OverUnder by Antti Pussinen is an analog synthesizer based sound sculpture, that creates infrasonic sound waves around approximately 16Hz. Over tones of base frequency are created by folding original waveform into itself.
Since most of the frequencies in the artwork are below hearing range (and below the range of my recorder), a sense of pressure is missing from the video. The low frequencies one can hear are a product of sound reflections inside the gallery room.
Analog sound synthesis based sound works are like sculptures. In a sound synthesis circuit, electricity is forced to form abstract waveforms in electric current. A speaker transforms these electric waveforms into waves in air
pressure. Since no data is lost in digital to analog and analog to digital conversions, a viewer can feel and hear the original sculpted waveform in full detail.
The power of digital revolution is based on evaluating what is relevant information, and filtering out the rest (for example outside of hearing range in digital audio). With this development we are maybe losing some feeling or content that is seen irrelevant, but is still there.
