What\'s that whine noise I hear right after landing a airliner?

I was watching some airliner cockpit videos and I noticed right after landing I heard some sort of mechanical whine, not sure if it was the autopilot disenguage warning sound or the auto throtles moving or what. Anyone know? This was in a Boeing of some discription. I noticed it more than once.

Short wine about 2 sec? Probably the movement of the speedbrake handle as it automatically moved aft after touchdown.
