I don't think this would sound Clackity Clack, but since it's so simple to check out it's worth the try: Do the fanblades on the alternator by any chance hit anything? When the RPM on these go up they tend to bend out a bit becuase of the centrufigal forces. If they do, they'll make noise and eat through your fanbelt if you're unlucky enough...
