send audio file to a client and save it in it's device
<p>I am working on node.js project , I am stuck in sending file from client to a  client and save it at device  receiver  , as same as whatsapp sending recording file from client to client .  </p>

<h2>I try to send file by routing :</h2>

<pre><code>app.get('/music.mp3', function (req, res) {
    ms.pipe(req, res, "music.mp3");
});
</code></pre>

<p>but when the browser(client) receives  the file , it  starts  to play it .</p>
