Description

  The present invention relates to a display method, a music selection method, a display device, an audio device, and a program for presenting information for efficiently searching for a target music piece.

  Conventionally, in order to make it easier to find a target song from a large number of songs, search items such as the age and genre of songs released are displayed one after another, and the corresponding song is extracted based on the user's response There is known a search device that presents the information (for example, Patent Document 1).

JP 2006-133939 A

  By the way, in a DJ device for DJ performance, etc., a mixing operation for mixing a plurality of music pieces is frequently used. For this reason, the subsequent music is often selected while being aware of the connection with the currently played music (preceding music). At this time, it is common to imagine the subsequent music (the DJ has already determined the subsequent music in his head) and search for the target music. In some cases, the candidates are narrowed down.

  Under such circumstances, when the technology of Patent Document 1 is used, there is not much problem if the subsequent music has already been imaged. However, if it is desired to narrow down the candidates while browsing a large number of music, it is not always easy to use. It's not good. For example, in the case of Patent Document 1, it is a method of presenting a corresponding piece of music based on a user's answer. For example, it is possible to know how many songs with a BPM of 100 to 110 exist, but within that range Or the distribution state of the music in the periphery cannot be known. In addition, it is impossible to grasp what kind of music (for example, the distribution state of BPM and KEY of each music) is a large number of music (entire music) that are candidates for selection. In other words, since the method of Patent Document 1 cannot be viewed from the whole music, it is not suitable for a selection method that narrows down the candidates for subsequent music from a vague image among many music.

  In view of the above-described problems, the present invention provides a display method, a music selection method, a display device, an audio device, and a program capable of efficiently narrowing down music candidates after grasping the distribution state of a large number of music pieces. The purpose is to provide.

  The display method of the present invention includes a first display step of displaying a plurality of music distribution screens in which music icon groups corresponding to each music are mapped based on different attributes, and one or more music among the plurality of music distribution screens. On the distribution screen, based on the range specifying step for specifying an arbitrary range and the result of specifying the arbitrary range, a music list display screen that lists the music corresponding to the music icons included in the arbitrary range is displayed. And a second display step.

  The display device of the present invention includes a first display unit that displays a plurality of music distribution screens in which music icon groups corresponding to each music are mapped based on different attributes, and at least one music among the plurality of music distribution screens. On the distribution screen, based on the range designation means for designating an arbitrary range and the result of the specification of the arbitrary range, a music list display screen listing music corresponding to the music icons included in the arbitrary range is displayed. And a second display means.

According to these configurations, an arbitrary range is designated on the music distribution screen, and the music list is displayed based on the designation result, so that the user can select music candidates after grasping the distribution state of the entire music. . In addition, since a plurality of music distribution screens having different attributes are displayed, the user can narrow down music candidates in stages. In this way, since the entire music can be looked down and can be narrowed down by attribute, it is suitable for applications in which candidates for subsequent music are narrowed down with a vague image from a large number of music.
Note that the “music distribution screen” does not necessarily have to be mapped based on one attribute. For example, it may be mapped to a plane coordinate based on two attributes, or may be mapped to a three-dimensional space based on three attributes.
Further, when mapping is performed based on a plurality of attributes, not all attributes need to be different from “a plurality of music distribution screens mapped based on different attributes”. For example, when the first music distribution screen is mapped based on the attribute A and the attribute B, and the second music distribution screen is mapped based on the attribute A and the attribute C, the first music distribution screen The second music distribution screen corresponds to “a plurality of music distribution screens mapped based on different attributes”. That is, each music distribution screen should just have a different attribute or its combination.

  In the above display method, a third display step of displaying a music information screen relating to the preceding music being played back is further executed, and the music distribution screen displays the music icon corresponding to the preceding music as another music icon. It is characterized by being displayed separately.

  According to this configuration, since the music information screen related to the preceding music is displayed, the user can grasp the music information related to the preceding music.

  In the above display method, the music list display screen displays a list for selecting the subsequent music to be played next to the preceding music, and the music distribution screen has a higher mixing affinity between the two music. , Mapping so that the distance between the two corresponding music icons is close, and displaying the music icon corresponding to the subsequent music separately from the music icon corresponding to the preceding music and the other music icons To do.

  According to this structure, the mixing affinity of two corresponding music can be shown by the distance between two music icons on the music distribution screen. Thereby, for example, in a DJ device, when it is desired to perform mixing reproduction of the preceding music and the succeeding music, it is possible to efficiently find the succeeding music suitable for mixing with the preceding music.

  In the above display method, the music distribution screen displays an auxiliary line composed of a plurality of concentric circles centering on the preceding music piece, or an auxiliary image in which the concentric circles are color-coded.

According to this configuration, the user can accurately grasp the mixing affinity of two music pieces by displaying the auxiliary line or the auxiliary image.
The “auxiliary image” may be drawn with a color of a different hue for each concentric circle, or a gradation drawn so that a specific color gradually becomes darker / lighter depending on the diameter of the concentric circle. It may be.

  In the above display method, the music distribution screen displays an axis corresponding to the attribute.

  According to this configuration, the user can designate an arbitrary range by displaying the axis corresponding to the attribute.

  In the above display method, the music distribution screen is zoomed-in or zoomed-out according to a specified arbitrary range.

  According to this configuration, for example, when an arbitrary range is small with respect to the music distribution screen, the music distribution screen is displayed in a zoomed-in display (an arbitrary range is enlarged), or an arbitrary range is displayed on the music distribution screen. When the size is large, the music distribution screen can be displayed in a zoom-out manner (an arbitrary range is reduced and displayed), and the music candidates can be narrowed down efficiently.

  In the above display method, the music list display screen is characterized in that each music is sorted and displayed according to the mixing affinity for the preceding music.

  According to this configuration, since the music list is sorted and displayed in accordance with the mixing affinity for the preceding music, subsequent music suitable for mixing with the preceding music can be efficiently found.

  In the above display method, a sort condition selection step for selecting any sort condition from a plurality of sort conditions including mixing affinity and one or more attributes is further executed. The music is sorted and displayed according to the selected sorting condition.

  According to this configuration, the sort condition can be selected according to the user's preference and the purpose of music selection.

  The music selection method of the present invention is characterized by executing each step in the above display method and a music selection step of selecting any music from the music displayed on the music list display screen.

  According to this configuration, it is possible to realize a music selection method capable of efficiently narrowing down and selecting music candidates using a plurality of music distribution screens mapped according to different attributes.

  In the music selection method described above, the second display step may include any of the music distribution screens when any range is designated on any of the music distribution screens among the plurality of music distribution screens. The music icon included in the arbitrary range specified in the above and other music icons are displayed separately.

  According to this configuration, it is possible to reflect the range designation result in another music distribution screen on the music distribution screen. For example, music icons that are included in an arbitrary range are normally displayed, and music icons that are not included in an arbitrary range are grayed out. Thereby, the music candidates can be narrowed down more efficiently.

  In the music selection method described above, the music distribution screen has one or more attributes among the BPM (Beats Per Minute), the tonality (KEY), the genre, the image (bright / dark, the tone, etc.), the artist name, and the label. It is mapped based on.

  Since these attributes are all related to the ease of mixing (compatibility between songs), for example, if you want to perform mixing playback of the preceding music and the following music on a DJ device, it is suitable for mixing with the preceding music The subsequent music can be searched efficiently.

  The acoustic device of the present invention includes: each means in the display device; a music selection means for selecting any music from the music displayed on the music list display screen; and a playback means for playing back the selected music. , Provided.

According to this configuration, it is possible to realize an audio apparatus that can efficiently narrow down and select music candidates using a plurality of music distribution screens mapped according to different attributes.
The audio device is a concept that includes not only an audio device dedicated to music playback but also a device that can operate as a playback device by installing a dedicated application on a PC or various tablet terminals.

  The program of the present invention causes a computer to execute each step in the above display method or the above music selection method.

  By using this program, it is possible to realize a display method or music selection method capable of efficiently narrowing down music candidates after grasping the distribution state of a large number of music.

In this embodiment, a plurality of music distribution screens 60 corresponding to different attributes are displayed in the music distribution display area Eb of the browse screen D0, and music candidates for searching for the target music are narrowed down using these. Each music distribution screen 60 is a distribution diagram in which music icons 71 corresponding to a large number of music are arranged according to a predetermined mapping rule. The user zooms in on the music distribution screen 60 so that all the music icons 71 can be visually recognized, so that the entire music can be seen from a bird's-eye view. Further, by zooming in on the music distribution screen 60, it is possible to grasp in detail the distribution state of the music icon 71 in the vicinity of a specific attribute parameter. Furthermore, since the corresponding attributes and / or combinations thereof (hereinafter also simply referred to as “mapping rules”) differ depending on each music distribution screen 60, it is possible to grasp the music distribution from various angles, and to efficiently select music candidates. You can narrow down. In the present embodiment, a music artwork having transparency is used as the music icon 71.

  In the present embodiment, the mixing affinity between two pieces of music is displayed in the mixing affinity display area Ee on the browse screen D0. “Mixing affinity” is an index that quantitatively represents the degree of compatibility when two music pieces are mixed and reproduced. That is, if the mixing affinity is high, the two music pieces can be mixed without a sense of incongruity, and if the mixing affinity is low, it means that the music is not suitable for mixing. In this way, by presenting the mixing affinity to the user, even a DJ beginner can easily and quickly select a music piece to realize mixing reproduction.

  The operation unit 12 includes a mouse, a keyboard, a touch pad, and the like, and is used for a user to perform various operations.

I do. Note that the communication form may be wired communication or wireless communication.

  The control unit 15 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and performs various arithmetic processes. Also, display control of the display unit 11 based on the operation of the operation unit 12, information input / output control via the external storage device I / F unit 13 and the communication unit 14, music analysis processing / playback control, and the like are performed.

  The storage unit 16 is composed of a hard disk drive or the like, stores a dedicated application 20 (DJ software) for realizing a file music player, and stores music and music information. “Music piece” refers to a music file (or a path of a music file). “Music information” means BPM (Beats Per Minute), KEY (tonality), identification information (music ID), title, artist, composer, genre, label, album, remixer, artwork image file ( Or image file path), release date (release date), rate (evaluated by user), voice waveform data, presence or absence of music, melody, harmony, rhythm, database registration date, last update date of song file, song length (Playback time), playback history such as playback count and playback date and time. Here, the artwork refers to an album artwork, a music artwork, or an image associated with the music by the user.

  Of these pieces of music accompanying information, BPM, KEY, genre, voice waveform data, presence / absence of musical tone, melody, harmony, rhythm, etc. may be set in advance as part of the music accompanying information. 20 may be obtained from the analysis result of the music file by 20. In addition, the user may input (select) / edit these pieces of information.

  The playback processing unit 17 performs playback processing of the music file under the control of the control unit 15 and outputs the playback signal to the audio output unit 18. The audio output unit 18 includes a DSP (Digital Signal Processor), an amplifier, a speaker, headphones, or the like, and outputs a reproduction signal. Note that an external device may be used as the audio output unit 18.

  Next, the browse screen D0 of the file music player will be described with reference to FIG. The browse screen D0 includes a playback music display area Ea on the upper left of the screen, a music distribution display area Eb on the middle of the screen, a narrowing result display area Ec on the lower left of the screen, a music list display area Ed on the lower right of the screen, and an upper screen. And a right mixing affinity display area Ee.

  The reproduction music display area Ea is an area for displaying the music information (music information display screen) of the currently reproduced music, the artwork display area 51 for displaying the music artwork, the music title name, the artist name, It has a first music information display area 52 that displays the release date, label, composer name, and the like, and a second music information display area 53 that displays BPM, KEY, genre, and the like.

  The music distribution display area Eb is an area for displaying a plurality of attribute-specific music distribution screens 60. The music displayed on each music distribution screen 60 is intended for music stored in the storage unit 16. In this embodiment, the BPM distribution screen 60a (see FIG. 7) in which the music icon 71 is mapped according to BPM, the genre distribution screen 60b (see FIG. 8) in which the music icon 71 is mapped according to the genre, and the music icon 71 according to KEY. When the mapped KEY distribution screen 60c (see FIG. 9) and the BPM / KEY distribution screen 60d (see FIG. 10) in which the music icon 71 is mapped according to BPM and KEY are displayed in the music distribution display area Eb. explain. Note that a music distribution screen 60 based on attributes other than these can be displayed in the music distribution display area Eb (details will be described later). Further, the number of music distribution screens 60 to be displayed is arbitrary.

  The narrowing-down result display area Ec is an area for displaying music icons 71 narrowed down by range designation on each music distribution screen 60. In the present embodiment, the narrowing result is displayed on the music distribution screen 60 mapped based on the same mapping rule as the BPM distribution screen 60a. Hereinafter, the screen displayed in the narrowing-down result display area Ec is referred to as a “narrowing result display screen 60e (see FIG. 11)”.

  The music list display area Ed displays a list of music corresponding to the music icons 71 narrowed down by range specification on each music distribution screen 60. Each piece of music displays a parameter of each attribute in a “title (TITLE)” column or an “artist (ARTIST)” column, and a reduced artwork 57 in a “TITLE” column. The attribute items to be displayed in the music list display area Ed can be arbitrarily selected by the user.

  The mixing affinity display area Ee is a graph showing the mixing affinity between two songs of the music being played (hereinafter referred to as “preceding music”) and the music to be played next (hereinafter referred to as “following music”). This is an area to be displayed. In the present embodiment, the attribute-specific mixing affinity, which is the mixing affinity for each attribute, is displayed by the shape of the radar chart 55 including three axes. For example, the “BPM” axis indicates the mixing affinity for BPM, the “KEY” axis indicates the mixing affinity for tonality, and the “ITEM” axis indicates the mixing affinity for genre or artist. A method for calculating each mixing affinity will be described later.

  Here, the operation of the browse screen D0 will be briefly described. First, the user selects a preceding song from the song list display area Ed using a cursor key or the like. The selected music is displayed as a cursor (illustration, shaded display). Subsequently, when the preceding music is determined by the operation of the enter key or the like, the music information is displayed in the reproduction music display area Ea and the mixing affinity is displayed in the mixing affinity display area Ee. At this time, since the music selected in the music list display area Ed and the music displayed in the reproduction music display area Ea are the same, the mixing affinity for each attribute displayed in the mixing affinity display area Ee. Is the maximum. Further, with the selection of the preceding music, the preceding music mark M1 (see FIG. 7 and the like) indicating the preceding music is superimposed and displayed on each music distribution screen 60 in the music distribution display area Eb.

  Thereafter, in order to select a subsequent music, an arbitrary range is designated on each music distribution screen 60 by a mouse or the like. When the range is designated, the music icons included in the designated range (hereinafter referred to as “designated range 73”) are narrowed down by the AND condition and displayed in the narrowing-down result display area Ec and the music list display area Ed. In the music list display area Ed, when the subsequent music is selected using the cursor key in the same manner as the preceding music, the subsequent music mark M2 indicating the subsequent music is displayed on each music distribution screen 60 in the music distribution display area Eb (FIG. 7). Etc.) are superimposed and displayed. Further, with the selection of subsequent music, the mixing affinity for each attribute displayed in the mixing affinity display area Ee also changes. The user selects a music suitable for mixing reproduction while confirming the mixing affinity display area Ee. Finally, when the enter key is pressed, the music displayed at the cursor is determined as the subsequent music, and mixing reproduction is performed.

  Next, the functional configuration of the PC 10 (file music player) will be described with reference to FIG. The main functions of the PC 10 are parameter storage means 110, music file storage means 120, music information display means 130, music distribution display means 140 (first display means), narrowing result display means 150, music list display means 160. (Second display means), mixing affinity display means 170, attribute selection means 180, range specification means 190, sort condition selection means 210, music selection means 220, rotation operation means 230, and reproduction means 240 are provided.

  Of these units, the parameter storage unit 110 and the music file storage unit 120 are realized by the storage unit 16. The attribute selection unit 180, the range specification unit 190, the sort condition selection unit 210, the music selection unit 220, and the rotation operation unit 230 are realized by the operation unit 12. Each other means is realized by the control of the control unit 15 using the dedicated application 20.

  The parameter storage unit 110 stores attribute parameters of each attribute for each music piece. Examples of the attribute include BPM and KEY (see FIG. 4). For these attribute parameters, information attached to the music file as music accompanying information or information obtained from the analysis result is used. The music file storage unit 120 stores a music file (music audio data) of each music.

  The music information display means 130 displays music information related to the music being played in the playback music display area Ea. Each display means including the music information display means 130 (music distribution display means 140, narrowing result display means 150, music list display means 160, and mixing affinity display means 170) receives necessary attributes from the parameter storage means 110. Get parameters and display them. For example, for the attribute “KEY”, the main KEY parameter (the most frequently detected KEY or the rust portion KEY) of the music is acquired. Also, for the attribute “BPM”, the main BPM parameter (the most frequently detected BPM or the rust portion BPM) of the music is acquired.

  The music distribution display means 140 displays a music distribution screen 60 in which music icon 71 groups corresponding to each music are mapped according to a predetermined mapping rule in the music distribution display area Eb. Here, the “mapping rule” refers to an adopted attribute, a combination of attributes, an axis arrangement, an axis shape (linear axis, circular axis), a music icon 71 arrangement rule, and the like. That is, even if the music distribution screens 60 are mapped according to the same attribute, the mapping rules are considered to be different if the axis arrangement, axis shape, and arrangement rules are different.

  The music distribution display unit 140 displays the music distribution screen 60 corresponding to the attribute selected by the attribute selection unit 180. The attribute selection means 180 selects the attribute of each music distribution screen 60 displayed on the music distribution display area Eb from the attribute candidate list shown in FIG. For example, a plurality of attributes can be selected for one music distribution screen 60. In addition, the arrangement and shape of the shaft can be selected. Furthermore, as an arrangement rule of the music icon 71 when each attribute is selected, one shown in the “arrangement rule” column of FIG.

  In the present embodiment, a plurality of music distribution screen patterns in which attribute-axis arrangement-axis shape are combined in advance are prepared, and one to be displayed in the music distribution display area Eb is selected from them. For example, four patterns of a BPM distribution screen 60a (see FIG. 7), a genre distribution screen 60b (see FIG. 8), a KEY distribution screen 60c (see FIG. 9), and a BPM / KEY distribution screen 60d (see FIG. 10) are prepared. It is conceivable to select one or more patterns from these. As a selection method, the music distribution screen 60 may be scrolled by a left / right key or a flick operation as in a cover flow, for example, or a desired pattern may be selected from the music distribution screen pattern list. Further, the arrangement order of the music distribution screen 60 may be changed by a drag operation.

  Instead of reflecting each attribute parameter on the axis corresponding to each attribute, each attribute parameter may be reflected depending on the display form. For example, the KEY difference may be displayed by the frame color of the music icon 71 on the music distribution screen 60 mapped based on BPM. In this case, the frame color of each music icon 71 may be determined by associating the fifth degree and the hue. According to this configuration, more information (attribute parameters) can be displayed on one music distribution screen 60. In addition, as a method of changing the display form, other methods such as changing the size of the music icon 71, changing the content / shape / color of the icon itself, changing the transparency, and the like can be considered.

  The “fifth degree” refers to a tonality space in which each of the 12 major and minor keys is arranged in an annular shape, and the subgenus is arranged in the clockwise direction and the counterclockwise direction in each key. A combination of major and minor keys located at the same angle is a parallel tone. For this reason, the tonality located closer to the fifth degree includes more common pitches, and dissonance is less likely to occur when mixing.

  Furthermore, as an example of a method of reflecting each attribute parameter depending on the display form, the display form of the music icon 71 may be changed according to the mixing affinity with the preceding music. In this case, the display form may be changed according to the attribute-specific mixing affinity of the attributes adopted in each music distribution screen 60, or a predetermined attribute-specific mixing affinity (for example, the attributes shown in FIG. 6). The display form may be changed according to any one of the candidates.

  The music distribution display means 140 displays the music icon 71 corresponding to the preceding music and the subsequent music separately from the other music icons. In the present embodiment, the music icon 71 corresponding to the preceding music and the subsequent music is distinguished from the other music icons 71 by displaying the preceding music mark M1 and the subsequent music mark M2 in a superimposed manner. In addition to this, the music icon 71 can be distinguished by changing the display form such as adding a frame, enlarging the display, changing the content / shape / color of the icon itself, flashing, and vibrating. It is done.

  The music distribution display means 140 displays the axis corresponding to the attribute of each music distribution screen 60 on each music distribution screen 60. Further, as necessary, the axis name, separator line, scale label, and the like are additionally displayed on each axis. Further, each music distribution screen 60 performs zoom-in display or zoom-out display for each designation of the designated range 73 by the range designating unit 190. For example, when the designated range 73 is small with respect to the music distribution screen 60, the music distribution screen 60 is zoomed in so as to have the maximum size including the designated range 73 (the designated range 73 and the music icon 71 are enlarged and displayed. ). On the contrary, when the designated range 73 is larger than the music distribution screen 60, the music distribution screen 60 is zoomed out so as to have the maximum size including the designated range 73 (the designated range 73 and the music icon 71 are reduced). indicate). Note that it may be possible to select whether or not zoom-in / out display is necessary in accordance with the presetting or how to designate the designated range 73.

  In addition, the music distribution display means 140, when the specified range 73 is specified on any of the music distribution screens 60 among the plurality of music distribution screens 60 displayed in the music distribution display area Eb, the other music distribution screens 60. The music icon 71 included in the designated range 73 designated on any of the music distribution screens 60 and the other music icons 71 are displayed separately. In the present embodiment, for example, when the music icons 71 of A and B are included in the designated range 73 in the first music distribution screen 60 among the music A, B, and C, the second music distribution screen 60 , A and B are normally displayed, and C is grayed out. That is, each time the designated range 73 is set, the number of music icons 71 that are grayed out in each music distribution screen 60 increases.

  The narrowing-down result display means 150 displays the music icon 71 narrowed down based on the range designation result in the music distribution display area Eb in the narrowing-down result display area Ec. For example, when the designated range is not set in the music distribution display area Eb, the BPM distribution screen 60a and the narrowing-down result display screen 60e are the same display (because the mapping rules are common). Further, after the range is designated, only the music icon 71 (music icon 71 not grayed out) normally displayed on the BPM distribution screen 60a is displayed.

  The music list display means 160 displays the music list narrowed down based on the range designation result in the music distribution display area Eb in the music list display area Ed. Further, the music list is sorted and displayed in accordance with the selection by the sort condition selection means 210. The sort condition selection unit 210 selects a sort condition from among the attribute candidates shown in FIG. 4 in addition to “mixing affinity”. For example, when the attribute “BPM” is selected, the BPM is sorted in order of increasing / decreasing BPM. When “mixing affinity” is selected as the sorting condition, an attribute (hereinafter referred to as “vertex attribute”) assigned to the axis located at the vertex of the radar chart 55 by the rotation operation of the radar chart 55 by the rotation operation means 230. Are displayed in the order according to the attribute-specific mixing affinity. For example, in the example of FIG. 2, since the vertex attribute is “BPM”, the respective music candidates are arranged in the order closer to the BPM “100.000” of the music being reproduced. For example, when the vertex attribute is “KEY”, the KEYs are arranged in the order from “BM”, and when the vertex attribute is “ITEM”, they are arranged in descending order of the attribute-specific mixing affinity of “ITEM”. The ascending order and descending order of the array may be switched.

  When “mixing affinity” is selected as the sort condition by the sort condition selection unit 210, the sort condition is not displayed according to the attribute-specific mixing affinity corresponding to the vertex attribute of the radar chart 55, but “total mixing affinity”. It may be sorted and displayed in the order according to “degree”. Here, the “total mixing affinity” can be calculated by a predetermined calculation formula using the attribute-specific mixing affinity as a parameter, such as a total value of attribute-specific mixing affinity.

  The music list display means 160 displays the music to be selected (subsequent music) separately from other music in accordance with the selection operation by the music selection means 220. In the present embodiment, it is assumed that the target music string is shaded in accordance with the selection operation of the music selection means 220 (see FIG. 2).

  The mixing affinity display means 170 displays the mixing affinity of the succeeding music with respect to the preceding music on the radar chart 55. Further, when a rotation operation is performed by the rotation operation means 230, the radar chart 55 is rotated and displayed according to the operation. For example, as shown in FIG. 5, it is conceivable to rotate each axis by 120 ° every time a predetermined key is pressed.

  Here, the attribute-specific mixing affinity will be described. The attribute-specific mixing affinity is determined based on the relative value of the attribute parameter of the subsequent music with respect to the preceding music. As shown in FIG. 6, the attribute “BPM” is calculated from the degree of coincidence or difference between the BPMs of two songs. For example, if the difference in BPM is 1.0 or less, the score is 10 points, and if the difference in BPM is greater than 1.0 and 2.0 or less, it is tabulated to calculate the mixing affinity by attribute. May be. In addition, in the case of the attribute “KEY”, if the KEYs of two music pieces are the same key, the score is 10 points, and in the case of the Major / Minor relationship, the score is 8 points and 5 degrees shifted (both sides on the fifth degree range) and 6 points. You may calculate from a table like a point. Further, in the case of the attribute “ITEM”, for example, +2 points when the artists of the two songs match, +2 points when the genres match, +2 points when the composers match, and when the age is close (for example, 1 Within the year), the attribute-specific mixing affinity may be calculated by adding a score for each attribute item, such as +2.

  Also, in the case of the attribute “volume”, it is conceivable to calculate from the degree of coincidence or difference between the volumes of two music pieces. Further, in the case of the attribute “title”, it may be calculated from the matching degree or difference of title names by character analysis. For example, +2 points when the same word is used in the title names of two music pieces, and +1 point when highly related words (for example, “winter” and “snow”) are used. In addition, the attribute-specific mixing affinity may be calculated by adding points based on the collation result of each word when the title name is divided into phrases.

  The reproduction means 240 reads out the music selected from the music list displayed on the music list display means 160 from the music file storage means 120 and reproduces it.

  Next, the details of the music distribution screen 60 will be described with reference to FIGS. 7 to 10 will be described on the assumption that the range designation results for the other music distribution screens 60 are not reflected (the gray-out display is omitted).

  FIG. 7 is a diagram illustrating a display example of the BPM distribution screen 60a. On the BPM distribution screen 60a, music icons 71 mapped according to the BPM and the number of reproductions and an axis 72 corresponding to the BPM are displayed. Each music icon 71 is arranged on the upper side as the BPM is larger, and is arranged on the left side as the number of reproductions is larger (priority display). When a plurality of music icons 71 are overlapped, the newest reproduction date is displayed on the near side (the uppermost layer). It should be noted that instead of the last playback date, those with a large number of past playbacks, those with a large number of mixed playbacks, and mixing affinities with preceding music (mixing by attribute corresponding to the attribute adopted in each music distribution screen 60) Those having a high affinity or a high total mixing affinity) may be displayed on the front side. In addition, regarding the attribute for determining the priority when a plurality of music icons 71 overlap, the user may be able to select from the plurality of attribute candidates.

  Further, as shown in the figure, the preceding music mark M1 is superimposed on the music icon 71 of the music corresponding to the preceding music, and the subsequent music mark M2 is superimposed on the music icon 71 of the music corresponding to the subsequent music. indicate. The preceding music mark M1 and the subsequent music mark M2 are displayed so as to be distinguishable from each other by color coding or the like.

  Moreover, in the figure, the dotted line frame of the code | symbol 73 has shown the designated range. In the example shown in the figure, the range is specified by drawing a rectangular frame. The range may be specified by a circle or a polygon instead of a rectangular frame. In the case of a touch panel or the like, the range may be specified by a locus drawn by itself. For example, by dragging with the mouse left clicked, a quadrangular frame with the left clicked position as the vertex is drawn. Whether or not it is included in the designated range 73 (whether or not to be narrowed down) may be determined by whether or not the entire music icon 71 is included, or at least a part of the music icon 71 is included. You may determine by whether it is contained. Further, when most of the music icon 71 (a predetermined ratio or more) is included, it may be determined that it is included in the designated range 73.

  FIG. 8 is a diagram showing a display example of the genre distribution screen 60b. On the genre distribution screen 60b, each music icon 71 mapped according to the genre and the number of times of reproduction, a circular frame 75 indicating genre division, and a first circular auxiliary line 85 indicating the distance from the center of the genre distribution screen 60b, , Is displayed. Each music icon 71 is classified for each genre, and arranged so as to be closer to the center as the number of reproductions increases (priority display). The circular frame 75 is displayed in an appropriate size so that the user can grasp the genre classification after mapping each music icon 71. In addition, the genre name is displayed as text in the vicinity of the circular frame 75.

  Similarly to the BPM distribution screen 60a, the preceding music mark M1 and the succeeding music mark M2 are superimposed on the music icons 71 and 71 of the music corresponding to the preceding music and the subsequent music, respectively. Further, in the example of FIG. 8, the range is specified by drawing a circular frame as indicated by reference numeral 73. The range specifying operation is the same as that on the BPM distribution screen 60a. For example, when the mouse is dragged with the mouse left clicked, an elliptical frame based on the left clicked position is drawn. That is, it is not necessary to specify the frame type before the specified range 73 is drawn.

  Instead of the first circular auxiliary line 85 shown in the figure, an “auxiliary image” in which concentric circles are displayed in different colors may be displayed. In this case, the “auxiliary image” may be drawn with colors of different hues for each concentric circle, or may be drawn with gradation so that a specific color gradually becomes darker / lighter depending on the diameter of the concentric circles. There may be.

  FIG. 9 is a diagram illustrating a display example of the KEY distribution screen 60c. In the KEY distribution screen 60c, each music icon 71 mapped according to the KEY and ITEM mix affinity, a straight auxiliary line 76 indicating the KEY classification, and a second circular auxiliary indicating the distance from the center of the KEY distribution screen 60c are displayed. Line 86 is displayed. Each music icon 71 is arranged in the fifth-degree range and thus in a circle, and is arranged closer to the center as the mix affinity of the attribute “ITEM” is higher (priority display). That is, the genre and artist are the same as that of the preceding music, or the closer to the released age, the closer to the center (see FIG. 6).

  Similarly to the BPM distribution screen 60a and the like, the preceding music mark M1 and the succeeding music mark M2 are superimposed on the music icons 71 and 71 of the music corresponding to the preceding music and the subsequent music, respectively. Furthermore, in the example of FIG. 9, as shown by reference numeral 73, the range is specified by specifying a sector area delimited by the straight auxiliary line 76. The designation operation is performed by, for example, performing a left click operation on a desired sector area using a mouse or the like.

  In addition, as shown in the figure, it is possible to designate a plurality of sector regions simultaneously instead of designating only one sector region. Further, instead of the second circular auxiliary line 86 shown in the figure, an “auxiliary image” in which each concentric circle is displayed by color may be displayed.

  FIG. 10 is a diagram showing a display example of the BPM / KEY distribution screen 60d. The BPM / KEY distribution screen 60d shows each music icon 71 mapped according to BPM and KEY, a horizontal axis 78 corresponding to BPM, a vertical axis 79 corresponding to KEY, and KEY and BPM of the preceding music. Two band lines 81 and 82 and a third circular auxiliary line 87 (“auxiliary line” in the claims) indicating the distance from the preceding music mark M1 are displayed. In addition, the arrangement of each music icon 71 in the horizontal direction is determined according to BPM, and the arrangement in the vertical direction is determined according to KEY. A band 81 indicates a predetermined range before and after the BPM of the preceding music, and a band 82 indicates a predetermined range before and after the KEY of the preceding music. That is, the music icon 71 and the preceding music mark M1 corresponding to the preceding music are arranged at the position where the two band lines 81 and 82 intersect. Further, since the third circular auxiliary line 87 is a plurality of concentric circles centering on the music icon 71 corresponding to the preceding music, the mixing affinity based on the BPM / KEY with the preceding music can be grasped at a glance. ing.

  Similarly to the BPM distribution screen 60a and the like, the preceding music mark M1 and the succeeding music mark M2 are superimposed on the music icons 71 and 71 of the music corresponding to the preceding music and the subsequent music, respectively. Furthermore, in the example of FIG. 10, the designated range 73 is designated by drawing a rectangular frame as in the BPM distribution screen 60 a. In addition, on the BPM / KEY distribution screen 60d, instead of the third circular auxiliary line 87, an “auxiliary image” in which each concentric circle is displayed by color may be displayed.

  Further, the arrangement of the band lines 81 and 82 is fixed so that the intersection (preceding music mark M1) of the two band lines 81 and 82 is always a fixed position on the BPM / KEY distribution screen 60d, and the axes 78 and 79 are fixed. The scale label may be changed. For example, when the arrangement of the band lines 81 and 82 is fixed as shown in FIG. 10 and the key of the preceding music is “Gm”, “Gm” is written at the label position of “Bm”. When the BPM of the preceding music is “120”, “120” is written at the label position of “100”. In order to show the correspondence between the music icon 71 of the preceding music piece and the other music icon 71 in an easy-to-understand manner, the two band lines 81 are displayed so that the preceding music mark M1 is displayed substantially at the center of the BPM / KEY distribution screen 60d. , 82 are preferably fixedly displayed.

  As described above, as shown in FIGS. 7 to 10, each music distribution screen 60 is provided with each music icon 71 according to each mapping rule. Moreover, the attribute similarity between music is high, so that the distance between the music icons 71 is small. That is, the ease of mixing reproduction is indicated by the distance between the music icons 71. Furthermore, by displaying the preceding music mark M1 and the subsequent music mark M2 on each music distribution screen 60, it is possible to determine at a glance whether or not the subsequent music selected in the music list display area Ed is really suitable for mixing. can do.

  Next, FIG. 11 is a diagram showing a display example of the narrowing-down result display screen 60e based on the range specifying operation on each music distribution screen 60 shown in FIGS. The narrowing-down result display screen 60e has the same mapping rule as the BPM distribution screen 60a, but is different in that the music icon 71 corresponding to the preceding music is indicated by an icon frame 71a. Further, only the music icon 71 included in the specified range 73 of all the music distribution screens 60 shown in FIG. 7 to FIG. 10 and the music icon 71 corresponding to the preceding music are displayed as the narrowing result, and the others are displayed. It is also different in that it is not displayed (others are grayed out on the BPM distribution screen 60a). When the narrowing-down result shown in the figure is displayed, songs for three songs other than the preceding music are listed in the music list display area Ed (see FIG. 2).

  Next, the flow of the mixing reproduction process will be described with reference to the flowchart of FIG. It is assumed that the preceding music selection operation is performed before the flow starts. When the preceding music selection operation is performed and the reproduction is started, the reproduction music display area Ea is updated (music information regarding the preceding music being reproduced is displayed, S01: third display step), and the music distribution display area The preceding music mark M1 is displayed on each music distribution screen 60 in Eb (S02).

  Thereafter, when a range designation operation is performed in the music distribution display area Eb (S03: range designation step), the narrowing-down result display area Ec and the music list display area Ed are updated by narrowing down the music based on the operation (S04). : Second display step). The refinement result display area Ec and the music list display area Ed are updated every time the designated range 73 is designated.

  Thereafter, when the sort condition for the music list display area Ed is changed (S05: sort condition selection step), the music list display area Ed is updated (S06). In addition, when it is not necessary to change the sorting condition, the steps S05 and S06 are omitted. When the subsequent music is selected from the music list display area Ed (S07: music selection step), the subsequent music mark M2 is displayed on each music distribution screen 60 in the music distribution display area Eb (S08). Further, the mixing affinity display area Ee is updated in accordance with the selection operation of the subsequent music (S09).

  Thereafter, when the user presses the enter key (S10: Yes), the selected music is determined as the subsequent music, and mixing reproduction with the preceding music is performed (S11). Thereafter, the process returns to S01, and the selected succeeding music is reproduced as the preceding music. If the user sees the attribute-specific mixing affinity (radar chart 55) displayed in S09 and determines that it is not suitable as the subsequent music (S10: No), S03, Returning to S05 or S07, another song is selected.

  As described above, according to the present embodiment, the music candidates are narrowed down based on the range designation result on each music distribution screen 60. Therefore, the user selects the music candidates after grasping the distribution state of the entire music. it can. In addition, since a plurality of music distribution screens 60 having different attributes are displayed, the user can narrow down music candidates in stages. In this way, it is possible to look down on the whole music and narrow down by attribute, so if you want to mix and play within DJ performances, narrow down the candidates for subsequent music from a vague image. Convenience is good when going.

  Further, in the music distribution screen 60, the higher the mixing affinity between two music pieces, the closer the distance between the two corresponding music icons 71 is, so that the succeeding music suitable for mixing with the preceding music piece Can be searched efficiently. Further, each music distribution screen 60 reflects the range specification result in the other music distribution screens 60 (the music icon 71 outside the specified range 73 is grayed out), so that the music candidates can be narrowed down more efficiently. Can do.

  Further, in the mixing affinity display area Ee, the attribute-specific mixing affinity of each attribute is displayed on the radar chart 55, so that the attribute-specific mixing affinity for the preceding music can be easily shown to the user. Thereby, the user can determine at a glance whether the selected music is suitable for mixing and in which attribute the mixing is suitable. In addition, a comprehensive evaluation of a plurality of attribute-specific mixing affinities can be indicated by the area in the polygon of the radar chart 55.

  The following modifications may be adopted. For example, in the above-described embodiment, the music distribution screen 60 mapped based on one or two attributes is illustrated, but a music distribution screen 60 mapped based on three or more attributes may be used. Further, the four music distribution screens 60 displayed in the music distribution display area Eb do not necessarily have different mapping rules. For example, a configuration may be used in which two music distribution screens 60 based on the same mapping rule are displayed with different magnification rates.

  In the above embodiment, the music file and the music accompanying information (parameter) are both stored in the storage unit 16, but may be stored in different areas. For example, the PC 10 may be configured to be able to communicate with a first database that manages music files and a second database that manages music accompanying information, and acquires necessary information from each database.

  In the above embodiment, after narrowing down the music candidates, the subsequent music is finally selected from the music list. However, the music icon 71 is double-clicked on each music distribution screen 60. Subsequent music may be selectable by operation. In addition, when selecting the subsequent music, the mixing affinity with the preceding music is calculated, and if the result exceeds the predetermined value, a message such as “This music is suitable for mixing” is displayed, or the calculation result is the predetermined value. In the following cases, a message such as “This song is not suitable for mixing” may be displayed, and advice to the user may be displayed.

  In the above embodiment, the music icons 71 corresponding to all the music stored in the storage unit 16 are displayed on the music distribution screen 60. However, the filtering condition input (for example, text input or condition selection) is performed. You may display what narrowed down by the object. As filtering conditions, genre, artist, album, BPM, playlist, keyword, and the like are conceivable.

  In the above embodiment, the music icons 71 included in the designated range 73 in each music distribution screen 60 are narrowed down by the AND condition, but the music icons 71 are displayed based on other logical operation expressions such as an OR condition. It may be extracted.

  Further, the areas Ea to Ee displayed on the browse screen D0 do not necessarily have to be simultaneously displayed on the same screen. For example, after the music distribution display area Eb is displayed, the narrowing-down result display area Ec and the music list display area Ed are displayed, and after the subsequent music is selected, the mixing affinity display area Ee is displayed. You may pass through a process.

  It is also possible to provide each function of the PC 10 shown in the above embodiment as a program. Further, the program can be provided by being stored in various storage media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each function of the PC 10 and a storage medium storing the program are also included in the scope of rights of the present invention.

  Further, in the above embodiment, the case where the present invention is applied to the PC 10 (file music player) is illustrated, but the present invention is applied to a tablet terminal installed with an audio device dedicated to music playback or a music playback application. Also good.
