Audible book (in itunes) to use in my recording, any ideas?

Hi All
I am trying to use an audio book from Audible, now in itunes, in a recording.
The book doesn’t show up even though I have it in a Music playlist and shows up in itunes.
thanks for any suggestions

What about screen recording and than extract the audio with another app like sample creat or you can use the free app shortcut AudiofromVideo that should be a link i found in the audiobus forum.
