is concerned with 3-D audio systems implemented using a pair of conventional loudspeakers. A well-known problem with these systems is the requirement that the listener be properly positioned for the 3-D illusion to function correctly. This book proposes using the tracked position of the listener's head to optimize the acoustical presentation, thus producing a much more realistic illusion over a larger listening area than existing loudspeaker 3-D audio systems. Head-tracking can be accomplished by applying pattern recognition techniques to images obtained from a video camera. Thus, an immersive audio environment can be created without donning headphones or other equipment.
discusses the theory, implementation, and testing of a head-tracked loudspeaker 3-D audio system. Crosstalk cancellers that can be steered to the location of a tracked listener are described. The objective performance of these systems has been evaluated using simulations and acoustical measurements made at the ears of human subjects. Many sound localization experiments were also conducted; the results show that head-tracking both significantly improves localization when the listener is displaced from the ideal listening location, and also enables dynamic localization cues. Much of the theory and experimental results presented are also applicable to loudspeaker 3-D audio systems in general, not just head-tracked ones.
is of interest to researchers studying virtual acoustic displays, and to engineers developing the same. The book serves as a valuable reference to anyone working in this field.
