Corsair Whistling: Audio Bug or Intended?

[Invisibull]

I’ve raised this issue a few times since July 1 regarding the Corsair’s whistling sound effect, but I still haven’t seen any clarification or adjustment. Based on everything I’ve researched, the whistle should only be audible during high‑speed dives or aggressive maneuvers when the oil and/or intercooler flaps are at least partially open.

Right now in DCS, I’m still hearing the effect with flaps closed and at relatively modest speeds (around 190 knots). This is simply not how it should be and the fact that the sound file is encrypted means nothing can be done about it except by M3. 

So my question is simple:
Has M3 intentionally decided to model an incorrect implementation here, or is this still under review?

At the end of the day, we’re here to fly simulations that respect the aircraft’s historical characteristics. This particular implementation really undercuts that premise.

thx for your attention. 

Some sources: 

Robert "Bob" Brunson (VMF-312):
Brunson said:

"I never really noticed the whistle from inside the cockpit. But our ground crews would mention how it shrieked coming in low over the strip."
He added that the sound was more psychological warfare than something pilots relied on.

 

Lt. Col. Ken Walsh (VMF-124), Medal of Honor recipient:
Walsh confirmed that the Corsair made a noticeable whistle during dives, but emphasized that the pilot could not really hear it over the engine, particularly during combat or when wearing a flight helmet. He noted that ground crews and enemy troops were more aware of it than the pilots themselves.
