I did a thing as a kid that basically proves it out.
I recorded my home, an afternoon with the family from the speakers that it would be played back from. After some fiddling with a pre amp to get the recording balanced well enough to play back, the effect was pretty effective.
I didn't expect it, but when that recording was played on that system and speakers, it was possible to sit in my room and basically hear the house! TV in the front room, dog walking around, doors closing.
Brought people in late at night to play it. Was spooky to hear midday sounds, and believe them. The illusion was that good.
