AudioListener

The AudioListener represents a virtual listener of the all positional and non-positional audio effects in the scene.
A Verge3D 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.

Code Example


    // create an AudioListener and add it to the camera
    const listener = new v3d.AudioListener();
    camera.add(listener);

    // create a global audio source
    const sound = new v3d.Audio(listener);

    // load a sound and set it as the Audio object's buffer
    const audioLoader = new v3d.AudioLoader();
    audioLoader.load('sounds/ambient.ogg', function(buffer) {
      sound.setBuffer(buffer);
      sound.setLoop(true);
      sound.setVolume(0.5);
      sound.play();
    });
