Invisible triangle UFO? Sounds like a jet at first but lasts a minute

Anyway, a bit more to the story I only pulled out the camera and start recording when it’s felt like from the sound that it was pretty much overhead so I pulled out the camera. I was looking up when I pulled out the camera was like I’m gonna catch this, but there was nothing on the sound then kept getting louder as you can hear in the video and then it just kind of sticks around for 30 seconds or more and it literally sounded and felt like it was directly overhead. It was weird there was no wind I think what I can’t remember just this very strange sound. It was sort of sort of all around but. It was pretty weird.
