ICASSP 2006 Proceedings. 2006 IEEE International Conference on 5 V-V 1-4244-0469-X musical_structure A method for segmenting musical audio with a hierarchical timbre model is introduced. New evidence is presented to show that music segmentation can be recast as clustering of timbre features, and a new clustering algorithm is described. A prototype thumbnail-generating application is described and evaluated. Experimental results are given, including comparison of machine and human segmentations http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=1661200
