测试在iframe里面请求录音权限的兼容性。最佳实践应该是让window.top(不适用于跨域)去加载Recorder，iframe里面使用top.Recorder；此测试未遵照此最佳实践，以模拟跨域iframe和同域下的复杂真实情况，跨域时未设置相应策略权限永远是拒绝的

Audio对录音的影响测试（<a href="https://github.com/xiangyuecn/Recorder/issues/34">issues#34</a>）；IOS Safari如果未开始过录音并且播放了音乐，然后后续录音将会有问题；再现方法(<a href="https://xiangyuecn.github.io/Recorder/assets/ztest_apple_developer_forums_getusermedia.html">test apple developer forums</a>)：刷新页面后首先先播放音乐，然后开始测试录音，会发现波形显示掉帧或者保持直线。另测试浏览器对音频的支持情况。

注：录音时注意观察灰色区域是否有绿色音量跳动，没有绿色跳动说明Recorder没有获取到声音数据。如果测试发现mp3没有声音，可以试一下wav格式，如果wav格式有声音，说明内置lamejs mp3编码器有问题。如果都没有，下载下来播放看看有没有。下载下来也没有声音可以反馈一下。
