title: Using FFmpeg or wrapper to get mp3 from mp4 in C#
body: <p>I'm trying to extract an mp3 from a flash compatible mp4 file and have so far found FFMpeg and a bunch of different wrappers that all claim to be able to do the job.</p>
  
  <p>Ideally, I'd like to not have to rely on shelling to the FFMpeg exe, but none of the wrappers I've tried seem to work....</p>
  
  <p>Has anyone got any code or advice for how to go about this?</p>
  
  <p>Thanks!</p>
