title: Convert wav to wma
body: <p>I want to convert a .wav file to .wma (or .mp3) on Windows Phone 7 Mango.</p>
  
  <p>I want to save a recording from the microphone and use the SaveRingtoneTask so I can save it as a ringtone. </p>
  
  <p>How can I convert the file on Windows Phone 7 so I don't have to use a web service? </p>
  
  <p>If it can't be done on the phone does anyone know how to convert it and trim it down to 40 seconds? </p>
