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.

Abstract: An information processing system (a) acquires user playing data indicative of playing of a piece of music by a user, (b) generates habit data indicative of a playing habit of the user in playing the piece of music on a musical instrument, by inputting the acquired user playing data into at least one first trained model that learns a relationship between (i) player playing training data indicative of playing of a piece of reference music by a player, and (ii) corresponding training habit data indicative of a playing habit of the player in playing the piece of reference music on a musical instrument, the playing habit being indicated by the player playing training data; and (c) identifies a practice phrase based on the generated habit data.
