Positional Audio

Create a positional audio object.

This uses the Web Audio API.

Code Example

// 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 );
