This paper proposes a music signal synthesis scheme that is based on sinusoid modeling and sliding-window ESPRIT. Despite widely used audio coding standards, effectively synthesizing music using sinusoid models, more suitable for harmonic rich music signals, remains an open issue. In the proposed scheme, music signals are modeled by a sum of damped sinusoids in noise. A sliding window ESPRIT algorithm is applied. A continuity constraint is then imposed for tracking the time trajectories of sinusoids in music and for removing spurious spectral peaks in order to adapt to the changing number of sinusoid contents in dynamic music. Simulations have been performed to several music signals with a range of complexities, including music recorded from banjo, flute and music with mixed instruments. The results from listening and spectrograms have strongly indicated that the proposed method is very robust for music synthesis with good quality
