Abstract
To improve, when area sound pick-up is performed to collect sounds from a sound source in a target area, the sound quality of the collected sounds. The present invention relates to a sound pick-up apparatus that performs area sound pick-up. The sound pick-up apparatus calculates a sound volume level of a mixing signal to mix with a target area sound on the basis of power of estimated noise obtained by estimating background noise included in an input signal input from a microphone array, and power of a non-target area sound, adjusts a sound volume level of the input signal, and a sound volume level of the estimated noise to mix with the mixing signal on the basis of the sound volume level of the calculated mixing signal, and generates and outputs a mixed target area sound with which the input signal that is adjusted to have the calculated sound volume level and the estimated noise that is adjusted to have the calculated sound volume level are mixed.
