PURPOSE:To move sound image localization by controlling the sound image localization of an input acoustic signal according to variation of an envelope signal and outputting it. CONSTITUTION:A multiplier 352 multiplies a 1st LFO waveform W (LF1) and a 2nd envelope waveform W (ENV2) and outputs the multiplication output as a right-ch envelope halfway value W (WK1) to an adder 353, and a multiplier 351 multiplies a 2nd LF2 and 1st ENV1 and outputs the multiplication result to the adder 353, which adds both multiplication results and outputs the result as a right-ch envelope output W (EVR) to a right-ch multiplying process circuit 370. The multiplier 361 of a left-ch multiplying process circuit 360 multiplies a left-ch envelope output W (EVL) by an input waveform W (INP) and outputs a left-ch output W (OTL). Further, the multiplier 371 of the right-ch multiplying process circuit 370 multiplies the right-ch envelope output W (EVR) by the input waveform (INP) and outputs a right-ch output W (OTR). |
