The audio starts with the distinct sound of a faucet being turned on. Soon, a steady stream of water can be heard flowing out. This is followed by the clear, crisp sound of water filling up a glass. It starts as a soft trickle, then gradually grows louder as the glass fills up. The water's flow is unbroken and continuous, creating a soothing, rhythmic, and somewhat musical sound. The echo of the water in the glass subtly suggests the glass is being filled on a hard surface, maybe a kitchen countertop. Finally, the sound of the faucet being turned off indicates the end of the filling process. The last few droplets of water dripping into the glass mark the conclusion of the audio piece titled "Water in a Glass".
