title: How to export the left and right channels of a very large wave/audio file (400meg/22+mins) as an image
body: <p>How to export the left and right channels of a very large wave/audio file (400meg/22+mins) as an image (the best format maybe a vector image format) See wave file image below. I'm trying to superimpose the Left and right channels on top of each other to get a graphic.    </p>
  
  <p>I know I can do a screenshot but there's no way to get a 22+min sound file zoomed in to fit on one screen.  Is there a way to export each  channel zoomed in as vector art?</p>
