PURPOSE:To realize an acoustic field having a sense of spread due to a resonance system by controlling the extent of delay of a waveform signal in each of plural bands to add the effect. CONSTITUTION:Plural monaural waveform signal have acoustic images oriented as plural channel waveform signals by an acoustic image orienting means 7 and are divided to waveform signals in plural bands by band dividing means 8a to 8c. The extent of delay of the waveform signal in each of plural bands is controlled to add the effect by plural effect adding means 9. Output signals of plural effect adding means 9 are mixed with respect to each channel by plural mixing means 13a to 13c. Thus, acoustic image orientation and the prescribed effect are added to plural monaural waveform signals in each channel, and the acoustic field having a sense of spread is obtained. |
