Authentic Reproduction of Stereo Sound - A Wiener Filter Approach
AES Convention 115 · Paper 5951 · October 2003
Abstract
Authentic binaural reproduction over loudspeakers using crosstalk cancellation is considered in this paper. A systematic time domain deconvolution method is presented using both stochastic and deterministic Wiener filters. This approach is advantageous over its frequency domain counterpart in that no additional stabilization process is required since the Wiener filter is inherently causal stable. A series of reproduction tests were conducted by changing the length of the Wiener filters in an anechoic chamber using a PC based reproduction system using a soundcard. Excellent performance was achieved with the filter length of only 500; less than 1% and 2% reproduction performance errors for the monaural and binaural reproduction tests, respectively.
