High pitched whirring noise when accelerating?

I hear a high pitched, almost whispery whirring noice when I accelerate. It seems to happen intermittently, more often on wet roads but perhaps that’s just coincidental? It only happens when I accelerate and goes away when I coast/brake, and tends to happen more often at higher speeds. This started about a week ago. It doesn’t seem to change pitch or go away if I turn my wheels.

I can’t quite catch the noise on a video, but it almost exactly sounds like someone making a noise halfway between blowing out and whistling.

I do not know very much about cars at all, so any advice before I take it to a mechanic would be helpful! Happy to provide more info as well.
