This paper describes a method for jointly designing the crosstalk cancellation filters to facilitate binaural rendering of audio through loudspeakers. The minimax criterion is used to design the immersive audio rendering filters having finite impulse responses for a single listener using loudspeakers. The work presented is applied to the traditional Atal-Schroeder crosstalk canceler structure. The minimax approach provides improved low frequency performance and a better overall separation of the direct path and cross path transfer functions than the conventional least-squares designs.

This paper presents a method for jointly designing immersive audio rendering filters for a single listener using loudspeakers. The filters for crosstalk cancellation are assumed to have finite impulse responses and are designed using the minimax criterion. In addition to the traditional Atal-Schroeder crosstalk canceler structure, this paper explores an alternate topology that requires the approximation of a single filter. In general, the minimax approach provides improved low-frequency performance leading to a better overall separation of the direct-path and cross-path transfer functions than least-squares designs. The performance of the single-filter structure is better than that of the traditional crosstalk cancellation structure.

This paper presents a novel approach for implementing immersive audio rendering filters for a single listener using loudspeakers. We address the problem of crosstalk cancellation inherent in loudspeaker rendering and propose to implement the crosstalk cancellation filters using minimax finite impulse response (FIR) filters. The formulation is based on the Atal-Schroeder crosstalk canceller. The use of the optimal FIR filter design procedure ensures significant amount of separation between the direct path and the cross path. An alternative topology which requires the approximation of just one filter has also been explored using the same design principles. The minimax techniques provides superior solutions as compared to a least-squares design and the alternate structure is shown to be robust in its performance.
