Abstract(in English) | In this paper, we address a music signal separation problem with low-distortion structure method combining directional clustering and nonnegative matrix factorization (NMF). By combining directional clustering and NMF, we can extract the target signal from music signals consisting of many source mixtures. However, if we directly combine two methods, the estimated target signal suffers from much spectral distortion. Therefore, in this paper, we propose a new low-distortion-structured music signal separation method combining two methods. In the evaluation experiment, we estimate the target signals from the stereo music signals containing four music instrument signals. From the results, we reveal that the proposed low-distortion method is superior to other methods, namely, directional clustering, NMF and direct combination of directional clustering and NMF. |
