中文摘要：

多信源音频编码是指多个相关音频信源的独立编码和联合解码。它基于分布式信源编码定理,利用信道编码原理和信源之间的相关性实现信源的压缩编码,能在保证输出质量的基础上有效降低编码的复杂度。设计了一种非对称的多信源音频编码算法并进行了分析和仿真。结果表明：该算法编码简单且具有良好的性能。

英文摘要：

Multi-terminal sources audio coding refers to separate lossy encoding and joint decoding of two or more correlated audio sources. Based on distributed source coding, it compress source using the principle of channel coding and the correlations of sources. This coding can reduce the complexity and get good performanc. A asymmetry multi-terminal sources audio coding is designed and simulated. The encouraging simulation results show multiterminal sources audio coding is feasible, simple and can get higher acoustical effect.
