Sorry, *that* message was to scare off the easily impressed :-) I'll describe
more carefully from here on.

Closer to it, anyway.  Of course, this *still* depends on the amount of real
entropy in the signal, but most of the perceived entropy in a signal encoded
using an LPC coefficient+residual scheme is simply due to a poor fit (a
consequence of the nature of the filter).

Actually, cymbals produce strong and weak peaks in a pattern that mostly appear
random.  They're still a worst case, but LPC could be doing better than it is
doing :-)

What remains to be seen is if what I want to do is even possible.  I'll also
answer the previous mail that asks specific questions I'm sure you'd also like
answered...
