摘要：
A sound-field correction device, comprising: a target calculating means that 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; a correction amplitude characteristic calculating means that calculates a correction amplitude characteristic for correcting sound-filed based on the calculated target amplitude characteristic and the plurality of auxiliary target amplitude characteristics; and a setting means that sets the parametric equalizer based on the calculated correction amplitude characteristic.
