Got a show that is 100 mins. When I try to normalize in Wavelab I get an error that the new file is gonna be over 2GB. How can I get around this so I can normalize the 100 minutes together rather than having to split it up and then normalize each section.

I know Sound forge will do It..but then again I never normalize so I'm not the best to ask.

cool edit pro will do it too. the only solution I have been able to find is to split it. :-\
-
or lower your editing bits to 16-bit editing
i know in default in wavelab 5.0, its set at 32-bit float editing

Lost my copies of CEP and SF last time I reinstalled XP.

it is a small hassle to put a marker halfway through the wav file, and normalize two sections, but that is what i do, and it beats going back to soundforge or cool edit pro any day of the week...

More work and more time, but this should work....
File > New > Wave
Select your Audio Properties
Ok
Edit > Insert Audio File
Select your audio file
Normailize
Save

This is how I handle my 24bit stuff too.
Edit: I'm using WaveLab 5.0 btw.

Can you be sure the result is the same as normalizing the entire file as a whole?
-
ahhh, good point. so i never actually use the normalize command. what i do is analyze the whole file. Then when I boost, i use the MECompressor plug in to boost at exaclty what is needed to get it to -0.3 dB. (I use the MECompresser because it has the cleanest fucking boost IMHO, I dont actually do any sort of compression).

The result will not be the same. There will most likely be different amounts of boost applied to each section (unless the peak level in each part is exactly the same, which is highly unlikely).
This will give you an audible change in volume at the spot where you rejoin the two files.

Why normalize?
Signal and noise will go up.
Nothing that plain old analog gain can't do.
The only thing here I see as worth doing is a little compression/limiting so dynamics are easier to handle at home.
Yes, then you still have the noise issue (if your original SNR was not high enough) but at least you get somethign back.

Why normalize?
You clearly don't have a multiple disc changer and children. :laugh:

True...
But just normalizing is not worth it as I described above. If you do want to change (perceievd) volume etc do some slight compression/limiting.
-
yeah - I use L2 for limiting and dithering.

either split the wav into 2 mono wav's and normalize, or cut the stereo file in half. If you cut the stereo file in half, check the peak level on the first half and then normalize. calculate the diference between the origial level and the normalized level and use the "leveler" plugin to boost the 2nd half by the same amount. If you split to mono you may want to verify there are no 1-sided spikes that would throw off the normalzing or do the "check peak > norm > leveler" thing for the mono wavs.

Another way of doing this: some s/w will calculate the gain required to bring up the entire recording to 0dB (or some user-defined threshold). So do this with the complete WAV file. Then, after splitting the stereo WAV in half, simply apply the same amount of gain - as calculated above - to both files.
