ESPectre
Motion theremin
Connect a device and turn movement into sound, or try the instrument in demo mode.
Turn movement into sound
The theremin turns the movement score into pitch: more movement, higher note; a still room is silent. Connect an ESPectre device, or use simulated motion in demo mode.
Sound starts only when you press start. Choose a sine, triangle, or sawtooth wave; no microphone is needed.
