Question

创建一个位置相关的音频对象.

使用了Web Audio API.

代码示例

// 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 );

例子

webaudio / orientation
webaudio / sandbox
webaudio / timing

构造函数

PositionalAudio( listener : AudioListener )

listener — (必须) AudioListener 实例.

属性

Audio类的继承属性.

.panner : PannerNode

位置相关音频的PannerNode.

方法

Audio类的继承方法.

.getOutput () : PannerNode

返回panner.

.getRefDistance () : Float

返回panner.refDistance的值.

.setRefDistance ( value : Float ) : PositionalAudio

设置panner.refDistance的值.

.getRolloffFactor () : Float

返回panner.rolloffFactor的值.

.setRolloffFactor ( value : Float ) : PositionalAudio

设置panner.rolloffFactor的值.

.getDistanceModel () : String

返回panner.distanceModel的值.

.setDistanceModel ( value : String ) : PositionalAudio

设置panner.distanceModel的值.

.getMaxDistance () : Float

返回panner.maxDistance的值.

.setMaxDistance ( value : Float ) : PositionalAudio

设置panner.maxDistance的值.

.setDirectionalCone ( coneInnerAngle : Float, coneOuterAngle : Float, coneOuterGain : Float ) : PositionalAudio

这个方法用来把环绕声音转换为定向声音directional sound.
