摘要:
A prediction error calculating unit 13 calculates an error signal 103 between a left signal l(n) 101 and a prediction signal of the left signal l(n) 101 predicted from a right signal r(n) 102, a gain adjusting unit 17 makes a gain adjustment and outputs an error signal 107, a first adder 14 adds the left signal l(n) 101 and the error signal 107 and outputs, and a second adder 15 adds the right signal r(n) 102 and the error signal 107 in opposite phase and outputs.
