Abstract: A performance recording system includes at least one memory and at least one processor. The at least one processor is configured to determine a plurality of candidate regions in a target capture area of a camera by use of first captured imagery generated by the camera configured to capture a plurality of players in a first playing of a piece of music. The at least one processor is configured to select a target area from among the plurality of candidate regions. The at least one processor is configured to extract, from a performance record, a portion corresponding to the target area, the performance record being obtained by capturing the plurality of players in a second playing of the piece of music or being obtained by receiving sounds produced in the second playing.

Abstract: A performance sound generation method includes acquiring image information of a first instrument and acoustic information of the first instrument that changes in accordance with an environment change of the first instrument, acquiring performance operation information of a user, rendering an image of the first instrument based on the image information, and generating a performance sound of the first instrument based on the performance operation information and the acoustic information.

Abstract: A sound processing method includes receiving sound information containing a sound signal of a sound source and position information of the sound source, applying, to the sound signal of the sound source, a first localization process in which a sound image of a direct sound of the sound source is localized based on the position information of the sound source, applying, to the sound signal of the sound source, a second localization process in which the sound image of an indirect sound of the sound source is localized based on the position information of the sound source, receiving a condition related to the sound source or a space, and selecting object-based processing or channel-based processing based on the condition to apply the second localization process.
