title: WebAudio API: Change pitch of samples (for example mp3)
body: <p>I figured I can stretch a sample using <code>playbackRate</code> but how do I set the pitch? Im trying to achieve this without using any libraries.</p>
  
  <p>I found something about a doppler pitch effect in the specification but other than that I couldnt find anything truly relevant to my objective. Just a simple pitch shift, is this even possible? If so then how?</p>
  
  <p><strong>Edit</strong>: Could it be that <code>playbackRate</code> changes the pitch as well but the browser applies some sort of correction? I think this might be the case. I have to disable it then if that is the case and possible.</p>
