collaborative sound installation created with Philip White


AVPFE is a complex electronically generated feedback system with autonomous behavior. The user influences this system in an acoustic environment revolving around spatial manipulation of sound through parabolic reflectors. Each of the four reflectors has at its focal point a microphone or a speaker enclosure. As the visitor explores the space he or she interrupts the flow of sound waves, causing further changes in the feedback cycle. Sound from the microphones is then translated into video through the addition of a carrier signal. AVPFE gives rise to many psycho-acoustic and visual phenomena and draws a direct link between the two. The viewer’s attention is focused through the melding of the aural and the visual so that one can discern even the most minute of fluctuations in his or her perceptual environment. Furthermore, the slightest movement can alter this environment, calling attention to the way in which our actions connect to what we see, hear and experience.
