could be the bearings in one of the pulleys. maybe try spinning the differant pulleys and checking for wobble/tightness? hard to tell, but you sound certain it is in the serpentine system? (ie, it sounds like a squeeling belt)

Could the intake be whistling? Maybe it's an injector? Something in the distributor? Could it be something in the valvetrain (just guessing there). Otherwise x2 on bad bearing somewhere. Maybe a mechanic's stethoscope would help track it down, I got one for $5 at HF and I love it.

crawl up under it and verify the harmonic balancer is not rubbing on the timing cover. They are known to breakdown and begin to separate at the rubber ring and that'll allow the outter ring to walk backwards toward the timing cover.

X2 on the harmonic balancer. When mine went bad it sounded just like a squealing belt.
