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: A measurement method includes generating a plurality of second measurement signals by disposing a plurality of first measurement signals corresponding to each of the plurality of speakers in respective different time zones on a time axis, generating a plurality of third measurement signals by copying a portion of a back end of each of the plurality of second measurement signals and adding the portion to a front end of each of the plurality of second measurement signals, outputting sounds according to each of the plurality of third measurement signals from each of the plurality of speakers, collecting the sounds with a microphone, and calculating a plurality of impulse responses corresponding to the plurality of first measurement signals, based on the collected sound signal collected with the microphone and the plurality of third measurement signals.
