LIPA Hosts Theatre Sound Seminar By Out Board
For the second year running, Out Board's Dave Haydon and Robin Whittaker have given a seminar on Source-Oriented Reinforcement to degree students studying Sound Technology and Theatre and Performance Technology at The Liverpool Institute for Performing Arts, coordinated by lecturer Chris Layton and technical manager Andy Waddell.
Using a TiMax Audio Imaging delay matrix and multichannel speaker system set up in the college's prestigious Paul McCartney Auditorium, students were able to hear how control of relative arrival times between audio wavefronts 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 localisation 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, described as being "based on the theme of rhythm, the result of cross-collaboration between sound and movement".
