Audio
Example
// create an AudioListener and add it to the camera var listener = new THREE.AudioListener(); camera.add( listener ); // create a global audio source var sound = new THREE.Audio( listener ); // load a sound and set it as the Audio object's buffer var audioLoader = new THREE.AudioLoader(); audioLoader.load( 'sounds/ambient.ogg', function( buffer ) { sound.setBuffer( buffer ); sound.setLoop( true ); sound.setVolume( 0.5 ); sound.play(); });
Constructor
