Abstract: An audio processing apparatus has a setting processor that sets a size of a virtual sound source; and a signal processor that generates an audio signal by imparting to an audio signal a plurality of head-related transfer characteristics. The plurality of head-related transfer characteristics corresponds to respective points within a range that accords with the size set by the setting processor from among a plurality of points, with each point having a different position relative to a listening point.

Abstract: A method of processing sound includes arranging objects of a plurality of performers in a virtual space. The method also includes receiving a plurality of sound signals respectively corresponding to the plurality of performers. The method also includes obtaining, using a trained model, sound volume adjustment parameters respectively for the plurality of performers. The trained model is trained to learn a relationship between each sound signal, among the plurality of sound signals, that corresponds to each performer of the plurality of performers and each sound volume adjustment parameter, among the sound volume adjustment parameters, that corresponds to the each sound signal. The method also includes adjusting and mixing sound volumes respectively of the plurality of sound signals based on the sound volume adjustment parameters obtained using the trained model.
