Renault mods whining noise from under the bonnet, increases with revs, sounds lick a pulsing diode, could it be the alternator, although no warning dash lights and shows no sign of low battery?

I have had the alternator bearings checked out and ok, with the belt removed the noise stops. Belt drives alternator & air conditioning drive motor. Although the belt tensioner pulley spins ok without noise, going to try a new one? Any comments
