8 x 8 Ω / 1 bit: Live Electromagnetic Induction Audio Process, a new work by artist Arcangelo Constantini:

8 independent microcontrollers generate an oscillating square pulse that is emitted as current and voltage to a coil, that create a variable electromagnetic field. four induction coils capture the invisible field that is amplified once again in to electromagnetic waves sent to speakers, which use electromagnetic induction to convert the electrical current back into sound. spinning the platform and controlling the independent necks, attack sustain release and decay could be achieved
