Abstract
There are provided a target area sound extraction unit that, based on input signals input from plural microphone arrays, acquires beam former outputs from each of the microphone arrays, and uses the acquired beam former outputs to perform target area sound extraction processing to extract a target area sound taking a target area as a sound source, so as to thereby acquire an area sound acquisition output, and a restoration device that restores components of the target area sound in a frequency bandwidth having a predetermined range that was suppressed in the target area sound extraction processing.
