Abstract
Abstract A waveform of a desired sound is displayed on a CRT, and is observed for the analysis of the waveform. Waveform information including a shape, a repetition number, an amplitude, and a frequency of a segmental waveform which is a part of the displayed waveform is supplied to a repetitive PCM data generating unit, by which the repetitive PCM data are generated. The repetitive PCM data are developed to be a PCM sound signal which is converted to an analog output sound signal. A sound generated by the analog output sound signal is appreciated.
