<P>PROBLEM TO BE SOLVED: To provide an acoustic generator in which a speaker is hardly normalized and speaker playback with a sense of depth can be performed. <P>SOLUTION: When an acoustic generator 1 is operated, filters 4-1, 4-2, ..., 4-9 perform signal processing to apply 10 kinds of delay effects to an audio signal Sa in accordance with delay times and amplification factors being set, respectively, generate signals Sb1, Sb2, ..., Sb9 and output them to amplifiers 3-1, 3-2, ..., 3-9. The 10 kinds of delay effects are then discharged from nine different speakers at random delay times, thereby eliminating a sense of normalization to the speakers and generating a sense of depth. <P>COPYRIGHT: (C)2008,JPO&INPIT |
