Took this audio recording while walking my dogs near a river valley in Central Illinois. The noise I'm not sure about is like a low whooshing sound. Kind of like someone spinning a jump rope really fast through the air.

If I had to guess the noise was on the other side of a 500ft clearing in a tree line. The Merlin app wasn't able to identify it as a bird of any sort and I have no idea what sort of mammal would make this noise in the midwest. It's not like any bobcat, fox, or coyote call I've ever encountered and I cant imagine it was something smaller than that still.

White tailed Deer can make a similar noise when frightened they exhale aggressively through their nose, either to alert other deer of danger or to scare away what ever scared them im not quite sure.

That's it! I had no clue that white tailed deer made this noise and I've lived here for 30 years!

Yeah, it's not a sound most people hear. It's a bit more common for hikers and hunters to hear it, especially later in the evening.
