Hum/whine at highway speeds

Recently seemingly sudden noise starts of hum/whine loudest above 70mph proportional to groundspeed, independent of engine speed. Attached are sound clips. Any ideas?

It is obvious that one of the 5 (FWD) or 7 (SHAWD) bearings is making noise. You need to lift the car, turn off the traction(VSA), accelerate to 70 miles per hour and listen to each of the bearings with a stethoscope.
