Weird sound across my town ?

After spending an hour or two in the woods with some of my friends, we went home. Shortly after arriving home, we heard this strange sound. Note that we don't live together, we all live in a range of 2-5 km apart (5 friends). At first I thought it was a car alarm and I didn't worry about it.

Shortly after me and my friends went on discord and we mentioned the strange sound. Someone from my friends snapchat managed to capture the sound. What could this be ?
