PROBLEM TO BE SOLVED: To precisely reproduce a variety of sound field by a simple configuration. SOLUTION: Tow kinds of first and second reflected reverberation sound signal S1 and S2 are generated and outputted from L, R, channel input audio signal LIN, RIN at a reflected reverberation sound generator 2A. Generation conditions for S1 and S2 are changeable independently. The LIN, S1 and S2 are added in weighting with a changeable factor through multipliers 3, 4, 42 and an adder 5A so as to create a front L channel output, and the LIN, S2 and S1 are added in weighting with the changeable factor through multipliers 6, 7, 43 and an adder 8A so as to create a rear L channel output. The audio signal RIN, S1 and S2 are added in weighting with the factor through multipliers 9, 10, 44 and an adder 11A so as to create a front R channel output, and the signal RIN, S2 and S1 are added in weighting with the factor through multipliers 12, 13, 45 and an adder 14A so as to create a rear R channel output. |
