In the audio titled "086640_Shutting Off Power", you hear an amalgamation of distinct sound effects. It commences with the humming of a power source, a constant and resonating sound that fills the space. This is a blend of real-world foley and synthesized sounds, creating an immersive soundscape. Gradually, the humming intensifies, signifying the build-up of power. Then, there is the sound of a switch, a definite, metallic click, signifying the action of shutting off. This is followed by a sharp, sudden decrease in the humming sound, depicting the power shutting off. The sound fades, transitioning from a powerful, almost overwhelming drone, to silence, leaving an echo of its presence. Finally, the audio concludes with the faint electrical crackling, like the dying embers of a fire. The soundscape created is both realistic and synthetic, taking the listener on a journey from an intense power operation to the calmness of its absence.
