title: Cutting a clip from iPod library file
body: <p>My requirements are as follows:</p>
  
  <p>I need to access a song from iPod library and play it(which is doable). I have implemented this using Assets library, and now I need to trim that song programmatically, so that I can get a clip of it. One application is already on the app store featuring same functionality, called "Ringtone Designer" Any thoughts?</p>
