How to Convert AAXC to MP3 for Free

Part 1. What Is an AAXC Format?

AAXC is a special kind of audiobook file developed by Audible. It's made to keep audiobook content safe from piracy and unauthorized sharing. This format ensures that audiobooks you buy or download from Audible are kept secure and can only be listened to using authorized methods. The encryption used in AAXC files stops users from easily sharing or moving audiobooks between different devices or platforms.

How to Get AAXC from Audible:

You can get AAXC audiobooks from Audible on your phone, whether it's Android or iPhone. But on iPhones, finding these files is tricky due to iOS's rules, which make it hard to access certain file locations without making changes to your device. Even if you stop using Audible, you can still listen to the AAXC audiobooks you've got.

To find AAXC files on Android:
Go to: Files\Internal storage\Android\data\com.Audible.application\files.

How to Get AAX Instead of AAXC from Audible:

The AAXC format is a new Audible encryption format, meant to replace the old AAX and older AA. Usually, you'll receive AAXC files from Audible, especially on Android devices. But if you prefer AAX files, you can still get them on the Audible website using a computer. It's important to know that AAX files also have DRM protection, just like AAXC files. However, it's generally easier to convert AAX files to other formats like MP3.

Follow these steps:

1. Go to audible.com using a browser.
2. Log in.
3. Go to your Library.
4. Click Download next to the audiobook you want. Then you'll have the AAX file instead of AAXC.

If you're on Linux and looking to convert AAXC files to MP3, you can use a free and open-source called "aaxtomp3." This tool leverages the audible-cli package, which handles the decryption of both AAX and AAXC files by storing the necessary keys when downloading the audiobooks. Here's how you can use it:

Step 1Install Requirements

Before you begin, ensure you have the necessary tools and packages installed:

• bash (version 3.2.57 or later)
• ffmpeg (version 4.4 or later if the input file is .aaxc)
• libmp3lame (typically 'lame' in your system's package manager)
• GNU grep, sed, find
• jq (only if using --use-audible-cli-data)
• mp4art (optional, for adding cover art to m4a and m4b files)
• mediainfo (optional, for adding additional media tags like narrator)

Step 2Download aaxtomp3

You can obtain the aaxtomp3 tool from its source repository or through package management systems like apt or yum. Follow the installation instructions provided with the tool.

Step 3Convert AAXC to MP3

Once installed, you can use the aaxtomp3 tool to convert AAXC files to MP3. Here's a basic usage example:

      bash AAXtoMP3 [-e:mp3] <AAX/AAXC INPUT_FILES>...
    

Replace <AAX/AAXC INPUT_FILES> with the path to your AAX or AAXC files.

If you want guided assistance through the conversion process, you can use the interactive mode:
