Yes very technical, not a clue what you just said :)  Thanks for that 
though Aaron, I never realized normalization involved a multiplication 
process, points to Ed.

Not quite.  Normalization involves a multiply by a non-integral number
which leads to error, albeit down below the level of the original bit
depth.  For example, pretend you have a 2 bit system (4 levels).  If
you normalize a signal of 1,2,1,2 you'd have to multiply by 1.5,
leaving you with 1.5,3,1.5,3 which truncates to 1,3,1,3 or rounds to
2,3,2,3.  Either are wrong to the tune of up to a single bit.  While a
single bit is significant in a 2 bit system, it is negligible in a 16
or 20 or 24 bit system.

Wow, that was technical...
