Try this. Turn all electrical components off and start it. Then turn all electrical components on to see if the sound changes.
It certainly can be a bearing failure as you mentioned, but it sounds to me like it's coming from the alternator, but I am listening to a recording.
You may also want to remove the belt and spin each component to see if any make noise or have excessive play.
Let me know. Also, let me know what I can do to help you.
