## What it is
AAXtoMP3 is a bash script CLI frontend to FFmpeg that converts Audible AAX/AAXC audiobook files into MP3, M4A, M4B, FLAC, or Ogg/Opus. It is intended for backing up audiobooks from your own Audible account by removing the DRM restrictions Audible applies to downloaded files.

## Use cases
- convert audible aax files to mp3
- remove drm from my audible audiobooks for backup
- convert aaxc audiobooks to m4b with chapters
- batch convert a whole folder of audiobooks to flac or opus
- split an audiobook into per-chapter audio files
- scriptable command-line audiobook converter using ffmpeg

## When to choose
- You own audiobooks on your personal Audible account and want DRM-free local copies in case the service goes away
- You want a lightweight, scriptable batch converter that only needs bash and ffmpeg
- You need flexible output formats (MP3, M4A/M4B, FLAC, Ogg/Opus) with options for chaptered files, cover art, and target directories

## When to avoid
- You want a graphical interface rather than a command-line script
- You need to process audiobooks not on your own Audible account - the tool explicitly does not support that
- You need Windows-native support without a bash/GNU-tools environment such as WSL
- You expect frequent updates or active maintenance - the latest release dates to March 2023
