As an Audible member, you can listen to high-quality audiobooks online or offline with an authorized smartphone, tablet, or computer. But sometimes you might run into trouble like this: You kept receiving an error saying "file format is not supported" when trying to play the Audible AAX file with your VLC or MP3 player.

The reason is that your device is not compatible with the AAX format. Actually, the Audible audiobooks are all DRM protected; that is to say, they can only be played on a few Audible-compatible devices. So, what to do when you want to listen to audiobooks on devices other than the authorized ones? You might need to use an AAX to MP3 converter to convert Audible AA/AAX to MP3. It's the simplest solution for using your Audible file easily.
