摘要： In the automatic sound field correcting device, a plurality of audio signals to be reproduced by a plurality of speakers are input, and the signal processing is applied on the corresponding signal transmission paths. The measurement signal is supplied for the respective signal transmission paths, and output by the corresponding speakers. The sound of the output measurement signal is collected and the detection signal of the collected sound is generated. The equalizer gain values are determined based on the detection signals. By determining the identical equalizer gain values for the plural signal transmission paths for which the phases of the audio signals are to be matched, the phases of the signals on those signal transmission paths are matched, and the strange auditory feeling due to the phase mismatch can be reduced.
