Abstract
In a masker sound generation apparatus, an acquisition part acquires a sound signal, and a generation part generates a masker sound signal based on the acquired sound signal. Specifically, the generation part divides the sound signal acquired by the acquisition part into a plurality of sections each having a predetermined time length, then repeats a sorting process of sorting the divided sections as a process of changing the sequence of arrangement of the sound signal, and alters a manner of sorting the sections each time the sorting process is repeated.
