Efficient architecture for spatial hearing expansion

Abstract

A new efficient method for a two channel source 3-D sound system is presented. This architecture provides an efficient surround effect with two speaker systems while maintaining the front components of the original source. This method uses the head related transfer function (HRTF) for new sound localization which provides listener perception of spatial hearing expansion. Unlike the conventional 3-D algorithms which require heavy computation, the proposed method produces natural 3-D sound with a small amount of computation. Also, this method maintains the channel separation. This characteristic proves another advantage over other 3-D sound algorithms.
