I just can’t wrap my head around it. Is it just crazy brain things, a difference in number of waves, or some other thing? How is it possible that a speaker can replicate all sounds?

Im not sure this is what you are looking for, but basically, your brain makes it up. At some point in evolution, there was an advantage gained if your brain created a different sensation to differentiate two different vibrations in air. I dont think scientists know how your brain does this, but we do know how the data gets to the brain: there are structures in your ear (a hammer and a drum if your are five 🙂 that cause different electrical impulses to travel in a nerve when different vibrations are experienced.
