Cria um objeto de áudio posicional.

Utiliza a [link:https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API Web Audio API].

Exemplo de Código


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

		// create the PositionalAudio object (passing in the listener)
		const sound = new THREE.PositionalAudio( listener );

		// load a sound and set it as the PositionalAudio object's buffer
		const audioLoader = new THREE.AudioLoader();
		audioLoader.load( 'sounds/song.ogg', function( buffer ) {
			sound.setBuffer( buffer );
			sound.setRefDistance( 20 );
			sound.play();
		});

		// create an object for the sound to play from
		const sphere = new THREE.SphereGeometry( 20, 32, 16 );
		const material = new THREE.MeshPhongMaterial( { color: 0xff2200 } );
		const mesh = new THREE.Mesh( sphere, material );
		scene.add( mesh );

		// finally add the sound to the mesh
		mesh.add( sound );
