This listening event shows effects and music on a new quadraphonic surround-with-depth playback system, whose control, measurement, and design are described in our paper engineering brief at the convention. Our playback system consists of four loudspeaker cubes, each of which using four loudspeakers driven by a first-order beam control. We show how to involve reflections involved to create a stable sound image for a big audience, and how direct and first-order-reflected sound is used to get smooth surround panning (close sounds), while a set of second-order reflections permit panning to distant sounds. We will explain and play back the effects we programmed before listening to a mix of a surround-with-depth mixed song together.
