What is Audible AAXC Format?

Recently, all Audible books downloaded through the new Audible App for Android/iOS released on June 20, 2019 or later are saved in AAXC format instead of AAX/AA format. Audible said: "Basically, the new AAXC format is just the same format as the AAX format with an address copyright protection to avoid Audible files from being converted to any other format."

Why would Audible Adopt AAXC Format?

Confirmed in a phone call to Audible, AAXC is only applied to Audible books downloaded from the new Audible App released on June 20, 2019 or later. And the main purpose of adopting this new AAXC format is to prevent Audible books from being decrypted and converted to any other format. It's like an added protection on Audible contents to avoid some users to convert them. And the new AAXC format is not going to affect the way you listen to your audiobooks.
