<P>PROBLEM TO BE SOLVED: To provide a stereo reproducing apparatus which emphasizes a high frequency range without influencing a human voice band, makes localization of a sound image clear, and can use a filter of simple configuration. <P>SOLUTION: This stereo reproducing apparatus includes: an adder 5 which generates a difference signal between an L signal and an R signal to be input; a high-pass filter 6 connected to the output side of the adder 5; gain variable amplifiers (7, R1, R2) which amplify an output signal of the bypass filter 6; an adder 8 which adds output signals of the gain variable amplifiers to an original L signal; and an adder 9 which subtracts the output signals of the gain variable amplifiers from an original R signal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
