PROBLEM TO BE SOLVED: To provide an equalizer device that simply sets and reflects appropriate frequency characteristics.SOLUTION: A locus detection section 21 detects a locus of an operation to a detection region. A locus acquisition section 31 acquires the locus detected by the locus detection section 21. A reference gain decision section 32 decides a reference gain in the locus acquired by the locus acquisition section 31 on the basis of the locus acquired by the locus acquisition section 31. An equalizer setting decision section 33 decides an equalizer setting that is a gain in each frequency band in equalizer processing on the basis of the reference gain S and the locus acquired by the locus acquisition section 31. A gain processing section 41 changes the gain according to the reference gain. An equalizer processing section 42 changes the gain of a predetermined frequency band of an input signal according to the equalizer setting. |
