Modifying tempo of musical signal is one of the basic signal processing for music signal, and many methods have been proposed so far. Nishino et al. proposed a tempo modification method of nonlinear modification based on sinusoidal model, but the evaluation of the methods was insufficient. In this paper, we evaluated the tempo modification methods with sinusoidal model and nonlinear signal stretch and compression. Namely, we compared effectiveness of use of residue signal and methods of determination of stretchable parts. From the experimental result, we could confirm the efficiency of the nonlinear tempo modification. We also compared several methods of determining the stretchable parts as well as the use of residue signal. As a result, the effect of the methods depended on the input signal.
