AAXC – New Format for Protecting Audible Audiobooks

The AAXC file extension is a new data file format associated with Audible audiobooks. AAXC file extension was developed by Audible which is the enhanced format of AAX or AA. All Audible audiobooks downloaded from the new Audible app for Android or iOS are ended in the new format of AAXC instead of AAX or AA since June 2019. Files in AAXC format can be opened with the Audible app on portable devices.

Why Audible Uses the New AAXC Format?

At present, the new format is only applied to the audiobook downloaded from the Audible app for Android and iOS. The purpose of adopting this new AAXC format is to prevent Audible audiobooks from being decrypted. However, Audible does not support many devices or services until now. To play Audible books on devices or services that do not get Audible admittance, most Audible listeners will choose to convert Audible to MP3. MP3 is the most popular audio format. Here are some features of the MP3 format and why you need to convert AAXC to MP3.

1. MP3 is one of the most compatible audio formats. If you convert Audible AAXC to MP3, it is pretty easy for you to transfer Audible books.

2. MP3 files can store ID3 tags such as genre, title, and more. So you can keep the info after converting AAXC to MP3.

3. MP3 files are in small size so that you can use less space to store your Audible books.

Note: Even though you rename the extension of the file in the format of AAXC, you still cannot change the original file type. Only special conversion software can change a file from one type of file to another.

Save Audible Audiobooks as AAX Rather than AAXC

Fortunately, the new format is only adopted on all audiobooks downloaded from the mobile Audible app. The AAXC container format is the same as the Audible AAX format while it uses a different encryption scheme. So you can switch to download Audible books in AAX format without worrying about the quality problem. You could achieve audiobooks in the format of "Enhanced" (.aax) from Audible's official website.
