What you’re hearing is pre-ignition, which occurs when there’s a pocket of fuel/air mixture that’s igniting ahead of the flame front from the spark plug. When this happens, there’s a tiny shockwave that occurs around that explosion (along with the normal detonation from the spark plug), which greatly increases the pressure in the cylinder.
