e:m4b AUDIOBOOK.aax
Clip file (optional)
Since I’m not listening on Audible, like like to remove the beginning and ending of the clips that says “This is Audible” and “Audible hopes you have enjoyed this program”.
This is a little more tricky and requires a few tools to do so, so if you don’t want to go to the work of all this, just skip this step.
On the mac, both can be installed with brew.
brew install ffmpeg mp4v2
I have the following script that will do strip the intro and outro and keep the cover art intact.
# get cover art ffmpeg -i "$1" -an -codec:v copy cover.jpg # calculate duration to trim audible end clip dur=$(ffprobe -i "$1" -show_entries format=duration -v quiet -of csv="p=0") dur=$(echo $dur | cut -d "." -f 1 | cut -d "," -f 1) trim=$((dur - 6)) # main work to copy and trim ffmpeg -hide_banner -i "$1" -ss 2 -t $trim -map 0:a -c copy output.m4b # add the cover art back on mp4art -q --add cover.jpg output.m4b # housekeeping rm cover.jpg rm "$1" mv output.m4b "$1"
You would just pass the name of the m4b file to this script like so:
Serve from Plex
Now, just move this audiobook file to your plex server. I recommend this guide for configuring your Audiobook library on Plex.
Of course I have all this automated with Hazel so the only step I really need to do is download the .aax file and automation takes care of the test of it! But I won’t go into the details here. That would make for a much longer tutorial.
