title: Draw an image as a waveform?
body: <p>I want to export a series of images (a movie) and draw as a waveform, like how:</p>
  
  <p><a href="https://www.youtube.com/watch?v=M9xMuPWAZW8&amp;feature=youtu.be&amp;t=328" rel="nofollow noreferrer">https://www.youtube.com/watch?v=M9xMuPWAZW8&amp;feature=youtu.be&amp;t=328</a> did</p>
  
  <p><a href="http://oscilloscopemusic.com/" rel="nofollow noreferrer">http://oscilloscopemusic.com/</a> offers a program for loading 3D <code>.obj</code> files but I am currently working in 2D.</p>
  
  <p>I tried opening a .WAV downloaded from <a href="http://www.wavtones.com/functiongenerator.php" rel="nofollow noreferrer">http://www.wavtones.com/functiongenerator.php</a> in vim and my terminal program crashed.</p>
  
  <p>I tried <code>.cat Downloads/wavTones.com.unregistred.sin_1000Hz_-6dBFS_3s.wav | pbcopy</code> and pasting into a text editor which showed <code>RIFFæ</code>.</p>
  
  <p>What is an algorithm for converting a series of images into a .wav? Ideally I'd like to make many images and string them together to make a movie like Oscilloscope Music does.</p>
  
  <p>The Aphex Twin is using more than 2 colors and I'm not sure what's going on there.</p>
