Aux input through Arduino Eleven?

Is it possible to take sound output from a phone/other device and turn it into a sound input on an Arduino Eleven? (which acts exactly the same as a Uno board) I have a "Sound and Piezo" module and a few aux cables and would prefer not to buy anything more.

It's possible to hook up alligator clamps to your aux cord and a wire so you can plug it into your breadboard, you can hook it up to your pizo that way

Where would I put said clamps?

Where would I put said clamps?

One on the end of the aux cord, and one end on the pizo pin
