<First Embodiment>
FIG. 1 is a block diagram of an information processing apparatus 100 according to a first embodiment of the present invention. The information processing device 100 of the first embodiment is realized by a computer system including a control device 11, a storage device 12, a display device 13, and an input device 14. For example, a portable information terminal such as a mobile phone or a smartphone, or a portable or stationary information terminal such as a personal computer is preferably used as the information processing apparatus 100 of the first embodiment.

The display device 13 is composed of, for example, a liquid crystal display panel, and displays an image instructed by the control device 11. The input device 14 is an input device that receives instructions from the user. Specifically, a plurality of operators that can be operated by the user or a touch panel that detects contact with the display surface of the display device 13 are preferably used as the input device 14. Further, a sound collecting device that receives voice input from the user may be used as the input device 14.

The storage device 12 stores a program executed by the control device 11 and various data used by the control device 11. The storage device 12 is composed of a known recording medium such as a magnetic recording medium or a semiconductor recording medium, or a combination of a plurality of types of recording media. A storage device 12 (for example, cloud storage) separate from the information processing device 100 is prepared, and the control device 11 executes writing and reading to the storage device 12 via a mobile communication network or a communication network such as the Internet. You may. That is, the storage device 12 may be omitted from the information processing device 100.

The storage device 12 of the first embodiment stores an acoustic signal X representing a performance sound of a musical piece. Specifically, an acoustic signal X representing various sounds such as a musical sound produced by a musical instrument or a singing sound uttered by a singer is stored in the storage device 12. The acoustic signal X may be supplied to the information processing apparatus 100 from a reproduction device that reproduces the acoustic signal X recorded on a recording medium such as an optical disk. The acoustic signal X is stored in the storage device 12 as a file of any format.

The control device 11 is, for example, a processing circuit such as a CPU (Central Processing Unit), and controls each element constituting the information processing device 100 in an integrated manner. The control device 11 of the first embodiment has a plurality of functions (signal analysis unit 21, time series) for analyzing the acoustic signal X and displaying the result on the display device 13 by executing the program stored in the storage device 12. The analysis unit 22, the display control unit 23, and the change processing unit 24) are realized. The function of the control device 11 may be realized by a set of a plurality of devices (that is, a system), or a part or all of the functions of the control device 11 may be realized by a dedicated electronic circuit (for example, a signal processing circuit). May be good.

The signal analysis unit 21 generates the code data D by analyzing the acoustic signal X stored in the storage device 12. The code data D is time series data representing a time series of a plurality of code names C in the music represented by the acoustic signal X. Specifically, the code data D designates the code name C for each of the plurality of unit periods in which the music is divided on the time axis. Each unit period is a period of time length defined by the beat point of the music. In the first embodiment, a period corresponding to one measure (that is, a plurality of beats) of a musical piece is exemplified as a unit period. Further, a known music analysis technique is arbitrarily adopted in the process in which the signal analysis unit 21 estimates the time series of a plurality of code names C from the acoustic signal X.

By analyzing the code data D generated by the signal analysis unit 21, the time-series analysis unit 22 analyzes a plurality of periods in which the time-series of a plurality of code names C in the music are similar to each other (hereinafter referred to as “analysis period”). Identify Q. Specifically, as illustrated in FIG. 2, the time-series analysis unit 22 has one period (hereinafter referred to as “designated period”) Qa designated by the user in an operation on the input device 14, and a plurality of Qa in the music. A period (hereinafter referred to as “related period”) Qb in which the time series of the code name C is similar to the specified period Qa is specified as the analysis period Q. In the first embodiment, a plurality of (specifically, three) related periods Qb similar to one designated period Qa are specified. Specifically, the time series analysis unit 22 specifies one related period Qb located before the designated period Qa and two related periods Qb located behind the designated period Qa. Each analysis period Q is a period of time length defined by the beat points of the music. Each analysis period Q of the first embodiment is a period of time length corresponding to one measure (that is, a plurality of beats) of the music. The plurality of analysis periods Q do not overlap each other on the time axis. The method in which the time series analysis unit 22 specifies a plurality of analysis periods Q is arbitrary. For example, the similarity with the time series of a plurality of code names C in the specified period Qa is calculated for each of a plurality of periods in which the music is divided on the time axis, and a predetermined period having a large similarity is set as the related period Qb. It is possible to select.

The display control unit 23 of FIG. 1 causes the display device 13 to display an image. The display control unit 23 of the first embodiment causes the display device 13 to display the presentation screen 30 of FIG. 3 showing the result of the analysis by the time series analysis unit 22. As illustrated in FIG. 3, the presentation screen 30 has a plurality (4 pieces) corresponding to a plurality of analysis periods Q (1 designated period Qa and 3 related periods Qb) specified by the time series analysis unit 22. It is configured to include the time series image 31 of. The time-series image 31 corresponding to any one analysis period Q is an image representing a time series of a plurality of code names C in the analysis period Q.

Each time-series image 31 is an image in which a plurality of unit images 32 corresponding to different unit periods are arranged in the X direction. The X direction is a lateral direction which means the direction of the time axis. The plurality of time-series images 31 are arranged side by side at intervals in the Y direction (specifically, the vertical direction) intersecting the X direction. The X direction is an example of the "first direction", and the Y direction is an example of the "second direction".

As can be understood from the above description, the presentation screen 30 is an image in which a plurality of unit images 32 are arranged in a matrix along the X direction and the Y direction. A frame-shaped image 33, which means that the designated period Qa, is added to one time-series image 31 corresponding to the designated period Qa among the plurality of time-series images 31. The user can change the designated period Qa in the music by appropriately operating the time-series image 31 (for example, moving the time-series image 31 left and right). The time series analysis unit 22 specifies a related period Qb similar to the updated designated period Qa for each update of the designated period Qa.

The m-th (m is a natural number) unit image 32 of the time-series image 31 corresponding to any one analysis period Q is a rectangular image representing the m-th unit period in the analysis period Q. be. A code name C specified by the time series analysis unit 22 for the unit period is added to the unit image 32 corresponding to any one unit period. That is, on the presentation screen 30, a plurality of time-series images 31 in which a plurality of code names C are arranged in the X direction are arranged in parallel in the Y direction. Therefore, the user can visually confirm the time series of the plurality of code names C in each analysis period Q from the time series image 31.

As described above, the result of the analysis by the time series analysis unit 22 is displayed on the presentation screen 30, but the user may want to change the code name C estimated from the acoustic signal X. For example, the user may correct the code name C erroneously estimated from the acoustic signal X. Further, the code name C estimated from the acoustic signal X may be changed to the code name C according to the user's intention or preference. The change processing unit 24 of FIG. 1 changes the code name C arranged on the presentation screen 30 according to an instruction from the user. For example, the user can appropriately operate the input device 14 to select any one unit image 32 and then instruct the changed code name C. The change processing unit 24 changes the code name C designated by the code data D for the unit period of the unit image 32 selected by the user to the changed code name C instructed by the user.

By the way, the time series of the plurality of code names C are similar between the plurality of analysis periods Q. Therefore, as can be understood from FIG. 3, on the presentation screen 30, a plurality of unit images 32 to which code names C that are similar to or match each other are added are arranged in the Y direction. By appropriately operating the input device 14, the user can select a set (hereinafter referred to as "unit image sequence") L of a plurality of unit images 32 arranged along the Y direction. When the unit image sequence L is selected, the display control unit 23 displays a frame-shaped image 34 indicating the unit image sequence L.

In the state where the image 34 is displayed, the user can instruct to collectively change the code name C of the plurality of unit periods corresponding to the unit image string L by appropriately operating the input device 14. Specifically, the user selects the unit image string L and instructs the changed code name C. The change processing unit 24 changes the plurality of code names C designated by the code data D for each of the plurality of unit periods corresponding to the unit image string L selected by the user to the changed code names C instructed by the user. do. That is, in the first embodiment, not only the code name C is individually changed according to the instruction from the user for each unit period, but also a plurality of code names C arranged in the Y direction on the presentation screen 30 are used. It is changed all at once according to the instruction from the person. Therefore, there is an advantage that the burden on the user who tries to edit the chord name C of the music can be reduced as compared with the configuration in which the chord name C needs to be changed individually for each unit period.

FIG. 4 is a flowchart of the process executed by the control device 11. For example, the process of FIG. 4 is started triggered by an instruction from the user to the input device 14. When the process of FIG. 4 is started, the signal analysis unit 21 generates code data D by analyzing the acoustic signal X (Sa1).

The time-series analysis unit 22 specifies a plurality of analysis periods Q from the code data D (Sa2 / time-series analysis processing). Specifically, a designated period Qa according to an instruction from the user and a plurality of related periods Qb in which the time series of the plurality of code names C are similar to the designated period Qa are specified as the analysis period Q. The display control unit 23 causes the display device 13 to display a presentation screen 30 showing a time series of a plurality of code names C for each analysis period Q specified by the time series analysis unit 22 (Sa3 / display control process).

The control device 11 determines whether or not the user has changed Qa for a designated period (Sa4). When the designated period Qa is changed (Sa4: YES), the process of specifying a plurality of related period Qb for the changed designated period Qa (Sa2) and the process of reflecting the change on the presentation screen 30 (Sa3) are executed. Will be done.

When the designated period Qa has not been changed (Sa4: NO), the control device 11 determines whether or not the user has instructed to change the plurality of code names C of the unit image string L (Sa5). When a change of a plurality of code names C in the unit image string L is instructed (Sa5: YES), the change processing unit 24 has a plurality of code names designated by the code data D for each unit period in the unit image string L. C is collectively changed to the code name C specified by the user (Sa6). The display control unit 23 changes the display of the code name C in each unit period in the unit image string L in the presentation screen 30 (Sa7).

The control device 11 determines whether or not the end is instructed by the user (Sa8). When the user instructs the end (Sa8: YES), the process of FIG. 4 is terminated. When the end is not instructed by the user (Sa8: NO), or when the change of the plurality of code names C is not instructed (Sa5: NO), the control device 11 shifts the process to step Sa4.

As described above, each time the designated period Qa is changed, a plurality of analysis period Qs are specified (Sa2) and displayed (Sa3), and a plurality of instructions for changing the code name C of the unit image string L are executed. The change of the code name C (Sa6) and the display of the changed code name C (Sa7) are executed. In FIG. 4, attention was paid to the identification and display of the analysis period Q and the change of the plurality of code names C of the unit image sequence L for convenience, but other operations are also given to the presentation screen 30. For example, the change processing unit 24 may change the code name C of one unit period selected by the user.

<Second Embodiment>
A second embodiment of the present invention will be described. In each of the following examples, for the elements having the same functions as those of the first embodiment, the reference numerals used in the description of the first embodiment will be diverted and detailed description of each will be omitted as appropriate.

As illustrated in FIG. 5, the display control unit 23 of the second embodiment displays a plurality of operation images 35 corresponding to different time-series images 31 on the presentation screen 30 in addition to the same elements as those of the first embodiment. Deploy. Each operation image 35 is an image showing permission / prohibition of change for each of the plurality of code names C of each time series image 31. By operating any one operation image 35 corresponding to the time-series image 31, the user can set permission / prohibition of change for a plurality of code names C corresponding to the time-series image 31. Is.

Specifically, when the user is instructed to change a plurality of code names C in the unit image string L (Sa5: YES), the change processing unit 24 permits the operation image 35 among the plurality of code names C. Each code name C shown is changed according to the instruction from the user (Sa6). On the other hand, among the plurality of code names C, each code name C whose operation image 35 indicates prohibition is not changed. The time-series image 31 for which change is permitted and the time-series image 31 for which change is prohibited are displayed in different display modes (for example, color, gradation, or pattern). FIG. 5 illustrates a case where changes are permitted for the time-series images 31 in the first to third rows and changes are prohibited for the time-series images 31 in the fourth row. Therefore, the time-series image 31 in the fourth row has a different display mode from the time-series images 31 in the first to third rows.

As illustrated in FIG. 6, the presentation screen 30 of the third embodiment arranges the modulation image 36 showing the modulation period in the music on the presentation screen 30 in addition to the same elements as those of the first embodiment. The modulation period is a section in which the key is transposed from the initial or basic key of the music to another key. For example, the user arbitrarily specifies the modulation period by operating the input device 14. It is also possible to specify multiple modulation periods in a song. Specifically, the user specifies the start point and the end point of the modulation period and the degree of modulation (hereinafter referred to as "modulation degree") M. The modulation degree M is specified by a pitch such as a semitone lowering, and is displayed in the vicinity of the start point of the modulation image 36. On the other hand, the user can cancel the modulation period by appropriately operating the input device 14. When the modulation period is canceled, the modulation image 36 and the modulation degree M corresponding to the modulation period are deleted.

The modulation image 36 is a linear image extending from the start point to the end point of the modulation period. Specifically, among the plurality of unit images 32 constituting each time-series image 31, the modulation image 36 is displayed along the edge in the X direction in each unit image 32 corresponding to each unit period within the modulation period. .. That is, the transposed image 36 is displayed along the time series of the plurality of code names C in each time series image 31. Further, the code name C displayed on each unit image 32 in the third embodiment is the code name C before the modulation. That is, not only the code name C outside the modulation period is the code name C that has not been transposed, but also the code name C within the modulation period is the code name C that has not been transposed.

The same effect as that of the first embodiment is realized in the third embodiment. Further, in the third embodiment, since the modulation image 36 showing the modulation period in the music is displayed along the time series of the plurality of code names C, the modulation period in the music is displayed together with the time series of the plurality of code names C. It has the advantage that the user can intuitively and visually grasp it. The configuration of the second embodiment in which the permission / prohibition of the change of the code name C can be set by the operation image 35 may be applied to the third embodiment.

In the third embodiment, the code name C before the modulation is displayed also for the modulation period. In contrast to the third embodiment, in the fourth embodiment, the code name C within the modulation period is the code name C after the modulation. That is, when the user specifies the modulation period by operating the input device 14, the change processing unit 24 assigns the code name C specified by the code data D for each unit period within the modulation period to the modulation degree M specified by the user. Change to the code name C that has been transposed. The display control unit 23 causes the display device 13 to display the code name C (that is, the code name C that has been transposed) after the change by the change processing unit 24. On the other hand, when the modulation period is canceled, the change processing unit 24 changes the code name C designated for each unit period within the modulation period to the code name C before the modulation. Further, the display control unit 23 erases the modulation image and changes the code name C of each unit period displayed on the presentation image 30 to the code name C before the modulation.

The same effect as that of the first embodiment is realized in the fourth embodiment. Further, in the fourth embodiment, since the code name C obtained by transposing the code name C represented by the code data D is displayed, there is an advantage that the user can easily grasp the code name C after the transposition. The configuration of the second embodiment in which the permission / prohibition of the change of the code name C can be set by the operation image 35 may be applied to the fourth embodiment.
