I assume the noise is present whether the car is in gear or is moving. If that's correct then the bearing on the idler pulley for the AC belt is the most likely culprit, but it could also be an alternator bearing. The bearing in the AC compressor is the least likely insofar as it's pretty beefy.
If you get an automotive stethoscope, you'll be able to narrow it down pretty quickly. Otherwise, pull off the AC belt and see if the noise goes away. If it does, give the idler pulley a spin. If it's not smooth, you've found the source.
All of the bearings can be replaced without having to replace the entire component.
