title: OpenAL Sound direction
body: <p>I have a question about OpenAL. I wrote a class which optimizes work with OpenAL. I mean it provides convenient functions for work. StackOverflow, my question is about direction of sound.</p>
  
  <p>When I rotate the source of sound around the listener, the sound at the bottom or top positions disappears, it is not audible. I think that at the top and the bottom point the sound should be just more quiet. I think that the sound is not directed at the listener. What should I do to make the sound be always directed at the listener when I change the position of the source in space?</p>
  
  <p>change position <code>al.alSource3f(source[0], AL.AL_POSITION, x, y, z);</code></p>
