Abstract
To perform an efficient and stable area sound pick-up process. The present invention relates to a sound pick-up apparatus. The sound pick-up apparatus according to the present invention includes: a means for acquiring target direction signals on the basis of beamformers of input signals supplied by a plurality of microphone arrays; a means for calculating correction coefficients for approximating target area sound components to each other, the target area sound components being included in the respective target direction signals of the plurality of microphone arrays; a means for selecting a main microphone array on the basis of the correction coefficients, the main microphone array being to be used as a criterion for extracting target area sound; and a means for correcting the target direction signals of the respective microphone arrays by using the correction coefficients with respect to the main microphone array, and extracting the target area sound on the basis of the corrected target direction signals of the respective microphone arrays.
