Cross-talk cancellation and dual-channel audio equalization technique for audio applciations

摘要

Three dimensional (3-D)sound effects depend on psychoacoustic spectral and phase cues being present in a reprodced 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 presentsan innovative dual-stage algorithm that greatly improvesperformance in the presence of highly correlated inputs.HTis first stage uses a modified dual-channel direct path modeling algorithm to model to path netowkr form 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.
