title: Channel Audio from .mp4?
body: <p>I am at a loss here after searching around with no results.</p>
  
  <p>I am attempting to channel the audio specifically from an .mp4 for use in a driver.</p>
  
  <p>I am aware that there are programs which extract the audio from .mp4's, but I am looking for another approach without using external applications such as those.. is there any direction that someone can point me towards to solve this problem?</p>
  
  <p>Thanks,</p>
  
  <p>-K</p>
