I agree with Dejablue. Sounds like a loose pulley on a tensioner. I am guessing it is eithe the Compressor or power steering. You can also completely remove every single belt, and see if the sound is still there. Don't drive like this obviously. Also, did you tigten down the crankshaft pulley with an impact? You kinda gotsta. Tightening it by hand without a torque wrench means that it is only kinda tight.
