The audio begins with the distinct sound of a hard object being manipulated, reminiscent of the sturdy shell of a walnut. It's clear, crisp, and slightly unsettling. This is followed by a sudden, sharp crack, echoing the sound one might associate with a bone breaking. The intensity of the sound suggests a significant amount of force being applied. Despite the jarring nature of the audio, there's a certain rhythmic quality to it, creating an ebb and flow between anticipation and the release of tension. The stark contrast between the initial manipulation and the final cracking sound leaves a lasting impression, eerily mirroring the process of cracking open a walnut or, in a more macabre sense, a bone.
