opencore-amr-js's Issues

支持微信浏览器吗？（在微信里打开网页后播放amr）

如果能就太牛逼了！因为微信jssdk支持录音，然后录完就可以不用转码直接播放了！

不过刚才试了一下你的demo好像不行。。。

opencore-amr-js该项目是否已经停止维护？

你好，作者，很感谢作者编译出来的JS版本供我们使用，目前发现在项目中仅支持amr-nb格式的解密，想咨询一下作者关于amr-wb格式的如何编解码，有看到他人文章说官方版是包含amr-wb格式的解码，请问作者是否有继续维护此项目的计划？

process.argv[1] is undefined when ENVIRONMENT_IS_NODE

Using this lib in nw.js where it is node env but the process.argv[1] is undefined, causing an Error:

Uncaught TypeError: Cannot read property 'replace' of undefined

// hack to fix bug and it works
// Module["thisProgram"] = process["argv"][1].replace(/\\/g, "/");
Module["thisProgram"] = process["argv"][1] && process["argv"][1].replace(/\\/g, "/");

Any idea? Thanks!

Should have only one AudioContext per page

Failed to construct 'AudioContext': number of hardware contexts reached maximum (6)

see: http://stackoverflow.com/a/25046735/3855809

https://github.com/yxl/opencore-amr-js/blob/master/js%2Fdemo.html#L132

var ctx = new AudioContext(); should be moved to outer scope to keep

Published on NPM(Node Package Manager) ?

Dear @yxl
This project is awesome.
Could I suggest that you publish this onto npm as a node module so that we can require in as an external package?
Currently, there is no such lib found on the site. https://www.npmjs.com/search?q=amr+js
