soundwave,
is it a whining sort of noise? does it change in tone when revs build from idle - ~2500ish?
I have a problem like this and I think its the bearing for one of the pulleys thats going bad. Possibly the idler pulley or tensioner that will need to be replaced.
It used to happen on and off and I thought it was my alternator but when I used a multimeter to check it, it seems fine and I think its coming from a dying bearing.
It's getting especially annoying now so I may be replacing the bearing/entire pulley soon!
