Jerobeam Fenderson - Nuclear Black Noise (oscilloscope / lissajous music)

7“ Vinyl: This track is part of Nuclear White Noise • Nuclear Black Noise, a composition for continuous or discrete frequency spectra. AUDIO In this part only sine waves (discrete frequencies) were used. Using the harmonic series, i.e. integral multiples of the fundamental frequency, an unlimited variety of sound spectra can be created (additive synthesis). To produce these waveforms the open-source audio programming software Pure Data was used. VIDEO What you see is what you hear. Left/right channels cause vertical/horizontal deflection on an oscilloscope, which was filmed for this video clip. Each frequency's phasing differs between both channels, so that the waveforms look different on each, whereby complex interference patterns and shapes can be created (lissajous figures). licence: Creative Commons BY-NC-SA
