title: basic wav data chunk
body: <p>I have a question about the basic wav file data chunk.</p>
  
  <p>I know that each 2 bytes in the data chunk section represent mono sound and left and right channel is alternately stored, but I still have no idea how to understand the 2 byte value.</p>
  
  <p>Is it high and low?</p>
  
  <ul>
  <li>value 0000 => lowest? </li>
  <li>value FFFF => highest? </li>
  <li>value 8FFF => no sound?</li>
  </ul>
  
  <p>If so, when I want to reduce volume 50%, is all I have to do just classfy low and high 
  and divive by 2?</p>
