Opening aax files

Have a problem opening a .aax file? We collect information about file formats and can explain what aax files are. Additionally we recommend software suitable for opening or converting such files.

What is the .AAX file type?

The .aax extension is bound up with the proprietary Audible Enhanced Audio (AAX) format and is found in AAX audio files. AAX has been developed and introduced by Audible, Inc., a division of Amazon, as an extension and replacement of the AA audio book format. Internally, AAX uses the AAC audio compression codec.

An .aax file is an audio book file in the AAX format. Unlike the earlier AA format, AAX has stronger DRM features and supports in-story displayable graphics when played on screen-based devices. AAX also provides generally higher sound quality.
