title: Remove background noise from a WAV file in iPhone
body: <p>I have a recorded WAV file. I want to remove the background noise and separate the speech alone. Is there any C/C++ code available for achieving that, so I can integrate in my project?</p>
  
  <p>I have downloaded a code from Audacity but unable to integrate it. Is there is any third party library or C/C++ code available?</p>
