title: iOS Audio Trimming
body: <p>I searched a lot and couldn't find anything relevant... I am working on iOS audio files and here is what I want to do...</p>
  
  <ol>
  <li>Record Audio and Save Clip (Checked, I did this using <code>AVAudioRecorder</code>)</li>
  <li>Change the pitch (Checked, Did this using Dirac)</li>
  <li>Trimming :(</li>
  </ol>
  
  <p>I have two markers i.e. starting &amp; ending offset and using this info I want to trim recorded file and want to save it back. I don't want to use "seek" because later on I want to play all recorded files in sync (just like flash movie clips in timeline) and then finally I want to export as one audio file.</p>
