The noise at the end of your recording is the wakes vortex as it descends to ground level. Wake vortexes (or vorticies) are spiral cones trailing behind each wing and are a by-product of lift. They eventually disipate but the aircraft was low enough, and you close enough, to experience them. They can be hazardous to following aircraft so sometimes a minimum separation is imposed.
