sound, 3D sandstone print
sound: 2' 58" / print: 12" x 2"
This video presents a 3D sandstone print of sound - an aural sculpture inspired by the Meridional Overturning Circulation (MOC) aqueous kinetic sculpture. This is what I was hearing as I watched the slow, silent flow of cold, salty deep water under warm, fresh surface water (espresso) over several days in the 1.52m glass tubing.
The horizontal stratification exhibited in the print is comprised of frequencies - more lines at any location along the length equate to more frequencies in the sound. The timeline of the work reflects the distant relationship between extremes of stratification and the mixing and diffusion over time, with complex timbres evolving from the interplay of oceanic realms.
I used a synthesizer to create sound layers, a band-pass filter to dynamically control the frequencies of the sound layers, and then a Fast-Fourier Transform (aka "spectrograph") to visualize the frequencies in the sound. A image file of the frequency visualization was converted to a color 3D object via a 3D terrain-mapping algorithm, and then printed in sandstone.
