diff between "Gain" and "Normalize" in Audiosuite

[natives]

Can anyone tell me the differences between the 2?

Here's how I see it:

With Normalize, you're limited to the highest audio peak. The plugin will bring all audio levels up, relative to the highest peak. Once the peak hits the "ceiling", the plugin won't go any further.

With Gain, it looks like it will just keep boosting levels until, in practice, you could have one big fat waveform. By that time, most everyting would be unintelligble, of course.

So, Gain is Absolute, while Nornalize is Relative?

Gain looks like it's more flexible, since you can lower levels, as well as raise them.

What am I missing here?

Thanks
