Giant Spectrum is an interactive audio-visual piece that displays a live, moving spectral representation of the sounds it hears. Much like light, sound is comprised of many different frequencies, and different sounds contain changing frequencies with varying amplitudes. As sounds occur, the piece shows these changing parts in real time as a moving spectral display. Any sound present in the room appears on the display. Giant Spectrum was constructed over a four month period from December 2015 to March 2016, and is made of aluminum, polycarbonate, and custom electronics.
