PROBLEM TO BE SOLVED: To obtain high-quality reverberated sounds by a small-scale hardware.;SOLUTION: TSP signals as a measuring signal are generated N times by a signal generation part 90, and are supplied to a sheet iron echo device 92. The reverberated sounds generated by the device 92 according to the TSP signals are made even, synchronized, and added N times based on a start point of the TSP signals by a synchronous adder 94. The TSP signals are converted into impulse signals by being divided by signals having inverse characteristics. The added results in the synchronous adder 94 are supplied to an impulse response conversion part 95, and are divided by the inverse characteristics of the TSP signals, whereby the added reverberated sounds are converted into impulse response. Impulse response data obtained by the conversion part 95 are recorded in, e.g. CD-ROMs, and are provided for a reverberated sound adder. In the reverberated sound adder, the impulse response recorded in the CD-ROM is reproduced and input signals are folded therein, so that the reverberated sounds by the sheet iron echoer 92 can be reenacted.;COPYRIGHT: (C)2000,JPO
