So, when one does normalize I am wondering if it is better to
normalize a bit below 0.0? It seems to me that things sound a bit
better if the normalization is done to -1.0 or -2.0.
As I have said before, I seem to be getting pretty good results
with most of the audio that I do, but what I have learned is more
from years of experimenting rather than formal training. So, you
guys are a great help to guys like us.

You likely don't need to use dither, and SR doesn't support it
anyway.
If you are using a 16-bit sample size, you don't need to worry
about it.
If you are using a 24-bit sample size and you need to go to 16
bits, you
may have to worry about it some day. For a news clip, I wouldn't
think
of worrying about it.
Ideally, you would never normalize. If all recordings were
perfect,
that is, the signal just touching 0dB, you would never have to
normalize, and thus none of the problems with normalizing would
arise.
In trooth, many people, including myself, normalize. Purists will
tell
you that you are introducing noise from rounding, and all of this
is
true. But, it is so minimal, it really isn't a factor. What you
don't
want to do is continually play with the levels. For example, if you
need
to increase a signal by 12 dB, you wouldn't want to use the Change
Volume command 12 times, increasing by 1dB each time. Amateurs tend
to
do things like this, and it drives me crazy. Of course, even if you
do
something like this, you aren't likely to notice a difference.
In digital audio, it is always better to rank level changes the
following way:
1. Do nothing
2. Increase the level
3. Decrease the level
Decreasing is always worse, because it is the easiest way to
introduce
quantization noise. This is opposite the analog world, where we
are
always told that decreasing is better than increasing.

I am a reporter, not a big techie! Dither, shmither! So when do I
need to dither? I produce news stories, features and
documentaries. I'm a bit stumped on how to apply, or even to
apoply,
so much of the heavy tech stuff. Now, I know about EQ, of course,
and dynamic compression. I try to stay away from normalizing as
much
as possible. I find it sqeezes the sound and creates a certain
sameness--I don't know all the technical terms here. When is it
advisable to use normalizing? My main engineer discourages its
use.
