Cross-talk cancellation makes the reproduction of binaural audio possible through loudspeakers. This is typically achieved by employing a digital signal processing network that controls the acoustic pressure at the listener’s ears. Although this can be achieved by using only two loudspeakers, there has been a recent tendency of using loudspeaker arrays, which increase the robustness to source errors and reduce room’s response influence. This document presents a numerical study on the trade-off between cross-talk cancellation performance and the number of channels of a loudspeaker array. Special attention is given to the conditioning of the array and how this is affected by inaccuracies in the driver response for different numbers of loudspeakers: 2, 3, 4, 5, and 7.
