Convert .MP3 to .AA
Not directly possible
AA is the proprietary audiobook format that Audible creates. A normal converter cannot turn an MP3 into an AA file, and Audible does not offer a tool for listeners to do so.
What to do instead
- Play MP3 audiobooks in any player; apps that support chapters work well with the M4B format.
- Convert the MP3 files to M4B (AAC with chapters) if you want a proper audiobook file.
- Authors who want to publish an audiobook on Audible must use Audible’s publishing service (ACX).
