A weird sound from the front left corner(maybe)
 

A weird sound started suddenly yesterday on our 4.4i (2001). My wife, who is very clever to find the weird noises on a car(I really mean it, she's good), drove it a day before and it was ok, no weird sounds.
Here's the video about the sound:

On the video 0:28--> and 1:20--> are the best moments to hear the sound.
It's not coming from the engine because the rev's don't have any effect.
It does vary with car's speed. Turning doesn't affect it. The front wheels spin normally, no additional brake friction or sound.
So, what could it be: the wheel bearing, the inner CV joint, something else??
I have spend two evenings under the car and tried to find the origin of the sound...

The answer was the left front wheel bearing.
