title: How to remove vocal from a sound track prefereably mp3
body: <p>Did anyone ever tried or worked on an app that removes vocal data from the mp3 file leaving the midi/the background music track.</p>
  
  <p>Is there any open source lib for that to accomplish and how far this is attainable.</p>
  
  <p>Appreciate the ideas if any.</p>
  
  <p>Thanks In Advance</p>
