使用网络音频创建自定义回声节点 [英] Creating a custom echo node with web-audio

问题描述

我正在使用 webkit Audio API 并尝试创建一个回声效果，以实现我在循环中将 DelayNode 与 GainNode 连接起来(一个的输出是另一个的输入，反之亦然).

I'm playing with the webkit Audio API and I'm trying to create an Echo effect, to accomplish that I've connected a DelayNode with a GainNode in a loop (The output of one is the input of the other, and viceversa).

效果很好，但现在我想创建一个 EchoNode 对象，我可以插入它并与其他 AudioNode 对象连接.

The effect works fine, but now I want to create an EchoNode Object that I can just plug-in and connect with the other AudioNode objects.

类似于:

myEchoNode = new EchoNode(); 
myConvolverNode = context.createConvolver();
myConvolverNode.connect(myEchoNode);

我认为我应该让我的 EchoNode 从 AudioNode 继承，以便其他每个 AudioNode 的连接功能都可以工作，但我不知道如何使用 web Audio API 在 Javascript 中做到这一点.

I think that I should make my EchoNode inherit from AudioNode, so that the connect function of every other AudioNode would work, but I don't know how to do that in Javascript with the web Audio API.

谁能给我一个提示，或者如果您认为有更好的方法来完成，我将不胜感激.

Can anyone give me a hint, or if you think that there is a better way to accomplish that I would greatly appreciate it.

谢谢
