The AC compressor clutch pulley would not be my first guess but maybe. I’d first suspect a tensioner or idler pulley. With a $10 mechanic stethoscope and extension from HF, you might be able to pinpoint it. If your car is old or high mileage, you might want to replace them all and the belt. Some replace the tensioner assemblies as well but I don’t think they go bad as soon as the pulleys. If you pull the fan and remove the belt you maybe able to spin the pulleys and hear a more gravelly ticking from one with a worn bearing but it is a bit of work to do that just for a test and you might want to replace them all and the belt at the same time.
