Addendum on aerial layer: Beyond the global HPF/RT60 adjustment, the jet/rotor distant hum layer itself needs dedicated attention — its falloff slope at 300m+ is currently too steep, and the 80–250Hz low-mid engine bodythat gave BF3/BF4 that "rolling thunder from the sky" feel is effectively muted by aggressive HPF. Recommend: dedicated distant jet/rotor hum layer with relaxed falloff + extended RT60 + simulated ground coupling, so that a fighter 500m out still carries that oppressive low-frequency rumble across the map. This is what made BF3/BF4 skies feel alive.
