How to Use

Activation Bytes

This will give you the activation bytes for your account, which you will need to decrypt your books

audible activation-bytes

Library Export

Export a list of all your audiobooks from audible to a CSV file

audible library export -f csv

Download your audiobooks

Download all your books

Note, this will also download any podcasts or similar, such as a NYT subscription

audible download --all --aax-fallback

Download a specific book

See the exported list for the book to ASIN number mapping (Can also be found in the web URL for a book)

audible download --aax-fallback -a {ASIN Number}

Remove DRM from Audiobooks

Install ffmpeg
```
apt install ffmpeg
```
Check the version, it must be at least version 4.5
```
ffmpeg -version
```
Create a folder to store decrypted books
```
mkdir drm-free
```

Remove DRM from all aax books in the current directory, storing them in the above directory

for i in *.aax; do ffmpeg -y -activation_bytes $(audible activation-bytes) -i "$i" -map_metadata 0 -id3v2_version 3 -codec:a copy -vn "./drm-free/${i%.*}.m4b"; done

AAXC files require a little more work to decrypt
1. Open the file that starts with the book name, and ends with “.voucher”
```
nano Book_Title-AAX_11_22.voucher
```
2. Make a note of the IV and Key (You may have to scroll down, it is under license_response)
3. Edit the following command, adding the IV, Key and AAXC file name
```
ffmpeg -y -audible_iv "IV Here" -audible_key "KEY here" -i "AAXC file name" -map_metadata 0 -id3v2_version 3 -codec:a copy  -vn "./drm-free/Book name.m4b"
```
4. Wait for the file to finish decrypting

Organize the books into folders

Install a tool for examining file metadata
```
apt install exiftool
```
Move into the DRM free folder
```
cd drm-free
```

Run the following command to create artist and book folders from the m4b files, then move the books into them:

for b in *.m4b; do mkdir -p "$(exiftool $b -Artist -s -s -s)/$(exiftool $b -Title -s -s -s)"; mv $b ./"$(exiftool $b -Artist -s -s -s)/$(exiftool $b -Title -s -s -s)"; done
