The system of three-dimensional sound which is expanding not only in the horizontal plane but also fills the space above and under the listener, thus creating an audio sphere. The term and the format were invented by Professor Gerson from Oxford in the early 1970s.

Unfortunately, as all genial inventions, it was ahead of time and due to absence of appropriate technical facilities was undeservingly forgotten.

Interest in the ambisonic format has been growing recently.

Objects or light sculptures that produce sounds. Sometimes sound becomes an art object by itself. This kind of art evolved from kinetism, and it is followed mostly by composers and video artists. Often these objects are linked to the environment, and they are site-specific (made to fit into a certain place or landscape).
