Hello Phil -

PM> article. 

Unfortunately the hardware available not long ago wasn't always
up to the task at hand and methods weren't as well developed as
they are now. Professional level sound recording is very much a
science now that I would put into the category of engineering
and not just a technician. 

To bring some of the old vinyl up to modern standards they
would have to add what was missed in the original. The results
would be a hybrid of the original plus new sound added to fill
in what was missed. Nothing wrong with that but at times I do
wish the original sound technicians had been sound engineers
with better hardware to work with. 

The recent use of psycho-accoustics to use harmonic distortion
to generate additional sound is really quite amazing. The THX
sounds of "Two Towers" in a good movie theater is just beyond
description. You believe that you are really _there_ within the
movie itself. Very nice.
