Analysis of design parameters for crosstalk cancellation filters applied to different loudspeaker configurations

Several approaches to render binaural signals through loudspeakers have been proposed previously. Some studies had focused on the optimum loudspeaker arrangement while others had proposed efficient filters. However, to our knowledge, the identification of optimal parameters for inverse methods applied to different loudspeakers configurations has not yet been addressed systematically. In this paper, a study of three different inversion techniques under different conditions is presented. It is the purpose to obtain optimal filter parameters for the inversion techniques applied to different loudspeaker arrangements. Least square approximations in frequency and time domain are evaluated along with a crosstalk canceler based on minimum-phase approximation. Filter parameters, such as length and regularization, are varied and simulated for different span and elevation angles.
