title: Split audio files using silence detection
body: <p>I've more than 200 MP3 files and I need to split each one of them by using silence detection. I tried Audacity and WavePad but they do not have batch processes and it's very slow to make them one by one.</p>
  
  <p>The scenario is as follows:</p>
  
  <ul>
  <li>split track whereas silence 2 seconds or more</li>
  <li>then add 0.5 s at the start and the end of these tracks and save them as .mp3</li>
  <li>BitRate 192 stereo </li>
  <li>normalize volume to be sure that all files are the same volume and quality</li>
  </ul>
  
  <p>I tried FFmpeg but no success.</p>
