aax_to_ogg's Introduction

Overview

What is it?

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.

What does it need?

You will need to have ffmepg installed on your system, and you will need to have your "activation bytes" to decrypt protected content.

Usage

$ python3 -m aax_to_ogg
usage: aax_to_ogg [-h] [-a ACTIVATION_BYTES] [-b BITRATE] [-p PARALLEL]
                  [-d DOMAIN] [-l LIBRARY] [-s] [-i SNIP_INTRO_LEN]
                  [-o SNIP_OUTRO_LEN] [--debug]
                  files [files ...]
