.AA files are audiobook files distributed from Audible and iTunes are fairly integrated and iTunes allows for the playback of these file formats. In order to convert the files to a DRM-free MP3 format, one must import the .AA files into iTunes, create an audio CD and subsequently reimport the files off the CD using iTunes built-in MP3 encoder. It is a bit of a run around, but it gets the job done.

  1. 1

    Import your .AA file into iTunes. You may need to authorise your Audible account via the Advanced menu in iTunes.

  2. 2

    Create a new playlist, and name it after the title of the audiobook. Drag the audiobook into the playlist.

  3. 3

    Insert a blank CD and select "Burn Disc" from within the playlist. Select your cd burning drive and select Audio CD as the format and confirm. iTunes will begin burning the disc. Depending on the speed of your drive it can take up to a half hour to burn the audiobook files to CD. Once complete, eject the CD.

  4. 4

    Open up iTunes' Options (Preferences on Mac) via the File menu. Under the General tab, select "Import Settings..." and make sure Import Using is set to "MP3 Encoder." You can adjust the quality settings as you wish. Select "OK" to save the settings and exit the Options window.

  5. 5

    Reinsert the burnt audiobook CD into your computer. It will show up in your iTunes sidebar. Select it.

  6. 6

    Select "Import" while viewing the contents of the CD in iTunes to import the audiobook into your iTunes library in DRM-free MP3 format.

Tips and warnings

  • Use the MP3 format only to listen to your audiobooks on devices not compatible with the .aa format. Do not use this method to illegally distribute the copyrighted material.
