This utility will take *.adh or *.aax files as provided by Audible, strip the DRM, and split them into chapters.
It will also attempt to locate metadata and orgaise the resulting files into a library.
Chapters will be split and the transcoding will run in parallel - one job per CPU thread.
You will need to have ffmepg installed on your system, and you will need to have your "activation bytes" to decrypt protected content.
