A JOINTMINIMAX APPROACH FOR BINAURAL RENDERING OF AUDIO THROUGH LOUDSPEAKERS

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 immer-sive audio rendering filters having finite impulse responses for a sin-gle listener using loudspeakers. The work presented is applied to the traditional Atal-Schroeder crosstalk canceler structure. The min-imax 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.
