Beginners book says has Full Audio?

The beginners book introduction says " this book is filled with fun animation.... and a complete audio recording of the entire book so that you can listen as you follow along!" However, I do not see any type of audio button or anything else that indicates how to listen to the book on audio. Does anybody know what it is referring too? Gracias

The beginners book is not effective without some audio. Does an audio of any kind exist for this book or the exercises in it?

Where is the beginner's book? I can't seem to find it on here...

It can be found under Premium section 2 number 9 "Mega Spanish"
