Abstract

An audio signal processing method executed by an audio signal processing device includes: obtaining an audio signal having an attribute that includes information indicating an indirect sound; calculating a first sound volume, the first sound volume being based on a sound volume of the indirect sound when the indirect sound arrives at a listening position that is a position where a listener is present, the calculating being based on: a first correction characteristic obtained by correcting, using a frequency characteristic indicating auditory sensitivity, a gain characteristic of each predetermined frequency bandwidth related to the indirect sound; and the audio signal obtained; calculating a second sound volume, the second sound volume being based on a sound volume of a direct sound, associated with the indirect sound, when the direct sound arrives at the listening position; selecting whether to output an output signal that is based on the audio signal obtained, based on: a sound volume ratio between the second sound volume calculated and the first sound volume calculated; and a time difference between when the direct sound and the indirect sound arrive; and outputting the output signal, when outputting the output signal is selected.
