Doppler effect of a glass ring dropping on a table

The audio begins with the sharp, clear sound of a glass ring being released, followed by the high pitched whine as it descends onto the table. As it makes contact, the sound changes; it's a sort of clinking noise, like the chime of a tiny bell. The Doppler effect is noticeable as the pitch of the sound shifts, representing the change in frequency due to the movement of the source. The glass ring then starts to roll across the smooth surface of the table, producing a series of quick, rhythmic taps. The Doppler effect comes into play once more, as the pitch of these sounds fluctuates as the ring moves. Gradually, the rolling slows down, each tap becoming more distinct and drawn out. The Doppler effect is less pronounced, but still present. The audio concludes as the ring finally comes to a stop, leaving behind a brief echo and a lingering sense of motion.
