The "Ball of Sound" is a high-tech 120-channel loudspeaker array with the size and shape of a soccer ball. This one-of-a-kind object was built by CNMAT researchers to explore the possibilities of controlling in real-time the directional properties of sound. We present interactive demos that move sound around using sensor inputs such as listener location, 3D pointing and virtual instruments.
