An operational information obtaining section of a music reproduction device obtains operational information which corresponds to a user's operation and represents an instruction on an action of a reproduction section for reproducing data of a musical composition. A selection condition calculation section changes, during the musical composition being reproduced by the reproduction section, relative merits of attribute information relating to the data of the musical composition in accordance with details of the operational information obtained by the operational information obtaining section, and then calculates, based on the relative merits of the attribute information, a condition for selecting the data of the musical composition to be reproduced by the reproduction section. The relative merits of the attribute information, which is information relating to the data of the musical composition, is changed in accordance with the user's operational information, and selection is performed in accordance with the relative merits of the attribute information, whereby it is possible, with the user's simple operation, to reproduce only the musical composition which is desired to be listened to.

Music reproduction device, method, storage medium, and integrated circuit

A scale information inputting section receives an input of scale information of a musical composition. Based on the scale information of the musical composition inputted to the scale information inputting section, an appearance probability calculating section calculates appearance probabilities of pitch names included in the scale information for each of the pitch names. A template storing section stores 24 types of previously created templates respectively corresponding to 24 types of keys. Based on an appearance probability distribution of the musical composition calculated by the appearance probability calculating section and each of the templates stored in the template storing section, a load ratio calculating section calculates load ratios respectively corresponding to the templates. A tonal information detecting section detects, as tonal information of the musical composition, information indicating the load ratios calculated by the load ratio calculating section as a set, or information calculated based on the set of the load ratios.

Musical composition processing device

A music information calculation apparatus recognizing a structure of a piece of music based on an acoustic signal. The apparatus includes: an acoustic signal input for inputting the acoustic signal of the piece of music; an acoustic parameter calculator for calculating, using the acoustic signal, at least a first acoustic parameter indicating a volume of the piece of music; an inflection degree calculator for calculating, using at least the first acoustic parameter, an inflection degree indicating an inflection of the piece of music; a story node calculator for calculating, using at least the first acoustic parameter, a story node representing a time at which a formation of the piece of music changes; and a story information calculator for calculating, as story information indicating at least a correspondence between the story node having been calculated and the inflection degree obtained at the time represented by the story node.

Music information calculation apparatus and music reproduction apparatus

The present invention implements a method and an apparatus for retrieving a sound data desired by the user on the basis of its subjective impression over the sound data. The subjective impression on the desired sound data is entered by the user and converted to a numerical value. A target sound impression value which is a numerical form of the impression on the sound data is calculated from the numerical value. The target sound impression value is then used as a retrieving key for accessing a sound database where the audio signal and the sound features of a plurality of the sound data are stored. This allows the desired sound data to be retrieved on the basis of the subjective impression of the user on the sound data.

A music selection apparatus includes a music data storage unit, an impression amount storage unit, a music selection priority level storage unit, and a music selection processing unit. The impression amount storage unit stores an impression amount obtained by quantifying a listener's impression of a piece of music, for each piece of music stored in the music data storage unit. The music selection priority level storage unit stores a music selection priority level indicating at least one of a reproduction history and a preference level of a piece of music, for each piece of music. The music selection processing unit performs a music selection process of selecting a piece of music to be reproduced from the pieces of music, using a distance between the pieces of music in an impression space and the music selection priority level, the impression space having coordinate axes composed of components of the impression amount.

Music selection apparatus and music delivery system

The present invention provides a music search device for searching for a tune by using an impression quantity obtained by quantifying a listener's impression of such a tune. A tune database contains at least data of a plurality of tunes and a characteristic quantity obtained by quantifying characteristics of each tune. The tune database includes an adjustment table. A reference table storage section stores a reference table containing a previously obtained set of a characteristic quantity and an impression quantity for each of a plurality of sample tunes. When an adjustment input is received, an updating section adds to the adjustment table a set of a received impression quantity and a characteristic quantity of a tune associated with the received impression quantity, and updates the mapping function based on the adjustment table, to which the set of the impression quantity and the characteristic quantity has been added, and the reference table.

Music search device

The present invention provides a music search system for conducting music search, which allows the user to easily listen to music matched to situation. The music search system includes a music data storage section, a location acquisition section, a parameter converting section, a music search section, and a reproducing section. The music data storage section stores a plurality of pieces of music data so as to be associated with a corresponding one of music parameters. The location acquisition section acquires a situation parameter. The parameter converting section converts the situation parameter acquired by the location acquisition section into the music parameter. The music search section uses the music parameter resulted from conversion by the parameter converting section to search through the plurality of pieces of music data stored in the music storage section and selects a piece of music to be reproduced. The reproducing section reproduces the piece of music selected by the music search section.

A candidate piece specifying unitspecifies, as a first candidate piece, a musical piece whose musical piece parameter includes a first factor that is larger than a first factor of a musical piece currently being played from among musical pieces, and specifies, as a second candidate piece, a musical piece whose first factor is smaller than the first factor of the musical piece currently being played from among the musical pieces. When data of a musical piece is reproduced by a playback unita display control unitcauses musical piece information regarding the first candidate piece and the second candidate piece to be displayed at positions on a display screen that reflect coordinate positions in an impression space formed by the factors of the musical piece parameter. Upon receiving an input from a user of specifying a musical piece indicated by musical piece information displayed on a display devicea playback control unitcontrols data of the specified musical piece so that the data of the specified musical piece is reproduced by the playback unit.

A sound features extracting unit receives a sound signal of a music piece to extract sound features. A peak detecting unit detects a peak time when a cost function calculated by a cost function calculating unit indicates a maximal value, and a peak value thereof. A selecting unit selects a time property indicating sound critical points from the peak time and the peak value. This method allows the user to automatically retrieve sound critical points without having to listen to the sound in advance.
