There are lots of possibilities, and those two are on the list.

If you can record a short video or audio clip of the noise for us to listen to, that would be much more useful in zeroing in on the culprit from long distance line this.

Take the belt off and start it. Is the noise gone? If yes shut it off and spin all the pulleys by hand. Any noises or looseness? Put the belt on and start it. Take a piece of wooden broom handle and put one end on the alternato, water pump, etc and your ear to the other end. Figured out my bad alternator bearing this way.
