摘要： An audio processing device includes a feature extraction unit and signal generating unit. The feature extraction unit is configured to extract a feature quantity of a first audio signal for each of a plurality of periods. The signal generating unit is configured to for generate a second audio signal by time axis expanding/compressing either a section of the first audio signal in which the feature quantity is steadily maintained for a period time, or a section of the first audio signal in which a fluctuation of the feature quantity is repeated and excluding from the time axis expanding/compressing a section of the first audio signal in which a fluctuation of the feature quantity is not similar to that of other sections of the first audio signal.

摘要： 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.

摘要： 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.

摘要： A music analysis method realized by a computer includes calculating an evaluation index of each of a plurality of structure candidates formed of N analysis points selected in different combinations from K analysis points in an audio signal of a musical piece, and selecting one of the plurality of structure candidates as a boundary of a structure section of the musical piece in accordance with the evaluation index of each of the plurality of structure candidates. N is a natural number greater than or equal to 2 and less than K, and K is a natural number greater than or equal to 2.

摘要： A musical-performance-information transmission method using a first instrument and a second instrument, wherein the first instrument produces sounds in accordance with a user's musical performance and generates musical-performance data in accordance with the produced sounds and the second instrument produces sounds by receiving the musical performance data via a communication means. In the musical-performance-information transmission method, a mixed-sound signal is generated in accordance with a mixture of sounds produced by the first instrument and sounds that are different from the sounds produced by the first instrument, a reference signal is generated in accordance with the sounds produced by the first instrument, and on the basis of the mixed-sound signal and the reference signal, the reference signal is removed from the mixed-sound signal, generating a separated signal, and sound is emitted on the basis of said separated signal.
