Still CD technology was developed to store only what the human ear can hear.
In order to save storage space, all low frequencies, the human ear cannot
hear were left out. Frequencies that you do feel, when they're being
reproduced, and that influence those that lie just above. Mini disc and DCC
work with storing only the dominant tones in a certain frequency range,
discarding a number of other tones in that range. Still nobody will have
noticed the difference, or say the sound is less 'emotional', this is what i
meant in the example, an uploaded human personality with a percentage of
loss, might be acceptable to some. The height of that percentage depends on
the individual value of both their personality, and the possible benefits
from such a technology.

hmmm, in the techno community i know many people who had nasal surgery, but
probably for different reasons...
