Record each coin once: one 10-second take, pinging it a few times. Add as many coins as you like, then send them together.
How to pingBalance the coin on a fingertip and tap its edge.
- Find a quiet room. Turn off fans, music and the TV.
- Balance the coin on a fingertip, flat and centered. Don’t pinch it or lay it on a table, or it won’t ring.
- Hold it close to the microphone, about 10–20 cm (4–8 in) away.
- Tap the edge gently with another coin or a pen. Let each ping ring out for a second or two before the next.
- Ping it 3 to 5 times. The take stops on its own after 10 seconds. Each coin gets one take.
In the 3D view, a good ping shows up as long, bright ridges: the coin’s resonant frequencies.
