{{ domxref("AudioContext") }}的方法createConvolver()能创建一个{{ domxref("ConvolverNode") }}，通常用来对你的音频应用混响效果。在 Convolution规范定义 中查看更多信息。

-
- -

语法

- -
var audioCtx = new AudioContext();
-var convolver = audioCtx.createConvolver();
- -

返回值

- -

{{domxref("ConvolverNode")}}对象。

- -

例子

- -

下面的例子展示了一个 AudioContext 创建一个 混响器节点 的基本使用方法。基本前提是你创建一个包含声音样本的 AudioBuffer 用作混响环境 (称之为脉冲响应,) 和在混响器中应用。 下面的例子使用了一个简短的示例音乐厅人群效果,所以混响效果应用深度和回声。

更多完整例子请查看Voice-change-O-matic demo (中app.js的代码)。

- -
var audioCtx = new (window.AudioContext || window.webkitAudioContext)();
-var convolver = audioCtx.createConvolver();
-
-  ...
-
-// grab audio track via XHR for convolver node
-
-var soundSource, concertHallBuffer;
-
-ajaxRequest = new XMLHttpRequest();
-ajaxRequest.open('GET', 'concert-crowd.ogg', true);
-ajaxRequest.responseType = 'arraybuffer';
-
-ajaxRequest.onload = function() {
-  var audioData = ajaxRequest.response;
-  audioCtx.decodeAudioData(audioData, function(buffer) {
-      concertHallBuffer = buffer;
-      soundSource = audioCtx.createBufferSource();
-      soundSource.buffer = concertHallBuffer;
-    }, function(e){"Error with decoding audio data" + e.err});
-}

-ajaxRequest.send();
