     Will alow you to add any sound to your level! You can make
     sounds play randomly, loop, be static, or full volume through the

   "attn" -1, 1, 2 or 3. specifies the annotation of the ambient sound.
     -1 is played full volume over the whole level (ATTN_NONE), 1 is for

     3 is the default.
