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 video processing method places an object in a three-dimensional space and outputs a video of a live event as viewed from a viewpoint position set in the three-dimensional space. The video processing method sets a first viewpoint position based on a first factor being a factor related to the object. The video processing method also outputs the video of the live event as viewed from the first viewpoint position, receives a second factor being a factor related to a sound of the live event, and calculates a relative position to the object according to the second factor. The video processing method also changes the first viewpoint position to a second viewpoint position based on the calculated relative position, and outputs the video of the live event as viewed from the second viewpoint position.

Abstract: A sound processing method obtains first audio data representing first sound, obtains second audio data representing second sound created in advance, analyzes the first audio data, compares the second audio data with an analysis result of the analyzing, reproduces third audio data from the second audio data by omitting a type of sound from the second sound that matches a type of sound in the first sound, based on a comparison result of the comparing, and outputs an audio signal representing the reproduced third audio data.
