The purpose of this software is to convert AAX (or AAXC) files to common MP3, M4A, M4B, flac and ogg formats
through a basic bash script frontend to FFMPEG.
Audible uses this file format to maintain DRM restrictions on their audio
Audible uses the AAX file format to maintain DRM restrictions on their audio
books and if you download your book through your library it will be
stored in this format.

Audible fails for some reason.
## Requirements
* bash 4.3.42 or later tested
* bash 3.2.57 or later tested
* ffmpeg version 2.8.3 or later (4.4 or later if the input file is `.aaxc`)
* libmp3lame (came from lame package on Arch, not sure where else this is stored)
* grep Some OS distributions do not have it installed.
* sed Some OS versions will need to install gnu sed.
* jq Command-line JSON processor
* libmp3lame - (typically 'lame' in your system's package manager)
* GNU grep - macOS or BSD users may need to install through package manager
* GNU sed - see above
* GNU find - see above
* jq - only if `--use-audible-cli-data` is set or if converting an .aaxc file
* mp4art used to add cover art to m4a and m4b files. Optional
* mediainfo used to add additional media tags like narrator. Optional
## OSX
Thanks to thibaudcolas, this script has been tested on OSX 10.11.6 El Capitan. YMMV, but it should work for
conversions in OSX. It is recommended that you install GNU grep using 'brew install grep' for chapter padding to work.
## AUR
Thanks to kbabioch, this script has also been packaged in the [AUR](https://aur.archlinux.org/packages/aaxtomp3-git/). Note that you will still need to extract your activation bytes before use.
