Abstract

Transaural rendering allows for the reproduction of binaural audio material without the need of wearing headphones. This is achieved by the use of cross talk cancellation systems, which are generally implemented with stereo loudspeaker pairs. The robustness and quality of the crosstalk cancellation depends on the frequency of the reproduced sound and on the source span of the stereo set up. As this limits the frequency bandwidth where effective crosstalk cancellation can be achieved, nested stereo systems with different source spans have been proposed as a method to enhance the bandwidth of the crosstalk cancellation. This technique is compared in this paper to a linear loudspeaker array of 16 uniformly sources used as a crosstalk cancellation system. The performance of the uniform array is first compared to that of a nested stereo array by means of off-line simulations. The robustness of the crosstalk cancellation is analysed with respect to room reflections and reverberation. This effect is also studied by investigating the total acoustic energy produced by the linear array, in comparison with that produced by the nested stereo array
