This just made it into slashdot.  They also seem to not know
what is going on, but maybe some of the feedback will
enlighten us.

My guess is that they take the mp3, decode it, and then
add noise to the spectrum above 16khz.  The level of the
noise is taken from interpolating (actually, extrapolating
in this case) the data below 16khz.  (is that what you
mean by an audio exciter?)

Sounds like snake oil to me.  But maybe adding some low
level noise actually sounds better than having silence
above 16khz?
