Audiblex

Audible aax audio book to M4A, M4B and MP3 converter which actually works.

It works by extracting the audio book checksum, looking up it's activation bits in a rainbow table and converting to the specified format.

Platform

The script is only tested on Linux x64.

Requirements

• Python 3
• ffmpeg for converting

Install

sudo ./install.sh

Usage

positional arguments:
  file                  The aax file to convert

optional arguments:
  -h, --help            show this help message and exit
  -t TYPE, --type TYPE  The destination filetype M4B, M4A or MP3
  -a ACTIVATION, --activation ACTIVATION
                        Define the activation bits to use
  -s, --single          Convert to a single file
  -l, --lookup          Lookup the activation bits in the rainbow table
  -c, --clear           Clear the activation bits cache

Examples

# Convert book to M4A and auto lookup activation bits
audiblex BOOK.aax

# Just lookup the activation bits without converting
audiblex BOOK.aax -l

# Use 'a1b2c3d4' as activation bits and convert
audiblex BOOK.aax -a a1b2c3d4

# Convert to single file of type 'MP3'
audiblex BOOK.aax -s -t MP3

Thanks to

r15ch13 for the rainbow table and jostyee for the file converters.

Future

• Could be nice to not be depended on the file converter binaries and just use ffmpeg directly.
• Could also be nice to not need the rainbow table binaries and convert tables to something python could read.
