@ -12,33 +12,29 @@ your **personal** Audible account. The purpose of this software is to
|
||||
create a method for you to download and store your books just in case
|
||||
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.
|
||||
|
||||
## Setup
|
||||
You will need your four byte authitication code that comes from Audible's
|
||||
servers. This will be used by ffmpeg to perform the initial audio convert. You
|
||||
can obtain this string from a tool like [audible-activator](https://github.com/inAudible-NG/audible-activator).
|
||||
|
||||
## 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
|
||||
* 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
|
||||
```
|
||||
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)
|
||||
* -i: the input AAX file to be converted (required)
|
||||
* -v: verbose (optional)
|
||||
* AUTHCODE: **your** Audible auth code (it won't correctly decode otherwise) (required)
|
||||
* Everything else is considered an input file, useful for batching!
|
||||
|
||||
Tested on Linux with the above requirements. No effort will be made to
|
||||
port this work to any other operating system, though it may work fine. Want a Windows/
