Waveform reproducing apparatus has waveform reproducing unit that generates output waveform data which is temporally compressed or expanded version of original waveform data

摘要

A waveform reproducing unit, connected to a change rate adjustment unit, a ROM (30) and a RAM (40), generates output waveform data which is the temporally compressed or expanded version of the original waveform data by reproducing the stored frequency data and the amplitude data according to the adjusted temporal change rates. The change rate adjustment unit is connected to a frequency data converter to adjust the temporal change rates of the frequency and amplitude data. An Independent claim is also included for a compressed or expanded waveform generating method.
