   Of course you *can* add extrapolated information with harmonic synthesis,   
   whether it sounds "better" will be purely subjective of course. It's common   
   to do the same thing at the other end using sub-harmonic synthesis too.

   That also fails to realise that proper interpolation WILL make the picture   
   look far smoother, and edge detail can be enhanced as well while your at it.   
   All in all the picture WILL look better to most people, even if no REAL   
   detail has been added. Same thing with audio.   
      
   What you can't do is make a silk purse from a sows ear, or do what the TV   
   forensics shows would have you believe is possible :-)
