title: Play 32 bit audio with NAudio and ASIO
body: <p>I try to play a 32 bit byte array via naudio and ASIO.
  But i can not get it running. The output signal is distorted.
  The same converting method works fine with 32 bit for naudio and WASAPI.</p>
  
  <p>Sample convert:</p>
  
  <pre><code>var newAmp = (int)Math.Round(amp * (Math.Pow(2, 32) / 2));
  var buffer = BitConverter.GetBytes(newAmp);   
  </code></pre>
  
  <p>The Play and record via naudio and ASIO:</p>
  
  <pre><code>var waveToneClass = new WaveTone(48000, 32, playBuffer, true, 1);
  var stream = new BlockAlignReductionStream(waveToneClass);
  
  asio_outin = new AsioOut(nameOfDriver);
  asio_outin.ChannelOffset = 0;               
  asio_outin.InputChannelOffset = 0;
  asio_outin.InitRecordAndPlayback(stream, 1, 48000);
  
  asio_outin.AudioAvailable += ASIO_dataAvailable;
  asio_outin.Play();
  </code></pre>
  
  <p>with:</p>
  
  <pre><code>private AsioOut asio_outin = null;
  </code></pre>
  
  <p>With 16 bit and the same method i get a clean Signal.
  But for very low output levels and a high gain i get artefacts and that´s the reason for 32bit.</p>
  
  <p>NAudio v1.7.3.0 / Windows 7 / .Net 4.0</p>
  
  <p>What is my failure?</p>
