You are hear the clutch less transmissions shifting. The race cars use a setup different then the street version of the PDK, which has nothing to dampen driveline sounds during shifting, resulting in loud noises when shifting. If you watch the FIA rally cars, which also use racing clutch less transmissions, you will hear a similar sound when they shift.
