title: Sound clipping/clicking when lowering volume with NAudio
body: <p>Audio is clipping (or clicking) when trying to lower the volume of a WAV file in real time.</p>
  
  <p>I've tried it on a <code>SampleChannel</code>, <code>VolumeSampleProvider</code> and <code>WaveChannel32</code> instance, the source being a <em>32bit WAV file</em>.</p>
  
  <p>If I try it on a <code>WaveOut</code> instance, the clipping doesn't occur anymore, but I don't want that because it lowers the volume of all sounds in the application.</p>
  
  <p>And this only happens when I lower volume, rising it doesn't cause clipping.</p>
  
  <p>Is this a known problem or am I supposed to approach this differently?</p>
  
  <p><strong>Note:</strong> <em>this is how the volume drops in real time over the given time span:</em></p>
