AB  - A new algorithm of converting two-channel audio materials to five-channel based on subband unsupervised adaptive filtering is proposed in this paper. This algorithm uses a subband analysis-processing-synthesis framework. In each subband, a robust stereo image is obtained using principle component analysis, and an effective energy re-distribution among surround channels is achieved by mapping cross-correlation between two input channels to a weighted panning matrix.
