Okay - I've now listened to the shorter one three times.
The initial sound sounds like something dragging, like a loose chain against the ground.
Then the sound changes to a definite rotational sound.
You need to determine if it is related to engine speed or wheel speed.
If engine look to the accessory belt and pulleys.
If wheel look to the hub, rotor or CV joint.
I don't think it's rotor, as this usually sounds like a circular saw cutting steel.
it could be a brake pad wear sensor against a rust ridge. This typically sounds like a bird chirping.
