摘要： A sound field correction apparatus that corrects a sound field characteristic by supplying a measurement signal used for measurement purposes to drive a plurality of speakers arranged at arbitrary positions to reproduce the measurement signal and receiving a collected sound signal obtained by collecting the sound reproduced from the plurality of speakers with a sound collector disposed at an arbitrary listening point is disclosed. The sound field correction apparatus includes: a measurement signal supplier, a receiver, a delay calculator, a sound pressure level difference calculator, a delay correction value calculator, and a gain correction value calculator.
