I always understood that the unique "shrieking" sound of the older Dauphines/Gazelles was due to the main rotor interacting with the fenestron but this one loses the main rotor and it's still "shrieking". Also, listen to that fenestron whine initially go really high after it loses the load of the main rotor!
I think the "shrieking" does not come from the fenestron, more likely from the engines. Check the video from the AS350 crash at Auckland Harbour some time ago, same noise.
