Here's a question maybe someone out there can answer:
Why isn't it possible to completely restore a recording: for example, to remove
all extraneous noise (hiss, clicks, coughs), even to make a reasonable guess
about information not in the original recording (for example, given a score
and a knowledge of the harmonics of a voice or an instrument, to recreate
something close to the sound of the original performance)?
