<div><a href="https://github.com/xiangyuecn/Recorder/issues/51">issues#51</a>如果没有进行补偿，录音时设备偶尔出现很卡的情况下（CPU被其他程序大量占用），浏览器采集到的音频是断断续续的，导致10秒的录音可能就只返回了5秒的数据量，这个时候最终编码得到的音频时长明显变短，播放时的效果就像快放一样。未禁用时会在卡顿时自动补偿静默音频，消除了快放效果，但由于丢失的音频已被静默数据代替，听起来就是数据本身的断断续续的效果。在设备不卡时录音没有此问题。</div>

<button onclick="goiframe()">把页面放到IFrame里面测试权限请求</button>
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。

<span style="color:#f60;font-size:16px;font-weight:bold;">问题自检：</span>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。
