PURPOSE:To provide a sound source device capable of accurately reproducing an attack part. CONSTITUTION:In analysis frames AF1-AFn, the Fourier analysis of respective source waveforms is performed and representative frequency components are extracted on condition that the frequency components of a large level are selected and the phase, amplitude and frequency of the respective frequency components are detected in the analysis frame AF1 and the frequency components in harmonic relation are selected and the amplitude and the frequency are detected in the analysis frames AF2-AFn. In the case of reproducing the source waveforms, sine waves provided with the frequency, the amplitude and the phase obtained in the analysis frame AF1 are generated and synthesized in a synthesis frame F1 and the sine waves provided with the frequency and the amplitude obtained in the respective analysis frames AF2-AFn are generated and synthesized in resynthesis frames F2-Fn. |
