destination 特性为 BaseAudioContext interface returns an AudioDestinationNode representing the final destination of all audio in the context. It often represents an actual audio-rendering device such as your device's speakers.

句法

baseAudioContext.destination;
					

值

AudioDestinationNode .

范例

注意 : for a full example implementation, see one of our Web Audio Demos on the MDN Github repo ，像 voice-change-o-matic .

var AudioContext = window.AudioContext || window.webkitAudioContext;
var audioCtx = new AudioContext();
// Older webkit/blink browsers require a prefix
var oscillatorNode = audioCtx.createOscillator();
var gainNode = audioCtx.createGain();
oscillatorNode.connect(gainNode);
gainNode.connect(audioCtx.destination);
