Frequently this can be caused by the belt idler pulley bearing and/or the tensioner bearing. Easy replacements from local auto parts store.

while its running, take a spray bottle with a little water and shoot at the belt. if noise goes away, its the belt. if not, then idler bearing, tenskoner.. or even alternator.
