A script to retrieve your activation data (activation_bytes) from Audible servers.

Last tested on Ubuntu 20.04 + Chromium 83.x + chromium-chromedriver (83.0.x) + Python 3.8.x in July 2020.

July-2020 update: folks have stolen this central principal component code + "IP" and have created a non-100%-free-source commercial product with it.


$ ./ -h
Usage: [options]

  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -d, --debug           run program in debug mode, enable this for 2FA enabled
                        accounts or for authentication debugging
  -f, --firefox         use this option to use firefox instead of chrome
  -l LANG, --lang=LANG  us (default) / au / in / de / fr / jp / uk (untested)
  -p PLAYER_ID          Player ID in hex (for debugging, not for end users)
  --username=USERNAME   Audible username, use along with the --password option
  --password=PASSWORD   Audible password

$ ./
<enter username and password>

$ ./ -l de  # for "de" users
<enter username and password>

$ mpv --demuxer-lavf-o=activation_bytes=CAFED00D sample.aax

$ echo -e "\ndemuxer-lavf-o=activation_bytes=CAFED00D" >> ~/.config/mpv/mpv.conf  # for convenience

$ ffplay -activation_bytes CAFED00D sample.aax

Quick Setup

Python 2 (or Python >= 3.6) is required along with Selenium, Requests, ChromeDriver, and Google Chrome.

pip install --user requests  # use "easy_install" if pip is missing

pip install --user selenium

Download and extract the correct ChromeDriver zip file from here to this folder.

Download Google Chrome from and install it on your computer.

Ryan reports that the 32-bit Mac ChromeDriver works fine under a 64-bit Mac environment.

Anti-Piracy Notice

Note that this project does NOT 'crack' the DRM. It simplys allows the user to use their own encryption key (fetched from Audible servers) to decrypt the audiobook in the same manner that the official audiobook playing software does.

Please only use this application for gaining full access to your own audiobooks for archiving/converson/convenience. DeDRMed audiobooks should not be uploaded to open servers, torrents, or other methods of mass distribution. No help will be given to people doing such things. Authors, retailers, and publishers all need to make a living, so that they can continue to produce audiobooks for us to hear, and enjoy. Don't be a parasite.

Debugging Tips

  • If you see an error message like "audible_error=Internal service error has occured while processing the request, please contact service admin" during the activation process, then contact Audible customer care and they will clear up your activation slots (there are 8 such slots).

  • If you see an "activation loop" in the official software (e.g. Audible Download Manager), then you are seeing the same exact problem (you activation slots are all used up).

  • Too many authentication attempts result in a temporary 30 minutes ban!

  • Use the following command to extract the SHA1 checksum from .aax files.

    $ ffprobe test.aax  # extract SHA1 checksum
    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x1dde580] [aax] file checksum == 999a6a...
    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x1dde580] [aax] activation_bytes option is missing!
  • In case of login problems use the ./ -d command to run the program in debugging mode and to login manually.

  • If you get an error in your terminal about selenium (such as selenium.common.exceptions.WebDriverException: Message: unknown error: call function result missing 'value'), make sure you have the most recent compatible chromedriver version. You may need to uninstall and reinstall it.

  • This program is pretty short and easy to debug. I cannot provide end-user support but I would be very happy to accept patches.

  • If this program does not work for you and all the debugging steps fail, then use the project to recover your "activation_bytes" in an offline manner. The good news is that you need to retrieve your "activation_bytes" only once.

  • Running wine AudibleGeneratePCPlayerID.exe multiple times under Linux can result in different outputs (different Player ID values). To get stable output run wine AudibleGeneratePCPlayerID.exe after running the "Audible Manager" program (Manager.exe) under Wine once.


  • It is possible to extract the "activation_bytes" from an existing 'AudibleActivation.sys' file.

    $ ./ AudibleActivation.sys

    You can grab the 'AudibleActivation.sys' file from various already-activated devices like Android phones, and Sansa music players.
