| Abstract | Analysis data are provided which are indicative of plural components making up an original sound waveform. The analysis data are analyzed to obtain a characteristic concerning a predetermined element, and then data indicative of the obtained characteristic is extracted as a sound or musical parameter. The characteristic corresponding to the extracted musical parameter is removed from the analysis data, and the original sound waveform is represented by a combination of the thus-modi?ed analysis data and the musical parameter. These data are stored in a memory. The user can variably control the musical parameter. A characteristic corresponding to the controlled musical parameter is added to the analysis data. In this manner, a sound waveform is synthesized on the basis of the analysis data to which the controlled characteristic has been added. In such a sound synthesis technique of the analysis type, it is allowed to apply free controls to various sound elements such as a formant and a vibrato. |
