Class for loading an [link:https://developer.mozilla.org/en-US/docs/Web/API/AudioBuffer AudioBuffer]. This uses the [page:FileLoader] internally for loading files.
		// instantiate a listener
		var audioListener = new THREE.AudioListener();
		// add the listener to the camera
		camera.add( audioListener );
		// instantiate audio object
		var oceanAmbientSound = new THREE.Audio( audioListener );
		// add the audio object to the scene
		scene.add( oceanAmbientSound );
		// instantiate a loader
		var loader = new THREE.AudioLoader();
		// load a resource
		loader.load(
			// resource URL
			'audio/ambient_ocean.ogg',
			// onLoad callback
			function ( audioBuffer ) {
				// set the audio object buffer to the loaded object
				oceanAmbientSound.setBuffer( audioBuffer );
				// play the audio
				oceanAmbientSound.play();
			},
			// onProgress callback
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},
			// onError callback
			function ( err ) {
				console.log( 'An error happened' );
			}
