title: Visualization of MP3 - PHP
body: <p>I'm trying to build an mp3 player for my site using JavaScript (and any plugins/frameworks(jQuery)/libraries that are relevant) &amp; html5. So I built the player (more accurately, I implemented jPlayer), and now I want to make a visualizer.</p>
  <p><em>Ok maybe it's not a visualizer (all the names for ways to visualize sound always confused me), I guess what I want is something like this (Update: I just found out this is called a <a href="https://www.google.com/search?q=waveform&amp;gws_rd=ssl" rel="noreferrer">waveform</a>):</em></p>

  <p><em>Or just something that graphs the amplitude (loudness) of an MP3.</em></p>
  <p>I've been told I <a href="https://stackoverflow.com/questions/6638552/get-relative-loudness-of-song-javascript/6638786#6638786">can't do that with javascript</a>.</p>
  <p><strong>So does anyone know how to do it with php?</strong></p>
  <p>More accurately, does anyone know how to graph the loudness/amplitude of an MP3 using PHP? I know that once I get the loudness I can make a graph using GD or the Google graphs image API.</p>
  <p>Any API's, ideas, frameworks will all be much appreciated!</p>
