Where is Addio.h?

I am looking at the Simple Audio player example and it includes the Library Audio.h.
However, I can't seem to find it. I have a Mac and have looked inside the application but still can't find it. Anyone know where it is?

C:\Users\YourName\Downloads\arduino-1.5.1r2-windows\arduino-1.5.1r2\hardware\arduino\sam\libraries\Audio. Hope this help

Thanks, I am on a Mac but that gave me enough of a clue as to where it is. For anyone on a Mac it is at:-
/Applications/Arduino 1.5/Arduino.app/Contents/Resources/Java/hardware/arduino/sam/libraries/Audio/Audio.h

Can I get the Audio Library from you guys. Please and Thank you.

No it is in your IDE already, no need to give it you as you already have it.

It is not an Audio libary it is the Addio.h file.
