Abstract

An information processing method includes: obtaining a position of a user within the three-dimensional sound field; determining a virtual boundary that includes two or more lattice points surrounding the user, based on the position of the user which has been obtained, the two or more lattice points being among a plurality of lattice points set at predetermined intervals within the three-dimensional sound reading field; the propagation characteristics of the sound from the sound source to the two or more lattice points included in the virtual boundary determined; calculating transfer functions of the sound from the two or more lattice points included in the virtual boundary determined to the position of the user; and generating the output sound signal by processing the sound information using the propagation characteristics read and the transfer functions calculated.
