Two sounds by AudioGenerator at the same time

Question

I am learning how to generate/combine sounds using Mathematica in order to show that sounds cancel at some phases. As an exploratory example, I have

AudioGenerator[{"Sin", 44, 0}, 5]

and

AudioGenerator[{"Sin", 44, Pi}, 5],

which I want to play together to see if these cancel.

Answer 1

a1 = AudioGenerator[{"Sin", 44, 0}, 1]
a2 = AudioGenerator[{"Sin", 44, \[Pi]}, 1]

AudioOverlay[{a1, a2}]
