Subject:another normalization question
Posted by: Tempest

OK, so I recorded some DJ sets onto MD. The MD, when simple
recorded to WAV through my sound card in really quiet. The
peaks on the source file are about -3.5dB.

I tried normalizing using SF to -6.0dB which someone had
mentioned is what commerical CD's are mastered to.

Of course, this seems to have made everything a hair
quieter, exactly what I didn't want. My undestanding is
that normalizing applies gain to lower the peak levels to
whatever you set as the max.

I should mention that the peaks in the source aren't
particularly louder when listened through speakers, so I'm
not sure why they're there.

Anyway, what's the best way to increase the perceived
loudness of my recording?

Hi Jay,

Try normalizing to -0.5 dB, that should do more of what you wanted,
but if you're interested in pushing up the 'perceived' volume, you
may want to look into www.sonictimeworks.com Mastering Compressor
plug-in. I used it recently with SF 4.5 on an Theatre Organ concert
recording, and it sounded great. You could also experiment with the
Dynamics processing (compression) that is on the Forge menu.

Another method that you might try in order to increase the perceived
loudness of your sound file is to use the RMS Normalizing function.
Do a Scan levels on the file, set the "if clipping occurs" box
to "Apply dynamic compression", then click the Average (RMS) option
button and set the fader to a level a little higher than your scanned
value.

By the way, every major label CD that I have ever digitally loaded
into my DAW has come in with peak levels at 0.0 dB (or VERY close to
that) which tells me that the big boys master their CDs to zero.
Makes sense since everyone wants their CD to be as hot or hotter than
the rest.

Hi JR,

I believe I was the one that posted something about CDs being
normalized to -6dB. I guess I should have elaborated on that more.

Actually, CDs are constantly being mastered hotter and hotter. The
latest prince CD I got (Joy Unto the Rave Fantastic) has a Peak of
0dB and an RMS of -2dB or -3dB!!!! As technology gets better, the
levels get hotter!!!

I would like to clarify this, EVERYONE PLEASE READ...

There are two types of normalization in SF, Peak and average RMS.
When I refered to the -6dB, that was in Reference to the average RMS
level of the recording, NOT the peak level of the recording...

THE PEAK LEVEL OF YOUR RECORDING SHOULD ALWAYS BE 0.0dB!!!!!!!!!

That said, you can have a file with a Peak of 0.0dB but a RMS of -
20dB!!!!! The Average RMS is the average volume over time.

Try this....

Open your DJ mixes you want to normalize in SF. Go to Process Menu |
Normalize.

In this window you will see a few things..

First, change the "Normalize Using:" To "Average RMS power".

Second, click the "Scan Levels" button in the lower left corner of
the window. Let it do it's thing (this will take a little while)

Third, Write down the Peak and RMS number it gives you (should
display the numbers right below the "Scan Levels" button).

You now know what your project's levels are at. Since you are
recording DJs and most DJs use samples, you may not really need to
normalize that much because most samples are normalized to begin
with...and since the DJs are spinning other peoples songs, those
songs they are spinning are most likely normalized as well...so when
working with DJs you are usually going to have an easier time
Normalizing levels....anyway...moving on.... :-)

now that you know what your peak and average RMS are...you can now
accurately normalize using RMS. you said that when you used a
setting of -6dB it got quieter. There are two obvious reasons for
this...

One, you didn't change the "Normalize Using:" to "Average RMS power".

Or

Two, your file already has an anverage RMS that is higher than -6dB.

since you are working with a recording from a DJ either one is very
possible...

Now going back to those numbers you wrote down a few minutes
ago...the Peak and RMS values of the file. If your peak is -3.5 and
your RMS is say -4dB...then you really don't need to Normalize using
RMS!!! But if your peak is -3.5dB and your RMS is say -12dB. You
may want to normalize it.

Basically...When you Normalize using average RMS it is similar to
Compressing the file...in fact most professionally mastered CDs use
compressor/limiters to "Normalize" the recordings. For Example I
know that some mastering studios use Wave's L1 plugin (www.waves.com)
for Normalizing.

The one thing you have to remember is.................. You
normalize to get all of the recordings going on to the CD at the same
volume. You don't want track one to be very loud and then track two
to be 15dB quieter!!! So if your average RMS is -6dB or -20dB, just
as long as all the songs going onto the CD you are making are that
same level you shouldn't have a problem.

One other thing I would like to add....Sonic Foundry's effects and
plugins are great!!!!...but sometimes 3rd party plugins are what you
need to get the sound you want.

I use Wave's Renaissance Compressor/Limiter to Normalize all of my
recordings. It is not that I think the Sound Forge Compressor and
Normalizer are inferior, I do use them. But, Every time you do
something to a recording it is going to "color" the recording. I
like the way the RCL (short for Renaissance Compressor/Limiter)
sounds and what it does to my recordings, that's why I use it.

Hope this helps. Sorry for the confusion!

GREAT EXPLANATION, O.G. Killa

but there is just one thing you forgot to explain:
is that Normalizing in peak mode is nice, because you can get the
maximum bit accuracy, but if you are using RMS, in fact you can
destroy your favourite recording, because you are compresing the
audio contents instead optimizing up to the last (but not least) bit.

In other words, pay attention at what are you doing... with your
EARS !!!. Listen first,... and then apply just the minimum process in
order to get right in front of the massive attach of HIPERMAXIMIZED-
AND-OVEREQUALIZED-PLUS-PERFECTLEVELED-AND-JUST-SUPEREXCITED-AUDIO

Sorry at all, but I'm annoyed, because I't seams that where we are
going is to a perfect 192Khz samplig rate........ at 2 bits !!!!

Please let the music have DYNAMIC AND EXPRESION AND LIFE !!!

Hermes

Hi Hermes, Thanks for the heads up...I have another post on here (the
one in which I originally mentioned -6dB RMS Level) that talks more
about using the Peak Normalization Feature.

But really, my post was to help this particular person with his
particular problem...I was not posting a "Technical Note on
Normalization", it was more directed specifically towards RMS
normalizing techniques. In a previous post I had explained the
difference between Peak normalizing and RMS normalizing. When this
person I was replied to attempted to try and normalize his recording
he wasn't exactly in the right spot. He followed my suggestions but
he was following my suggestions for RMS while he was using Peak in
SF. He never Switched to RMS in the Normalize window, so the result
was not what I had described. Hence, it did not have the affect he
desired.

I hear what your saying about dynamics and I agree with you. But
fact of the matter is, to the untrained ear, the louder the song is
the better the perceived sound is.

There is a great interview with Bob Ludwig about mastering on Parsons
Audio's website (http://www.paudio.com/Pages/learning_Ludwig.html)
and he talks about this.

Being a musician I love dynamics, I love the excitment cresendos and
diminuendos create. But, since I work for other people and not
myself, I have to do what they request. Most of the music today is
highly compressed, drastically EQ'd, and drenched in effects. Just
because I don't agree with it doesn't mean I shouldn't know how to do
it nor should I deny someone else that knowledge.

So, I appologize for not mentioning Peak normalization in this post.
And I would like to reiterate to anyone who has not learned about
peak normalization to do so.

Thanks.
