I guess I didn't ask my question very well.

What does 0VU really mean?  I assume it is power related but I'm not sure of
all the nuances.....and I suspect that there is a temporal dimension to it.
Otherwise why would Nackamichi make such a big deal about their peak VU
meters?  Are VU's constant across frequencies?

So, what is 0 VU really mean?  I want to know so that I can consistently 
normalize my speech signals.  The energy in a digital impulse train is very
different from a full-scale sine wave.  Speech is somewhere in between.  Just
how high can I crank the analog gain before I saturate the tape with random
speech data?

Thanks.
