Buzzing sound at low RPM?s
 

I am trying to pinpoint the source of this buzzing sound. It seems to be related to engine rpm (and not vehicle speed). It is noticeable at 2-3k rpms and goes away when I push the clutch in and the engine returns to idle. It seems like it?s coming from up under the dash where the clutch and transmission are. I?ve attached a link to a video below. Does anyone know what this sound could be? The car is new to me, so I suppose it could be a normal sound as well.
