I think some software will perform XXX operations better than other 
soft/hard. I have experienced over the years what I have subjectively 
considered to be "bad Normalization" and "good Normalization).

>>>Not disagreeing here, I just don't have enough experience with other 
software to verify.  I personally use Wavelab 4 for all of my audio 
editing, and always have.  In "theory", normalization shouldn't involve 
any calculations that would affect audio quality (you're just tacking on 
extra bits), though certainly each manufacturer can have a different way 
of doing it. <<<

I am currently working with a Creamware SFP system and the Digital Gain 
that is available in the SFP mixer is great (imo) - but I guess what you 
are saying is that a more sure-fire QC method is Normalization, not 
Digital gain...and I can see the logic there.

>>>Pretty much hits it on the head.  I think there are vast differences in 
how various software companies calculate things like gain change, so 
certainly some manufacturers are better than others in this regard.  It's 
all about the processing resultion (is the signal path 24 bit, 32 float, 
64bit, etc), and more importantly, how do they deal with any calculation 
remainders.  Some companies used to just 'throw away' the extra bits 
post-calc, ouch! <<<

Which raises the question: In the E4 we do not have to think about this 
exact subject in the same way given the variable HEADROOM setting in the 
MASTER section (allows digital signal to be raised or lowered) - do you 
know how this type of operation figures into all that we have been 
discussing here?

>>>Without knowing how it's implemented, I can't say. I'm totally 
unfamiliar with the Emu sampler range too.  Again, 'in theory' anytime you 
change the gain digitally, you're affecting the quality of the audio.  But 
as I said in the last email, we're talking about VERY minor amounts of 
distortion.  Much lower than the noise floor of tape for instance. <<<
