Noise from Front End of Motor?

[LameS4]

So, I pull in the driveway after work today and notice this terrible noise from my motor (my radio doesn't work so I never have music on and this is the first instance I've heard it). Sounds like something pulley related. Doesn't sound like it is with the accessory belt, which makes me nervous because I did timing, water pump and all that not even 10k ago, so I hope it's not something behind those covers.. Looking for outside opinions while I try to track it down.

Only thing in the front that sounds like pulleys are the pulleys.

You need a mechanics stethoscope.

Added a sound clip.

Hard to say. Use a long screwdriver to pinpoint where the nose is loudest. Take the serpbelt off to determine if that or whatever it's turning is the source of the noise.

Forgot I made this thread. It was the serpentine belt tensioner; in case anyone stumbles upon this thread down the road.
