It's mostly one of the pulleys. Maybe just an idler pulley. Take off the belt and start the car and see if the sound goes away. If it does then you know it is a belt driven component. You can use a mechanics stethoscope or long screwdriver to put against objects to pin point the source. Just place your ear to the handle and listen.
