Vibration of a Plate or Ruler on a Table

The audio begins with the soft thud of a flat object, presumably a plate or ruler, being placed on a hard surface, such as a table. There's a brief silence before the sound of a hand swipe is heard, causing the object to vibrate. The sound it produces is a low-frequency hum, almost like a gentle buzz. Suddenly, a sharp, high-pitched ping reverberates, signifying a strike at the edge of the plate or ruler. The object continues to vibrate, the frequency steadily increasing. The sounds become more rapid, the pitch rising as the vibrations intensify. The rhythm is like a fast-paced heartbeat, a testament to the energy transferred from the swipe to the object. The vibrations eventually slow, the frequency decreasing until it eventually comes to a stop. The audio ends with the fading echo of the last vibration, leaving behind a silent table and a stationary plate or ruler.
