The audio commences with the faint jingling of keys. It gradually gets louder, signifying that someone is getting closer. The sound of a key being inserted into a lock follows, producing a crisp, metallic clicking sound. It is then turned, and the sudden release of the lock mechanism echoes with a satisfying clunk, indicating the opening of a secure cabinet. The subsequent creaking sound signifies the slow and careful swinging open of the heavy cabinet door. The audio concludes with the soft rustle of papers, suggesting that someone is leafing through the contents of the cabinet. The entire process captures the sequence of unlocking and opening a secure cabinet.
