Single Channel Polyphonic Music Separation Using Sparseness and Overlapping NMF

Overlapping NMF와 Sparseness를 이용한 단일 채널 다성 음악의 음원 분리

In this paper we present a method of separating musical instrument sound sources from their monaural mixture, where we take the harmonic structure of music into account and use the sparseness and the overlapping NMF [1] to select representative spectral basis vectors which are used to reconstruct unmixed sound. A method of spectral basis selection is illustrated and experimental results with monaural mixture of voice/cello and trumpet/viola are shown to confirm the validity of our proposed method.
