Download A Robust Stochastic Approximation Method for Crosstalk Cancellation
Crosstalk cancellation serves as an important role in binaural signals playback through loudspeakers, which reproduce a particular auditory scene to the listener’s ears. In practice, due to either the listener’s head movement or rotation, etc, the actual transfer function matrix will differ from the design matrix, which results in deterioration in the performance of crosstalk cancellation. Crosstalk cancellation system (CCS) is very non-robust to these perturbations. Generally, in order to improve the robustness of CCS, several pairs of loudspeakers using a multi-band approach processing band-passed content to appropriately spaced loudspeakers are needed. In this paper, by means of assumed stochastic analysis, a stochastic robust approximation method based on random perturbation matrix modeling the variations of the transfer function matrix is introduced and evaluated. Under free-field condition, simulation results demonstrate the effectiveness of the proposed method.
