[78-L] Removing hiss - yet another idea

Interesting concept, but surely syncing the 2 sides up would present a 
problem, as we have discussed here many times whenever the subject of 
accidental stereo comes up. OTOH, maybe using a digitally controlled 
table would provide speed uniform enough to do this? Proper centering to 
  an *extremely* narrow tolerance would be a prereq, I would think, as 
the tiniest amount of wow would cause a pitch shift, maybe too small to 
hear but large enough to confuse your computer doing the comparison.
