   Then that should be the end of it.

   Actually, you did.

   There, you just did it again, whether you're aware of   
   it or not.

   Sure. Go down to your local radio shack. Buy a couple of   
   small signal diodes. Put 'em on the output of your player.   
      
   Or, unglue the surrounds of your speakers, misalign them and   
   reglue them.   
      
   Or, write a simple little program that simply resamples at   
   a higher rate with no filtering at all. It's real simple   
   to do. Or just take every sample and square it or take   
   its square root, or some other non-linear function.   
      
   All three methods will generate predictable high frequencies   
   where there were none before. All three are absolutely   
   garaunteed to do a half-ass job of it. Thus, all three   
   would meet what seems to be one of your most important   
   requirements.
