Using a TiMax Audio Imaging delay matrix and multi-channel speaker system set up in the college's Paul McCartney Auditorium, students were able to hear how control of relative arrival times between audio wave fronts affects accuracy of panoramic and surround imaging, essential in theatre and live presentation to maintain authenticity and intelligibility. The demonstrations included the delay-time boundaries that create undesirable comb-filtering and echo-perception, and how combining delay localization with conventional level panning can significantly enhance the perception of multi-channel surround sound effects over a wide audience area.
Out Board subsequently loaned a TiMax ImageMaker8 system to LIPA, at the request of students Dan Bennett and Colyn Lewin, to help implement their animated sound design for a dance, sound and installation production called Chimaera, a production based on the theme of rhythm and the result of cross-collaboration between sound and movement.
