When binaural audio signals containing directional cues are presented with loudspeakers, the listener should still be able to localize sound images and experience a realistic three-dimensional sound environment. Because acoustic crosstalk between loudspeaker channels degrades performance, it is necessary to preprocess the binaural signals with a crosstalk cancellation system. However, a limited sweet spot is still a challenge especially when the head is laterally misaligned. To increase the robustness of the reproduction system, a direct multidrive array configuration with multiple control points is combined into the optimal source distribution strategy. The research goal is to find a good trade-off between the crosstalk cancellation performance and a high tolerance to head misalignment. Both simulations and experiments demonstrate the efficacy of the method, and the system is well suited to large display devices.
