摘要: An integrated spatial audio system based on subband filtering and a panel speaker array is developed in this paper. This system is intended for a personal computer and is capable of rendering sound images positioned arbitrarily around a listener, synchronizing with the video image. The proposed system features the spatial audio technologies such as the head-related transfer function (HRTF), the reverberator, and the cross-talk cancellation system (CCS). Of particular importance in this paper is that inverse filtering with Tikhonov regularization technique is employed in designing the multi-channel filters to cancel the crosstalks. To ease the computation loading, the CCS is implemented for frequencies below 5.5 kHz by using a subband filtering approach. The system is implemented on a 5 x I panel speaker array. Experimental investigation indicated that the proposed system is effective in creating an immersive sound field, in complement with video rendering. (c) 2005 Elsevier Ltd. All rights reserved.
