Abstract :
We integrate with Dynamic Matrix System (DMS) to develop the system that multi-channel audio signals can be converted by a two-channel stereo audio signal, in addition, the number of channels is adjustable. A spatial decomposition method of mixture sounds based on the spatial localization is used in this system, which can separate multi-sounds by estimating the spatial location of the sound source. Then, the separated audio contents and azimuth information will be resynthesized and reconstructed by DMS systems. Furthermore, the sense of reality and immersive on reconstructed sound stage will be promoted.
