Abstract: An audio processing system includes at least one memory storing a program and at least one processor. The processor implements the program to analyze an audio signal including sound from a first sound source; identify, based on the analysis of the audio signal, a series of sound indicators each representing a certainty that audio components of the first sound source are included in the audio signal; identify a series of pitches, each relating to the components of the first sound source; and cause a display device to display the series of the sound indicators and the identified series of the pitches along a common time axis.

Abstract: A computer-implemented reproduction control method includes reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound. The method includes starting reproducing the first sound, continuing the reproduction of a first sound until an end of the first sound in response to receiving a first instruction in a reproduction period of the first sound, stopping the reproduction of the first sound, and after the stopping of the reproduction of the first sound, starting reproducing the second sound in response to receiving a second instruction provided by a user.

Abstract: An information processing method includes generating a change parameter relating to a process in which a temporal relationship between a first motion and a second motion changes, by inputting, into a trained model, first time-series data that represent a content of the first motion, and second time-series data that represent a content of the second motion in parallel to the first motion.

Abstract: A music data processing method includes estimating a performance position within a musical piece, and updating a tempo designated by music data representing a performance content of the musical piece such that a tempo trajectory corresponds to a transition in a degree of dispersion of a performance tempo, which is generated as a result of estimating the performance position with respect to a plurality of performances of the musical piece, and the transition in the degree of dispersion of a reference tempo. The performance tempo is preferentially reflected in a portion of the musical piece in which the degree of dispersion of the performance tempo falls below the degree of dispersion of the reference tempo, and the reference tempo is preferentially reflected in a portion of the musical piece in which the degree of dispersion of the performance tempo exceeds the degree of dispersion of the reference tempo.

Abstract: Musical score acquisition section acquires musical score information representing a musical score of a music piece to be practiced by a user. Target portion setting section sets a plurality of portions of the music piece as target portions for training, respectively. Target musical score acquisition section acquires target musical score information indicative of partial musical scores of the respective target portions for training set by the target portion setting section. Display control section controls, on the basis of the target musical score information acquired by the target musical score acquisition section, a display device to display two or more of target musical scores in a side-by-side arrangement. Thus, a user can easily grasp the plurality of target portions for training.

Abstract: A mapping estimation apparatus includes a mapping adjuster. The mapping adjuster estimates mappings which correlate a plurality of subset data items with respective parts of universal set data including union of the plurality of subset data items based on the plurality of subset data items and the universal set data. The mapping adjuster estimates a mode of selecting a plurality of codomain data items from the universal set data and modes of mappings applied to the plurality of subset data items so as to have a maximum probability that data items obtained by selecting a plurality of codomain data items of which a subset of union is the universal set data from the universal set data and applying the mappings to the plurality of subset data items as domains will be respectively the plurality of codomain data items.

Abstract: A controller of a score displaying apparatus operates in a view mode displaying a score on a screen of a user I/F 12, and a writing mode obtaining information indicating writing on the score via the user I/F 12. In response to one operation specifying one grand staff by a user in the view mode, the controller performs a process of enlarging an image of an image area to which the specified grand staff belongs and displaying the enlarged image on a foreground of a center of the screen, and performs a process of switching a control mode from the view mode to the writing mode.
