Abstract
In the waveform processing apparatus of the present invention, an original sound signal is divided into a plurality of bands, parameters such as amplitude and frequency are extracted for each band, and correction is made so that the amount of deviation of the parameters from the mean value thereof is gradually decreased to zero from a certain time to the time when the repetition period begins, whereby a musical tone signal is re-synthesized based on the corrected parameters. The electronic musical instrument which stores the waveforms processed by the apparatus of the present invention generates musical tones having more natural tone color change.
