Abstract :
This paper presents a multi-channel audio coding method compatible with the standard stereo audio coding method. The encoding method consists of three parts: spatial-temporal analysis of sound source location, compressing multi-channel audio into stereo audio and encoding stereo signals. The proposed method is simpler and more effective than conventional methods in terms of audio data size with small additional information. With proposed method, it is possible to transmit or store multi-channel audio signals as stereo audio signals.
