Javascript make audio blob
<p>I am testing the html audio tag and I would like to <strong>make audio blob url's</strong>, like youtube or vimeo does, and add it to the <strong>"src"</strong> to start playing the audio.</p>

<p>I've been testing with <code>new Blob()</code> and <code>URL.createObjectURL()</code> but I don't know how to use it.</p>

<p>I would like to do something like:
<code>&lt;audio controls src"blob:null/8142a612-29ad-4220-af08-9a31c55ed078"&gt;&lt;/audio&gt;</code></p>

<p>I would greatly appreciate your help.</p>
