Abstract:
1. A system for generating audio signals, comprising: a surround mapping unit configured to receive input audio signals having surround sound information contained therein from a plurality of audio channels and generate, via a nonlinear surround mapping scheme, a pair of output stereo-channel audio signals based on the input audio signals, where the pair of output stereo-channel audio signals are embedded with surround sound information, including binaural cues and sound spatial image information; and a stereo-channel encoder configured to encode the pair of output stereo-channel audio signals generated by the surround mapping unit to produce a pair of encoded stereo-channel audio signals with the surround sound information, including binaural cues and sound spatial image information, wherein the pair of encoded stereo-channel audio signals with the surround sound information is transmitted to a stereo-channel decoder via one channel, and the surround sound information included in the pair of encoded stereo-channel audio signals is capable of being used by the stereo-channel decoder to generate surround sound effect.
