Detailed Description

Sound source interface (implemented in sound driver dynamic library)

• If the buffer is mono, the source is played in 3D mode. For arguments as 3D vectors, use the NeL vector coordinate system:

  
   *     (top)
   *       z    
   *       |  y (front)
   *       | /
   *       -----x (right)
   * 

• If the buffer is stereo, the source is played in stereo mode.
