# [name]

Create a positional audio object.
This uses the [link:https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API Web Audio API].

## Example

[example:webaudio_orientation webaudio / orientation ]
[example:webaudio_sandbox webaudio / sandbox ]
[example:webaudio_timing webaudio / timing ]

`// create an AudioListener and add it to the camera var listener = new THREE.AudioListener(); camera.add( listener ); // create the PositionalAudio object (passing in the listener) var sound = new THREE.PositionalAudio( listener ); // load a sound and set it as the PositionalAudio object's buffer var 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 var sphere = new THREE.SphereGeometry( 20, 32, 16 ); var material = new THREE.MeshPhongMaterial( { color: 0xff2200 } ); var mesh = new THREE.Mesh( sphere, material ); scene.add( mesh ); // finally add the sound to the mesh mesh.add( sound );`
