摘要：

This paper presents a novel solution for efficient representation of multi-channel spatial audio signals. Unlike other spatial audio coding techniques, the solution inherently requires no additional side information to recover the surround sound panorama from a two-channel downmix. For a typical five-channel case, only a stereo downmix signal is required for the decoder to reconstruct the full five-channel audio signal. In addition to the bandwidth saved by transmitting no side information, the technique has significant advantages in terms of computational complexity.
