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.

Abstract: A data output method according to one embodiment includes: sequentially acquiring input data related to a musical playing operation; obtaining a plurality of estimation information including first estimation information and second estimation information by providing the input data to a plurality of estimation models including a first estimation model and a second estimation model; identifying a musical score playing position based on the plurality of estimation information; and reproducing and outputting predetermined data based on the musical score playing position. The first estimation model indicates a relationship between performance data relating to the performance operation and a sheet music position in prescribed sheet music. The second estimation model is obtained by learning a relationship between the performance data and an intra-measure position.
