In order to find optimum trade-offs between high data rate and high perceptual quality in multichannel audio transmission, a hierarchical bandwidth limitation algorithm for multichannel audio was proposed by the authors. In this paper, subjective effects of bandwidth limitation based on two hierarchical transform techniques were studied with formal listening tests. The first technique used Gerzon’s MSBTF transform and the second method used a Karhunen-Lòeve transform (KLT). The results were compared and discussed.
