/**
 * The AudioListener represents a virtual listener of the all positional and non-positional audio effects in the scene.
 * A three.js application usually creates a single instance of AudioListener. It is a mandatory construtor parameter for audios entities like Audio and PositionalAudio.
 * In most cases, the listener object is a child of the camera. So the 3D transformation of the camera represents the 3D transformation of the listener.
