Abstract :
Three dimensional (3-D) sound effects depend on psychoacoustic spectral and phase cues being present in a reproduced signal. Dual-channel audio equalization and cross-talk cancellation allow accurate phase and spectral cues to be reproduced over dual-channel loudspeaker systems. This paper presents an innovative dual-stage algorithm that greatly improves the performance in the presence of highly correlated inputs. The first stage uses a modified dual-channel direct path modeling algorithm to model the path network from the loudspeakers to the ears. The second stage uses the direct path model to form the inverse filter network to compensate for the effects of these physical paths
