Non suspension squeak.

apologies if this isn't the right spot. I am new here.

I have a squeak that sounds exactly how you'd expect a suspenssion squeak to sound except it is rotational sounding with the speed of the engine. It gets quieter and faster as the engine speeds up then gets louder and slower as it slows and only while in gear and while it's actually moving. It doesn't seem to do it if I give it a small shot of gas while the hand brake is on or if it's in neutral either still or rolling. It sounds like a squeak not a whine. Any thoughts you could share will be appreciated.

 

My first thing to check would be the serpentine belt and pulleys
