title: AForge Fourier transform
body: <p>How to use this method:</p>
  
  <pre><code>public static void DFT (Complex[] data, Direction direction)
  </code></pre>
  
  <p>if my input array is <code>short[] samples</code>? I can easly convert <code>short</code> to <code>double</code> to put this value to <code>Complex</code> struct. But this struct has two field <code>Im</code> and <code>Re</code>. So, one of these values will be my sample value right? What is the second value? Sample number?</p>
  
  <p>Please help me to solve this problem, because I will not sleep today.</p>
