摘要

Using the wave field synthesis (WFS) method, the sound of primary source was reproduced by plane waves. Although having some shortcomings such as spatial aliasing, these plane waves enlarged the sweet spot of the listening area and decreased the localization error of the sound source. Also, we suggested a grouped reflections algorithm (GRA) for reproducing early reflections. This sequence of early reflections increased the spaciousness of the listening room environment. The result, obtained by applying this method, was implementedbylineararraysof32loudspeakersconstructedinananechoicroom. Forbackwardcompatibility with standard five channel surround titles, a new hybrid sound field processing algorithm using WFS and GRA method was implemented.
