是否可以使用 JavaScript 在浏览器中播放合成声音？
我刚刚在互联网上发现了一个 完全用 JavaScript 编写的任天堂模拟器，但它没有声音。这让我开始思考：有没有办法使用 JavaScript 在浏览器中合成声音然后播放？如果一般情况下不可能，那么是否有 Safari/Opera/FireFox/IE/Etc。使之成为可能的扩展？
我不是在询问合成声音的技术，只是询问播放由浏览器中运行的代码合成的声音的技术。
I just came across a Nintendo emulator written entirely in JavaScript on the interwebs, but it doesn't have sound. It got me thinking: Is there any way to synthesize sound in the browser using JavaScript and then play it? If it's not possible in general, then are there any Safari/Opera/FireFox/IE/Etc. extensions that would make it possible?
I am not asking about techniques for synthesizing sound, just techniques for playing sounds that have been synthesized by code running in the browser.

我想你最好的选择是让 Javascript 使用ExternalInterface (http: //www.adobe.com/devnet/flash/articles/external_interface.html）。 Flash 现在有一种在声音缓冲区和通用 ByteArray 类之间传输数据的方法。

您可以使用 Flex SDK 免费开发 Flash http://www.adobe.com/产品/柔性/。
I would imagine your best bet is to have Javascript talk to Flash using ExternalInterface (http://www.adobe.com/devnet/flash/articles/external_interface.html). Flash now has a way of transfering data between the sound buffers and a general purpose ByteArray classs.

You can develop Flash for free using the Flex SDK http://www.adobe.com/products/flex/.
大多数开发人员想要使用 JavaScript 添加声音到应用程序时，都会使用 SoundManager 2。它具有挂钩，因此 JavaScript 可以与 Flash 8 和 9 功能进行交互。我不确定它是否暴露了使用字节数据的能力，我猜你正在追求这一点，我从来没有处理过这个问题。
Most developers use SoundManager 2 when they want to add sound to their application with JavaScript. It has hooks so JavaScript can interact with Flash 8 and 9 features. I am not sure if it has exposed the ability to work with Byte Data which I guess you are after, I never had to deal with that.
原来NES模拟器的作者找到了一个动态音频库：

我还没有尝试过，但文档看起来很有希望：
It turns out the author of the NES emulator has found a dynamic audio library:

I haven't tried it, but the docs look promising:
理论上，应该可以合成声音，然后让浏览器使用数据 URL 来播放它们。
在实践中，Steven Wittens 实际上制作了一个演示技术。
encodeAudio8bit和encodeAudio16bit函数是神奇发生的地方。In theory it should be possible to synthesize the sounds and then get the browser to play them using a data URL.
In practice, Steven Wittens has actually produced a demo of this technique. The
encodeAudio8bitandencodeAudio16bitfunctions are where the magic happens.
