无法构造'AudioContext'：硬件上下文的数量达到最大值 [英] Failed to construct 'AudioContext': number of hardware contexts reached maximum

问题描述

有没有办法在我创建后删除 AudioContext ？

Is there a way to remove an AudioContext after I've created it?

var analyzers = [];
var contexts = [];

try {
   for(var i = 0; i<20; i++) {
      contexts[i] = new AudioContext();
      analyzers[i] = contexts[i].createAnalyser();
   }
}catch(e) {
   console.log(e);
   // too many contexts created -- how do I remove them?
}

我试过这个，但它不会让我创建新的上下文之后： analyzers.forEach（function（analyzer）{analyzer.disconnect（analyzer.context.destination）}）

I've tried this, but it doesn't let me create new contexts after the fact: analyzers.forEach(function(analyzer){analyzer.disconnect(analyzer.context.destination)})

我在Ubuntu Linux 14.04上使用Chrome 36。

推荐答案

你应该只有一个页面中的AudioContext 。

来自文档：在大多数用例中，每个文档只使用一个AudioContext。

From the docs: "In most use cases, only a single AudioContext is used per document."

我无法想到你曾经需要不止一个的原因。是否存在导致您创建多个上下文的特定问题？

I can't really think of a reason why you'd ever need more than one. Is there a specific issue you've run into that caused you to create multiple contexts?
