When talking about converting audible to mp3 open source, OpenAudible will be the first choice as it’s an excellent cross-platform audible audiobook manager used for downloading, viewing, converting audible to MP3, and organizing your aax files with the desktop application(Windows, Mac, and Linux).

Here are the steps that how I successfully convert audible to mp3 via OpenAudible on my Mac Big Sur.

Step 1. Download OpenAudible (v2.3.5).

I downloaded this app from openaudible official site, the latest version released is v2.3.5.

Download the dmg app and then right-click to open this app. I was told that the OpenAudible.app can’t be opened because Apple can’t check it for malicious software.

Then I click “Mac” -> “System Preferences” -> “Security & Privacy”, and “allow apps downloaded from App Store and identified developers”. Click on “Open Anyway” button and continue to install the OpenAudible.

Launch this app.

Note: OpenAudible had been free as an open source project for a long time, but now the available version we can download is 2.3.5 from its official website and it’s a shareware now (costs $12.00). Even though I downloaded the vesion 1.x from Github, after I launching it, I WAS told that I must update it.

Step 2. Connect OpenAudible to Audible and Download AAX.

Select Controls -> Connect to Audible.

Enter email and password to sign in Audible with your Amazon account (or audible account).

A new window will pop up, it shows our audible library. Close this window and back to OpenAudible window.

Note:

OpenAudible works in Audible US, DE, FR, and AU. It is not compatible with Audible IT and JP (Italy and Japan.)

Select “Quick Library Sync” and wait for moments.

Soon all my purchased audible titles are shown up at the bottom.

Select one book and right-click to “Download” this title. It’s also possible to bulk-download all the audible books.

OpenAudible starts downloading my audio file.

When I see “Ready to convert to MP3”, I know the downloading completed.

Tips:

If right-click and select “Show AAX”, the downloaded audible aax file location will open.

Step 3. Convert AAX to MP3 via OpenAudible.

Right-click and select “Convert to MP3”.

As what I introduced, now the OpenAudible is a paid software. If we want to convert audible aax to mp3, we must purchase a license.

Click the purchase link to finish one order and then input the license to activate it online.

Wait for the aax to mp3 conversion. Once finished, show MP3 then I find it.

OpenAudible helps store my audible books in one place, I really love it.
