he was able to explain, using the audio engineering concept of
noise-shaping, how it is that we hear sound so well, to such a "fidelity"
that using silicon-based systems (44100*16 bits per second in one ear),
through this known neural bottleneck of our auditory nervous system.

i'm getting there.  there was a lot of stuff suddenly plopped onto comp.dsp.
i haven't caught up with the entire thing posted nor with the existing
thread from wherever this came from.

still pretty busy.  expect sporadic response.
