Static Radio Chatter: Plays random filter-modulated ground control clicks and static radio chatter during the fueling and countdown phases.Rattle Frequency Modulation: Adds high-frequency frequency modulation to the lowpass thruster noise to simulate structural rattle at ignition.Physical Distance Attenuation: Implemented a physical inverse-square law for the engine roar. Sound volume fades realistically as the rocket climbs away from the camera.
