Fireworks sound weird now

I had a video ask of "explosive fireworks", so I take the video, and it's fireworks exploding in the camera, so I could see the flash fill the room. The sound was NOTHING like I've ever heard a firework before. It was kinda like a quick, sharp, echo portion of "I will not be silenced" "I will not be silenced" "I will not be silenced" on repeat. Every once and awhile it would jump to what sounded like, "I'm not the one being silenced, I'm not the one being silenced" "I will not be silenced" "I will not be silenced". It made a firework sound at the end of each explosion, but for some reason, it was something that was treated like a backing track, so it wasn't prominent. I think there are a lot of sounds that aren't really real in the simulation.
