BaseAudioContext.destination - Web APIs 编辑

Value

An AudioDestinationNode.

Example

Note: for a full example implementation, see one of our Web Audio Demos on the MDN Github repo, like 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);
