我已经附上了示例代码。只是我需要知道如何将音频文件保存到驱动器Ex- D：// RecordedAudios //。
我附上了我完成的全部代码。
我想要实现的是，当我单击“停止”时，它将把我的音频保存到给定的驱动器中，因为我想创建一个表格来记录用户的音频，然后单击“停止”它保存到我的项目或特定的驱动器中，以便稍后我曾经把它取回来。

<h1>Simple Recorder.js demo</h1>
<p>
Matt Diamond‘s <a href="https://github.com/mattdiamond/Recorderjs">Recorder.js</a> is a popular JavaScript library for recording audio in the browser as uncompressed pcm audio in .wav containers. Before it the only way to record audio was to use Flash.
