摘要: A method of processing a single channel audio signal to provide an source having left and right channels corresponding sound at given direction in space, includes performing binaural synthesis introducing time delay between the inter-aural difference for coming from said direction, controlling ear magnitude be respective values. These values are determined by choosing position relative head listener use, calculating distance chosen ears listener, determining using inverse square law dependence intensity with cues perception use.
