AB  - In order to save the transmission bandwidth of surround sound, a technique named Hierarchical Bandwidth Limitation (HBL) was proposed by the authors. In HBL, a psychoacoustically hierarchical transform is used as the preprocessing algorithm prior to bandwidth limitation. In our former experiments we found that the Karhunen-L¨°eve transform (KLT) is a suitable hierarchical transform for HBL. Besides the hierarchical transform, the choice of an appropriate strategy for bandwidth allocation is also essential from the point of view of the resultant audio quality. In order to find the optimal bandwidth allocation strategy that achieves the best audio quality, the authors attempted to build up the mathematical relationship between audio quality and the bandwidth allocation strategy using a MUSHRA listening test. The experiment design and results are reported in this paper.
