Ephemerospheres is an installation of electroacoustic audio works for wave field synthesis speaker array. Combining several of my compositions with those of guest composers Linda Gale Aubry and Seth Cluett, Ephemerospheres creates a shifting audio ecology that adapts itself to the room and its occupants in the welcoming quiet of Nolan Park.
Why Wave Field Synthesis? I designed and built my wave field synthesis (WFS) speaker array as part of Ears In Space, an umbrella project that includes my work in spatial audio technology and environmental recording. Wave field synthesis places virtual sound sources in real space with a high degree of precision, using dozens of small speakers in a linear array. A computer coordinates the firing of the loudspeakers to generate coherent wave fields in a two-dimensional space in front of the array. While much larger arrays exist at institutions such as EMPAC in Troy, NY - where I was first inspired to work with this technology - the Ears In Space WFS array is designed for intimate spaces, smaller galleries, and homes. The system is modular and fits into a large rolling suitcase, allowing for expansion and experimentation.
Ears In Space Field Recording Kit Print on card stock, free to all visitors
The Field Recording Kit was designed to give visitors something to take home with them to keep thinking about ephemeral listening environments. Though it isn't necessary to use one to experience Ephemerospheres or any wave field synthesis, there's never a wrong time to use the Ears In Space Field Recording Kit.
