The audio begins with the subtle, rhythmic sound of human fingers tapping lightly against a surface, hinting at a sense of nervousness or anticipation. Then, there's a brief pause. What follows is the distinctive, crisp sound of fingernails being bitten. It's a sharp, quick sound, almost like a click or snap but with a more organic quality. The chewing sounds are intermittent, each bite taken with a certain deliberation that creates a strangely hypnotic rhythm. There are slight variations in the sound, indicating different nail lengths and thicknesses. The audio ends with a soft sigh, a human exhale that seems to suggest a temporary relief from the nervous habit.
