Mic Input
Get audio input from your computer's microphone. Make noise to float the ellipse.
Note: p5.AudioIn contains its own p5.Amplitude object, so you can call getLevel on p5.AudioIn without creating a p5.Amplitude.
To run this example locally, you will need the p5.sound library and a running local server.
