Abstract
An audio signal processing method includes generating an initial reflected sound control signal according to a geometrical shape of a virtual space, generating a reverberant sound control signal using a reflected sound parameter of the virtual space, calculating timing of connection, the timing of connection being a point in time at which a volume of an initial reflected sound reproducible by the initial reflected sound control signal is a same as a volume of a reverberant sound reproducible by the reverberant sound control signal, based on the geometrical shape of the virtual space, and increasing, in a period of time before the timing of connection, a level of the reverberant sound control signal so as to cause the volume of the reverberant sound to be closer to the volume of the reverberant sound at the timing of connection.
