Begin in Idle Mode and then Switch Off

As the audio begins, one can perceive the calm hum of an engine in idle mode. The soothing rhythm of an automobile motor, gently purring and idling. It's the sound of a vehicle at rest, but readily available to start. This is the sound of an auto engine in its dormant state, just before ignition. Suddenly, the listener is aware of a change. With a twist of the ignition, the serene hum of the idling engine begins to fade. The familiar, comforting drone of the motor is replaced by silence. The vehicle, once ready and waiting, shifts to being shut off. The abruptness of the switch-off is palpable, leaving the listener with the stark realization of the absence of the engine's sound. The once vibrant motor in the automobile has now transitioned to its inactive state. You are left with the quiet that follows, the silence echoing the vehicle's transition from start to shut off.
