Automatic sound field correcting device

摘要

An automatic sound field correcting device (2) applies signal processing onto audio signals of plural channels and outputs processed audio signals to corresponding plural speakers (6). The automatic sound field correcting device includes: a noise measuring unit (8) for measuring environmental noise level; a signal level determining unit (12) for determining a measurement signal level based on the environmental noise level; and a correcting unit (20) for outputting a measurement signal having the determined measurement signal level to perform automatic sound field correction.
