Abstract

A sound processing apparatus () is provided with: a directivity synthesis processing unit () for generating a first directivity sound pick-up signal by synthesizing a first sound pick-up signal and a relatively delayed second sound pick-up signal and a second directivity sound pick-up signal by synthesizing a relatively delayed first sound pick-up signal and a second sound pick-up signal; a comparison signal calculation unit () for generating a non-directivity level signal indicating the level of a sum of the directivity sound pick-up signals and a directivity level signal by adding the levels of the directivity sound pick-up signals; a level comparison unit () for acquiring the difference between the levels of the non-directivity level signal and the directivity level signal; and a delay control unit () for adjusting the delay amount such that the difference between the levels becomes smaller.
