Chapter 12. Using Audio Input and Output

In this chapter, we will learn how to generate sounds using examples of ways to generate sounds driven by physics simulation. We will also present examples of visualizing sound with audio reactive animations.

The following recipes will cover:

• Generating a sine oscillator

• Generating sound with frequency modulation

• Adding a delay effect

• Generating sound upon the collision of objects

• Visualizing FFT

• Making sound-reactive particles
