Default Normalize....lowers volume and more!?

This is really messed up! I don't know what's happening:

When I normalize the item, the volume drops! But wait, that's not all...when I run an analysis, it shows that the normalizing HAS raised the volume and yet, trust me, not only does the Item's Peak display clearly not show that but what comes through my speakers is definitely lower in volume as well!?

I can't imagine I'm doing something wrong here...this is a bug, right?
(It displays really small in the forum so it might be better to view full screen here:

Looks normal...
You start with a file with peak of +5.57 dBFS and it gets normalized to -0.01 dBFS....

You're missing the point. That's why this thing is messed up. Clearly the SWS action reports the volume has been raised but as I explained, it hasn't it...it's reduced it!

Just look at the change in the item's peak sizes when I run the Normalize action, there's a big drop, it shrinks!
And that is also very audibly reflected through the speakers, no doubt, the volume has gone down and not up despite what the SWS is reporting.
I could post a video with audio but that shouldn't be necessary, trust me and as I said, just look at the gif, the peaks don't lie!

Take a good look at the peak value before you normalize the file...it is a positive number...ie...over 0 dBFS.
Of course it has to lower the gain to normalize to 0...

Oh?...crap. Sorry, I feel like an idiot. I didn't realize Normalize worked both ways, i.e. not only raising the volume but also lowering it.

I had just never experienced that before. Virtually every file I normalized always resulted in a either a visible & audible increase in volume or it appeared to do nothing which is when I assumed the peak level of normalizing had already been reached in the item and that therefore not normalizing was applied.
In normalizing 100s of files, I never saw a level drop before.

Well, I learned something today and sorry for wasting a minute of your time!

(it's a shame one can't delete a thread. I've posted already so many useless ones like this one)

it's funny how our logic is based on our experience...i used to think the same thing...
makes sense to think normalize is positive gain to "0" (or "max")...but with floating point, there really isn't a "max", so it will normalize to "0" (ie..."1" or "-1").
glad to waste my time here with my fellow idiots

Haha!
Next time, I'll be able to spread my wisdom for the future idiot to come.
Cheers,
