Abstract
A sound-field correction device, comprising: a target calculating unit, a correction amplitude characteristic calculating unit and a setting unit. The target calculating unit calculates, based on a predetermined sound signal, a target amplitude characteristic targeted for sound-field correction by a parametric equalizer and a plurality of auxiliary target amplitude characteristics having amplitude characteristics approximately equal to or gentler than the target amplitude characteristic. The correction amplitude characteristic calculating unit calculates a correction amplitude characteristic for correction sound-field based on the calculated target amplitude characteristic and the calculated plurality of auxiliary target amplitude characteristics. The setting unit sets the parametric equalizer based on the calculated correction amplitude characteristic.
