What is an .AA file?
AA files are audiobook files saved in the Audible Audio format, a compressed audio format that Audible developed for distributing spoken-word content. Unlike music-focused codecs, the AA format is optimized for narration and supports audiobook features, such as bookmarks, chapter markers, and variable audio quality levels suited for long-form listening. Audible users commonly encounter AA files when downloading audiobooks, lectures, or audio programs purchased through the Audible platform.
You may find AA files on older Audible devices, in audiobook libraries synced through iTunes, or when accessing content downloaded before Audible transitioned to newer formats like AAX. Because AA files use digital rights management (DRM), they typically require Audible-compatible software or devices for playback. File Viewer Plus can open unprotected AA files and convert the audio to MP3 or M4A formats at various bitrates and sample rates, making the content accessible on a wider range of modern devices and media players.
