Is the sound all artificial or recorded elsewhere and mixed in? After Mach 1 you shouldn't really be able to hear any engine noise...

Artificial, I think.

Not neccessarily. You just need a medium that the sound waves can trave through. The rocket body itself can be that medium.
Remember those film-scenes from Wild-West-Movies where they put their ear on the (railroad-)tracks?
Nevertheless, I can not definitely say whether the sound is 'artificial' or not. We need reliable sources! Until than, it's just guessing.

I concur. Note the racket that starts up as the transonic condensation clouds form, and then cuts out very suddenly.

See the note in the lower left corner at 0:07.

Jepp, right. I think (educated guess) that this is more or less logical.
First the microphone picks up the noise via the air. This is what most microphones are designed for
After the air density gets thinner and thinner[1], the microphone starts to pick up most of audio wave signals via direct vibrations through the mounting.
I would compare it with e.g. scratching on your notebook while using the build-in microphone. It [the mic.] will still 'hear' the scratches although the sound is very different (kind of low pass filtered).

Didn't notice that the first time, thanks for the hint

[1] ...and/or the noise-source gets trans/super-sonic...

I found an awesome handheld camera video from inside Endeavour during STS-134 of the payload bay doors opening.

Ah, good old STS-125.
