Yeah, what I said... :)

I said:
"Normalization does not remove spikes, it simply brings the volume up
until the largest spike reaches the point just before clipping. All
levels remain relative to each other. "
Your quote said:

I said:
"I'm talking about taking an audio file and compressing it, evening out
the levels, preventing harsh spikes."
Now we just have to find a good Linux tool for this. :)
