A Linear Robust Binaural Sound Reproduction System with Optimal Source Distribution Strategy

Crosstalk cancellation system plays an important role in binaural sound playback using loudspeakers and has attracted many researchers' interest. However, limited sweet spot is still a challenge especially when the head is laterally misaligned. In this report the optimization of a linear binaural playback system is proposed, in which the optimal source distribution strategy in a linear array configuration is combined with the technique of multiple control points. The proposed method aims to find a good trade-off between the crosstalk cancellation performance and the robustness against the head misalignment. Both simulations and experiments demonstrate the efficacy of the proposed method.
