The AudibleManager is computer software that can be used to play and organise your library of audiobooks purchased from Audible. This audiobook manager and player can also be used to play regular MP3 files. You can easily import your favourite music into your library along with your audiobooks.
Open the AudibleManager.
Go to "File" and then select "Add Audio Files." You should see the Import Audio File window. This will let you browse through your computer and find an MP3 file.
Click the drop-down menu in the window to choose the location where your audio is stored. Once you have found the file, select it and then click "Import". You also can hold down the "Shift" key on your keyboard and select multiple files to import.
Go to your library, click on the MP3 file you have just imported, and click "Play" to listen to the file.
