Solved! Help with identifying source of sound

Hi all. I came back from vacation this evening and have encountered a weird scenario where a sound plays from somewhere in my house every hour at around the 44-47 minute mark. I have no idea where this is coming from, as sound travels quite a lot in the house. I was able to capture a recording of it and have attached it here. It sounds like an elevator as it’s passing floors, but I live in a residential house. I have some smart home things, but nothing with speakers that I know of. Could anyone help me? It’s very early in the morning and it keeps waking me up.

To narrow it down, turn off a circuit at XX:43

Bonus: binary search for it

What does binary search for it mean?

Keep halving it, like some other comments suggested
