Squeal/Squeaking noise???

[rtstrack]

Just a few days ago a strange squealing/squeaking noise started coming from the passenger side of the engine bay (atleast thats the best that I can pinpoint it). It starts with a slow squeaking noise at idle and as you step on the gas it will speed up to a high pitched squealing noise. It's muffled by the sidepipes when you're moving along, but when you slow down its pretty annoying. A similar noise would be if you had low power steering fluid when you tried to make a turn or if you had wet brakes....if that makes sense. Any ideas? Thanks
