Audible fails for some reason. Audible fails for some reason.
I recently converted this script to bash instead of perl. Something about more people knowing bash or something rather.
Additionally I put some work into creating chaptered files as well as the mp3 version. A directory of structure GENRE/WRITER/TITLE
will contain the large mp3 as well as chaptered mp3s extracted from the AAX file metadata.
TODO: Automatically fix the MP3 tags on the generated audio files. For now I use easytag which seems to work okay.

## Requirements ## Requirements
* perl version 5.22.0 or later * bash 4.3.42 or later tested
* ~~perl version 5.22.0 or later~~ (Converted the script to bash for greater readability!)
* ffmpeg version 2.8.3 or later * ffmpeg version 2.8.3 or later
* libmp3lame (came from lame package on Arch, not sure where else this is stored) * libmp3lame (came from lame package on Arch, not sure where else this is stored)
You will also require the following perl modules:
* autodie
* Getopt::Long
* File::Basename
* IO::CaptureOutput
I would suggest installing cpanminus either through CPAN or (preferably) through your
distro's repositories. Take note that many perl modules can be packaged in your repos
as well so take a look there before resorting to cpan/cpanminus.
## Usage ## Usage
``` ```
perl AAXtoMP3.pl -a AUTHCODE -i AAXFILE -v bash AAXtoMP3.sh <AUTHCODE> {INPUT_FILES}
``` ```
* -a: **your** Audible auth code (it won't correctly decode otherwise) (required) * AUTHCODE: **your** Audible auth code (it won't correctly decode otherwise) (required)
* -i: the input AAX file to be converted (required) * Everything else is considered an input file, useful for batching!
* -v: verbose (optional)
