    • PROBLEM TO BE SOLVED: To provide a device capable of extracting a beat of rhythm of music with high accuracy, while reproducing music signals of a musical piece, and capable of following up the reproduced music signal, even if there is fluctuations in the extracted beat. SOLUTION: There is provided a beat extracting means which detects a portion where the power spectrum in the spectrum program of the input music signal changes by a large amount and outputs a beat component extraction output signal that is synchronized in time with the changing portion. The autocorrelation of the beat component output detection signal is detected, and the tempo value of the input music signal is inferred. The oscillation central frequency of a variable frequency oscillator is determined by the inferred tempo value. The oscillation output signal of the variable frequency oscillator and the beat component output detection signal are phase-compared, and the phase of the oscillation output of the variable frequency oscillator is controlled by the error signal compared. A beat synchronizing signal, synchronized with the input music signal, is generated from the oscillation output of the variable frequency oscillator and is output. COPYRIGHT: (C)2007,JPO&INPIT
