Modifying audio properties
CocosDenshion provides functionality to change the pitch, gain, and pan properties of an audio source. Pitch is the frequency, gain is volume, and pan is a way to shift volume between left and right speakers. In this example, we will create a music-bending instrument to display these properties being dynamically modified.
