2. Why does Audible Adopt AAXC Format?

Confirmed in a phone call to Audible, AAXC is the new format that Audible is now using through Audible app, which means all the audiobooks downloaded from the new Audible App released on June 20, 2019 or later are saved in the AAXC format.

In Europe it is not possible to download with computer audible files, so in Europe this program don't work with new audible files and in my opinion is not correct that the company continue to sell it without an upgrade !!
08/16/2019 08:44:02
Can you please tell me exactly the problem? Also, you can screenshot and show me the details via my email: epubor.iris@outlook.com. Then we will try our best to help you fix it.
08/16/2019 19:03:04
Audible in Europe, don't permit download from PC or Mac
08/16/2019 08:46:57
If you using a Windows 7, 8 or even 10 OS, first of all, please contact Audible Customer Support to ask them to "updated my download settings" because you can’t download Audible books via Audible Download Manager
08/16/2019 19:06:58
In Europe you can't do this
08/19/2019 10:21:53
Have you contacted the customer service about this issue? I think this is possible because we have many customers from Europe.
08/19/2019 17:55:13

Yes of course,I asked about to amazon /audible

In Europe you can’t download offline for sure

You can only in device, android, iOS, windows app, and in this case you have aaxc files… and all software like your don't works until now

You can’t with computers pc or Mac

If you can download audible books via  windows app, you will get aax format audible books. And the aax  books can be converted to mp3 format with Epubor Audible Converter.

Max you are using your PC wrong if you cant download them ok. Stop using IE and use a real browser like Chrome/Firefox. I have no trouble downloading my Audible Audiobooks - all 3000+ of them. If you are having trouble with downloading after you install Chrome, then try using the developers tab (by pressing F12) and then press Cnrl + Shift + M to bring up the device tool bar and select one of the various Android devices, refresh the page(F5)  if it doesnt automatically refresh, then click on the link for the audiobook, it should download just fine then.

On the Japanese audible, it is not possible to download AAX or AA files. Sadly you can only stream content. All the same the apps we have got can only download AAXC files. Do you think you will support converting directly from AAXC in the future? Thank you!
12/19/2019 10:17:56
We are working on this aaxc format. Once we have any progress, we will let you know. Thank you for asking.
12/16/2019 18:12:55
It is possible to download audibles in Europe !
I testes on tablet SAMSUNG. In app, there is possibility to choose between CLOUD, INTERNAL and SD.
Than, files are in folder ANDROID/COM.AUDIBLE.....
12/19/2019 10:17:08
Thank you for your comments and testing. Glad to know that.

When I downloaded a book the mp3 was for 10 minutes, not the 12 hours that the books it's supposed to be. i don't know what happened.
Please help! i followed all the instructions.
03/3/2020 08:45:04

Are you using the trial version? Please note that the trial version only converts 10 minutes of each files. So please upgrade the  audible converter to licensed version.

Any more problem, please feel free to let us know.

Downloading the book worked only with the Windows App (Europe). Unfortunately neither Epubor nor aax to mp3 converter converted the +400 MB audiobook in aax format correctly. Both converted only the first 10 minutes of the audiobook into mp3 (although epubor shows the correct length of the audiobook before converting)
05/26/2020 08:39:59

Thank you for contacting us. This is the trial limits. Please note the trial version only converts 10 minutes of each audible book. To obtain the full content of this book, please upgrade your audible converter to full license >>https://www.epubor.com/audible-converter.html

Any more problems, please feel free to contact us.

What is "address copyright protection"? I cannot find anything online which describes what this is.
06/15/2020 08:58:57
Thank you for asking. This means these audible books are protected by Audible DRM.
06/16/2020 11:01:15
Any luck with .aaxc format yet?
06/17/2020 08:48:16
Thank you for asking. We are still working on this aaxc format. Once we have any progress, we will let you know. Now it's highly suggested downloading your Audible books from computer as AAX/AA format and then use Epubor Audible Converter to convert them to MP3 for a backup.
06/21/2020 15:59:53
hmm... do let us know the moment that you crack the aaxc protections because i have both InAudible and OpenAudible, both of which work wonderfully on original AAX or AA files... coincidentally, i was playing around with an AAXC file, trying to get it working in one of the many audible conversion apps i use, and i renamed it .AAX instead, and guess what happened??? it showed all the book information in both OpenAudible and InAudible, including the purchase date and cover art, granted that thats all i could do in InAudible, but in OpenAudible conversion worked(for a minute or so) then gave me an error... i dont know if it helps you any but there you go...probably a stupid thing to try, but its sometimes the stupid tests that help the most... i had actually not noticed said book was in aaxc, or that it was currently uncrackable, so when i swapped it for a new book for free, i was stuck without a fully readable copy of the book...
06/22/2020 10:01:54
Thank you for contacting us. Please download your audible books not via audible for android or iphone, then you'll not get the audible books in aaxc format, but aa or aax format instead.

Now that Audible has "Audible Plus", you can only stream these titles on most platforms - there is no option to download them. The exception is on Android, where you can download them as AAXC, so at present, all "Audible Plus" titles have no way of being converted to MP3 (other than analogue recording).
12/24/2020 09:57:21
Thank you for your comments.
There is no way to remove audible plus audiobooks because they are the rented book. Please note Epubor software only supports the books your purchased, not rented.
Have a nice day!
05/7/2021 15:51:14
In other words... You don't have a converter for AAXC files.  That was a really long and confusingly worded way of saying it.
05/7/2021 16:10:05
Yes, there is no direct way to convert audible aaxc into mp3. But the way we offered is the easiest one.
Thank you for your understanding.

I've got audio book files with extension *.aaxc
I've tried your software EPUBOR Audible-converter V1.0.10.295 (free trial version - limited to first 10 min and no chapter) to test its abilities to convert my files.
First when i Click on +add button (the Drag and drop function didnot work with one of my sample)I've got only *.aax and *.aa format available but not *.aaxc.
Secund, when I choose anyway all files format *.* and choose my sample, I got the following message:

Unsupported format:
Please download Audible books on Windws/Mac.

Do the audio files input to your software have to be aax and not aaxc? All my audio books are aaxc downloaded from Audible app and all are only on my android smartphone
