Description

  The present invention relates to an audio device that stores a music file in association with the attribute information, a program that causes a computer to function as control means in the audio device, and a music file storage method that stores a music file in association with the attribute information.

  2. Description of the Related Art Conventionally, in audio devices, personal computers, portable audio devices and the like equipped with a large-capacity storage device, music data is ripped from a purchased CD, stored in the large-capacity storage device, and the music is listened to. At the time of ripping, various pieces of attribute information are given as metadata to each music file to be generated. For example, if the generated music file is in the MP3 format, information such as artist name, song name, album name, year of creation or release, comment, genre, etc. is recorded in the accompanying ID3 tag. These pieces of information are acquired as album information by referring to a database such as a CDDB (CD database) based on information that can identify the CD such as TOC information.

  In the case of handling a music file in such an audio device or an application program for managing and transferring music files stored in the audio device or the like, one album name is given as metadata to one music file. . Therefore, for example, when ripping a plurality of albums of the same artist, if the same music is recorded in each of different albums, separate music files to which the respective album names are assigned are also included for that music. Generated.

  FIG. 7 is a flowchart showing ripping processing in such a conventional audio apparatus or the like. In this process, ripping is performed on each music file generated by ripping while adding attribute information on each music based on album information acquired by the CDDB. That is, when the process is started, first, in step 71, the TOC information of the CD is read. Next, in step 72, the CDDB is accessed based on the TOC information, and the album information of the CD is acquired. Next, in steps 73 to 76, the music data included in the CD is sequentially ripped. At that time, attribute information such as a song name and album name is added as tag information to each music file to be generated based on the acquired album information. If it is determined in step 75 that ripping has been completed for all music data, the ripping process in FIG. 7 is terminated.

  In addition, when the file name of the music file to be generated is exactly the same as the file name of the music file that already exists in the audio device or the like, for the music file, an instruction to overwrite or not rip is accepted. Process according to the instructions. Alternatively, “Copy” or the like is added to the beginning of the file name, the file name is changed, and ripping is performed. On the other hand, if both file names are different by even one character, such as “.mp3” and “.wma”, for example, ripping is performed with the file name as it is.

  Patent Document 1 describes a technique related to a playback apparatus that plays back a stored music file. In this technique, music file classification, display, search, and the like are performed based on tag information of each music file.

  However, according to the prior art shown in FIG. 7, when the same music is recorded in the albums of a plurality of CDs to be ripped, the music is also ripped as different music files and each album name is attached. Therefore, the same music file is duplicated. For example, this corresponds to the case where a single album, album, and best album with different album names are released for the same song. In addition, when ripping is performed for different music formats such as MP3, AAC, WMA, etc. for the same song, or when the file name of the music file generated due to the difference in the ripping software and how to assign the song name accompanying it are different, There is a possibility that duplicate music files exist for the same music.

  Also, the confirmation of duplication of music is often done only with the file name, but in that case, if there is exactly the same file name, you will be asked to confirm whether or not to overwrite, but on the contrary, If the file name is the same, it means that confirmation of overwriting is required even for different songs. For example, if the file name is composed only of a simple character string such as an enumeration of numbers or an artist name such as “3.mp3” or “toto_3.wma”, even if it is a different song, The possibility of duplicate names increases.

  As described above, when there are duplicate music files for the same music, it cannot be said that the storage capacity for storing the music files is efficiently used. In addition, when file names overlap for the same music or different music, a plurality of names are enumerated for the same music or different music are listed with the same file name, making it difficult to select music. Also, the management of music files becomes complicated.

  An object of the present invention is to eliminate the inconvenience due to the existence of a music file for each album of the same music in different albums in the audio apparatus in view of the problems of the prior art.

  To achieve this object, an audio device according to a first aspect of the present invention is an audio device comprising control means for storing a song file in a predetermined storage area in association with attribute information including information on the song name and album name. When the control means tries to store a new music file together with the attribute information in the storage area, the predetermined other attribute is the same in addition to the new music file and the music name. It is determined whether or not a music file with a different album name already exists in the storage area, and if it is determined that it exists, instead of storing the new music file, the attribute information of the existing music file is The album name of the new music file is added.

  The audio device according to a second invention is the audio device according to the first invention, wherein the storage of the new music file is performed at the time of ripping, and the attribute information of the new music file is recorded on the ripping source medium. It is obtained by referring to a predetermined database based on data.

  The audio device according to a third invention is the audio device according to the first or second invention, wherein the storage of the new music file is performed when the music file is transferred to the storage area. The attribute information is stored in association with the new music file before transfer, or is acquired from a predetermined database at the time of transfer.

  An audio device according to a fourth invention is the audio device according to any one of the first to third inventions, wherein the attribute information includes a track number, and when the album name of the new song file is added, the new song The track number of the file is also added.

  An audio device according to a fifth invention is characterized in that, in any one of the first to fourth inventions, the attribute information includes artist information, and the predetermined other attribute is an artist name. To do.

  The audio device according to a sixth invention is the audio device according to any one of the first to fifth inventions, wherein the album name is added to the attribute information of the existing music file by adding the album name as metadata of the music file. It is characterized by being recorded by recording.

  A program according to a seventh invention causes a computer to function as control means in the audio apparatus according to any one of the first to sixth inventions.

  A music file storage method according to an eighth invention is a music file storage method comprising a control step of storing a music file in a predetermined storage area in association with attribute information including the music name and album name, In the control step, when a new music file is to be stored in the storage area together with the attribute information, the new music file and the music title or a predetermined other attribute in addition to the new music file are the same and the album It is determined whether or not a music file having a different name already exists in the storage area, and if it is determined that it exists, the attribute information of the existing music file is replaced with the attribute information of the existing music file instead of storing the new music file. The album name of a new music file is added.

  According to the present invention, it is possible to eliminate the inconvenience due to the existence of a music file for each album for the same music in different albums.

It is a block diagram which shows the structure of the audio apparatus which concerns on one Embodiment of this invention. It is a flowchart which shows the ripping process in the apparatus of FIG. It is a figure which shows an example of the change in the memory | storage part of the apparatus of FIG. 1 before and after the ripping process of FIG. It is a figure which shows an example of the display screen in the display part of the apparatus of FIG. 1 in the case of reproducing | regenerating about the selected album. It is a flowchart which shows another example of the ripping process in the apparatus of FIG. It is a figure for demonstrating the database used in the other ripping process by the apparatus of FIG. It is a flowchart which shows the ripping process in the conventional audio apparatus etc.

  FIG. 1 is a block diagram showing a configuration of an audio apparatus according to an embodiment of the present invention. As shown in the figure, this apparatus has a CPU 11 that controls each part of the apparatus, a DA converter 12 that converts a digital audio signal from the CPU 11 into an analog audio signal, and reads out data recorded on a CD and outputs an analog audio signal A selector unit 15 that selects and outputs one of the inputs from the CD unit 13, the tuner unit 14 that receives broadcast radio waves and outputs an analog audio signal, the DA converter 12, the CD unit 13, and the tuner unit 14; An amplifying unit 16 that amplifies the analog audio signal from the selector 15, an output unit 17 that outputs the audio signal amplified by the amplifying unit 16 or audio based on the audio signal, and an operating unit 18 for giving an operation instruction to the CPU 11. A display unit 19 for displaying an image based on image data from the CPU 11, a storage unit 20 accessed by the CPU 11, and The rush memory 21, the interface unit 22 for the CPU 11 to access the external device, the microphone terminal 23 for connecting the microphone, and the analog audio signal from the microphone connected to the microphone terminal 23 are converted into a digital audio signal to convert the CPU 11. An AD converter 24 is provided.

  Examples of the storage unit 20 include an internal hard disk, an internal memory, an external hard disk, and an external memory such as a USB memory and a memory card. The storage unit 20 stores music files, programs, necessary databases, and the like. The interface unit 22 corresponds to, for example, a USB interface for connecting a DAP (digital audio player) or the like, or an interface for network connection such as a LAN interface. The output unit 17 includes a headphone terminal, a speaker or a speaker terminal, or an external output terminal. The operation unit 18 is used by a user to operate the audio apparatus, and includes an operation button, an optical operation device, a touch screen, a keyboard, and the like. The display unit 19 displays the operation state of the audio device, file names, selection items, and the like.

  The operation unit 18 and the display unit 19 constitute a user interface, and the user can give necessary instructions to the CPU 11 via the operation unit 18 while viewing the display on the display unit 19. The CPU 11 can selectively switch the audio signal from the CD unit 13, the tuner unit 14, or the DAC 12 by the selector 15 according to the given instruction, and supply the audio signal to the amplifier unit 16 for output. The CPU 11 can also read music data and recording data from the storage unit 20 and the flash memory 21, perform necessary signal processing, and supply a digital audio signal to the DA converter 12. When the CPU 11 is further instructed to perform recording using a microphone, the digital audio signal input through the microphone terminal 23 and the AD converter 24 is subjected to processing such as encoding into data of a predetermined format, Recording from the microphone is performed by writing into the storage unit 20 or the flash memory 21.

  The CPU 11 can also perform ripping, music file management, transfer, and the like according to a predetermined program. The music file generated by the ripping is stored in the storage unit 20. At the time of ripping, album information is acquired from CDDB (CD database), and attribute information such as album name and song name included in the album information is recorded as tag information (metadata) of the music file to be generated. The album information is acquired from the CDDB in a predetermined server on the external network via the I / F unit 22. Alternatively, it may be acquired from a database stored in advance in the storage unit 20.

  FIG. 2 is a flowchart showing ripping processing in the apparatus of FIG. This processing is performed by the CPU 11 according to a predetermined program. In this ripping process, when trying to generate a new music file by ripping, if a music file with the same music and a different album name already exists, instead of generating a new music file, The album name that should have been added to the new music file is recorded in the comment field in the tag information of the existing music file.

  That is, when the process is started, the CPU 11 first reads the TOC of the CD loaded in the CD unit 13 in step 21. Next, in step 22, based on information such as the number of songs in the TOC and performance time, album information about the CD is acquired from a server on the external network or the CDDB provided in the storage unit 20. The album information includes information such as the album name of the CD, the name of the music included in the CD, and the artist associated with the album.

  Next, in step 23, a music file related to the same music as the music in the CD, that is, a music file in which the same music name as each music name in the acquired album information is recorded in the music name column of the tag information is stored in the storage unit 20. Determine if already exists at. At that time, the music that already has a music file with the same music name and the existing music file are stored as a comparison result. Here, only the song titles are compared, and if the song names are the same, the songs are considered to be the same, but the artist is also compared, and if the song name and artist are the same, the songs are the same It may be considered that. If it is determined that the corresponding music file already exists, it is determined in step 24 whether or not the album name in the tag information of the music file is the same as the album name in the acquired album information.

  If it is determined that they are the same, each music file for the album with that album name is considered to already exist in the storage unit 20, and in this case, there is no need to rip, so the processing of FIG. . If it is determined that they are not the same, in step 25, based on the stored comparison result, the music data of the music on the CD for which the music file relating to the same music does not exist in the storage unit 20 is ripped. To do. That is, among the song names in the acquired album information, the song data corresponding to the song names in which the same song name is recorded in the song name column of the tag information but does not exist in the storage unit 20 are ripped. At that time, in the tag information of each music file generated by ripping, information such as album name, corresponding music title, track number, artist, etc. is recorded based on the album information.

  For each piece of music that is not ripped, the necessary information is added to the existing music file related to the same music. That is, among the song names in the album information, for the song data in which the song file in which the same song name is recorded in the song name column of the tag information exists in the storage unit 20, the album name and its track number are set based on the album information. The second album name and the second track number are recorded in the comment field in the tag information of the music file related to the same music.

  Next, in step 26, information such as the album name and each song name in the album information is registered in a predetermined database, and the ripping process in FIG. 2 is terminated. This database is for registering and managing each album stored in the storage unit 20 and music belonging to each album in association with each other.

  On the other hand, if it is determined in step 23 that no music file related to the same music as the music on the CD exists in the storage unit 20, all music data on the CD is ripped in step 27. In the tag information of each music file generated by ripping, based on the album information acquired in step 22, information such as album name, corresponding music title, track number, artist, etc. is recorded. Thereafter, in step 26, registration into the database is performed in the same manner as described above, and the ripping process in FIG. 2 is terminated.

  FIG. 3 shows an example of changes in the storage unit 20 before and after the ripping process. FIG. 4A shows the contents of each existing music file stored in the storage unit 20 before the ripping process and the tag information attached to each music file, and FIG. FIG. 4C shows a part of the contents of the album information acquired for the CD to be ripped by the above, and FIG. 8C shows each music file and each music file stored in the storage unit 20 after performing the ripping process. It shows the contents of the accompanying tag information. The contents of the album information in FIG. 5B are “AAAAA” for the artist, “AAAA-Best” for the album name, and “GGGGGG”, “DDDDD”, “AABBCC”, “AABBCC”, “Track numbers 1 to 5” in this order. rraarr "and" ppqqrr ".

  When the ripping process is performed on this CD, as shown in FIG. 6A, there are existing song files in which the same song name is recorded in the tag information for the song names “AABBCC” and “ppqqrr”. However, the album name “AAAA-Best” is different from the album names “AABBCC” and “PPQQRR” of the existing music file (step 24). Therefore, ripping is performed for CD data corresponding to the song titles “GGGGGG”, “DDDDD”, and “rararr” that do not have the same song title (step 25). Also, the CD data corresponding to the song names “AABBCC” and “ppqqrr” in which the same song name exists is not ripped, and instead the song names are “AABCCC” and “ppqqrr” as shown in FIG. In the comment field in the tag information of a certain existing music file, the track names corresponding to the album name “AAAA-Best” and the song names “AABBCC” and “ppqqrr” are “Albumtitle2 = AAAAA-Best Truck2 = 3” and “Albumtitle2 = “AAAA-Best Truck 2 = 5” is recorded (step 25).

  When such ripping is performed, the album reproduction can be performed as follows. Conventionally, a playlist is often created each time an artist or album name is selected by a user, and playback is controlled accordingly. Even when ripping is performed according to the present embodiment, album reproduction can be performed in the same manner. That is, conventionally, when a music file corresponding to the selected album name is extracted and a playlist is created, the music in which the same album name as the selected album name is recorded in the album name column of the tag information Although the file is extracted, the second album name and the track number are recorded in the comment field of the tag information according to the process of FIG. 2 described above. A music file in which the same album name as the album name is recorded may also be extracted and added to the playlist. As a result, it is assumed that only one album name is recorded in the album name field, and when the song names are the same but the album names are different, as in the conventional case where the album names are different, they are recorded as separate song files. Even when the second album name is selected, the music file accompanying it can be registered in the playlist and played back.

  The music skip operation is basically the same as the above-described album playback operation. When a playlist is created every time a user selects a category such as artist, album name, and genre, the second album name is recorded by making the comment field in the tag information of the music file a search target. For a music file, if the category for the recorded second album name matches the selected category, it is added to the playlist. Since playback is performed in the order of registration in the playlist, when a skip operation is performed, it is only necessary to skip the playback operation of the corresponding music file and start playback of the next music file. That is, even a music file added to the playlist based on the second album name can be played back in the same manner as in the conventional case after being added to the playlist. Similarly, in the case of random playback, when it is selected in which category random playback is to be performed, a playlist is created with the music file selected for search in the comment field based on that category, and the playlist Since random reproduction is performed in the reproduction, reproduction can be performed without any difference from the conventional reproduction method.

  For example, in the case where the music file stored in the storage unit 20 is as shown in FIG. 3 (c), when it is necessary to add the music included in the album name “AAAAA-Best” to various playlists, The album name field in the tag information in the music file is searched, and the music files “GGGGGG.mp3”, “DDDDD.mp3”, and “rararr.mp3” are added to the playlist, and the tag information in each music file The comment field is searched, and the music files “AABBCC.mp3” and “ppqqrr.mp3” are also added to the playlist. However, for example, when a playlist is created in the category of artist “AAAA”, “AABBCC.mp3” and “ppqqrr.mp3” are duplicated and registered in the playlist by making the comment field a search target. Therefore, in this case, the music file that has already been registered in the playlist may not be registered, and duplicate registration in the playlist may be eliminated.

  When a list of song names is displayed, the song names recorded in the song name column in the tag information of each song file may be displayed as a list as in the conventional case. However, when an album name is selected and a song name is listed as belonging to it, the comment field is also searched as shown below, and if applicable, the song name is also listed. Is done.

  FIG. 4 shows an example of a display screen on the display unit 19 when the selected album is reproduced. The figure shows a display screen when the album “AAAAA-Best” is selected when the music file stored in the storage unit 20 is as shown in FIG. In this case, “GGGGGG”, “DDDDD”, and “rararr” are displayed in a list based on the search in the album name column, the comment column is also searched, and the song names “AABBCC” and “ppqqrr” are also listed. The display order is determined based on the track number recorded in the track number column and the track number recorded in the comment column.

  According to the present embodiment, when ripping a CD, the music data of the CD having the same song name as that associated with the music file already existing in the memory unit 20 is not ripped, but instead of the existing music file. Since the album name and track number of the music data are recorded in the comment field in the tag information, the storage capacity in the storage unit 20 can be saved. In addition, when displaying a list of song names, by displaying the song name in the song name column in the tag information of each song file, the same song name is not displayed twice, so that it is easy to view, Selection can be facilitated. In addition, since there are no duplicate music files with the same music title, management of the music files becomes easy.

  FIG. 5 is a flowchart showing another example of the ripping process in the apparatus of FIG. This processing is performed by the CPU 11 according to a predetermined program. In the ripping process of FIG. 2, the result of comparing the album information with the tag information of the existing music file is stored for all the music on the CD, and the existing same music title is not ripped without ripping music with the same music title. The second album name and the second track number are assigned to the music file (step 25). In the ripping process of FIG. 5, the tag information of the existing music file for each song in the CD. Thus, the second album name and the second track number are assigned to the existing music file having the same music title without ripping the music having the same music title.

  That is, when the process is started, first, in step 51, the TOC of the CD loaded in the CD section 13 is read. Next, in step 52, album information about the CD is acquired from a CDDB provided in a server on the external network or the storage unit 20 based on information such as the number of songs in the TOC and performance time. The album information includes information such as the album name of the CD, the name of the music included in the CD, and the artist associated with the album.

  Next, in step 53, "1" is set to the counter N, and the counter N is initialized. The value of the counter N corresponds to the track number on the CD. Next, in step 54, it is determined whether or not a music file having the same music name as the Nth music in the music information column of the tag information already exists in the storage unit 20. If it is determined that it does not exist, the music data of the Nth song is ripped in step 55 and the process proceeds to step 58. At that time, in the tag information of the music file generated by ripping, information such as the album name, the Nth music name, the track number, and the artist is recorded based on the album information.

  If it is determined in step 54 that the corresponding music file exists, the process proceeds to step 56 to check whether the album name recorded in the album name column of the tag information of the music file is the same as that of the album information. Determine. If it is determined that they are not the same, in step 57, the album name of the album information and the track number of the Nth song are recorded as the second album name and the second track number in the comment field in the tag information of the music file. Then, the process proceeds to step 58. If it is determined that they are the same, the Nth music already exists in the same album, and there is a music file with the same music title, so the process directly proceeds to step 58 without performing any processing.

  In step 58, it is determined whether or not the Nth song is the last song on the CD. If it is determined that the Nth song is not the last song, the counter N is incremented in step 59 and the process returns to step 54 to perform the same processing for the next song. I do. If it is determined that the song is the final song, in step 60, information such as the album name and each song name in the album information is registered in a predetermined database, and the ripping process in FIG. This database is for registering and managing each album stored in the storage unit 20 and music belonging to each album in association with each other.

  According to this ripping process, when the music file previously generated by ripping or the added second album name or the like has not been individually deleted after that, the case of the ripping process of FIG. The result is the same. On the other hand, according to the ripping process of FIG. 2, if music files having the same music name exist and the album names are the same, neither ripping nor addition of the second album name or the like is performed. On the other hand, according to the ripping process of FIG. 5, it is determined whether to rip or add a second album name or the like for each CD track (steps 54 and 56). ) Even if there is a music file with the same song name associated with the same album name as the CD, it is deleted if the other music file or the second album name etc. relating to the album name are individually deleted. The music file, the second album name, etc. are replenished again (steps 55 and 57). Instead of processing all track numbers N included in the CD, ripping or the like may be performed in the same manner only for the track number N instructed by the user.

  FIG. 6 is a diagram for explaining a database used in another ripping process by the apparatus of FIG. In the ripping process of FIGS. 2 and 5, the second album name and the second track number are recorded in the comment field of the tag information. In the ripping process according to FIG. Instead, the second album name and track number are recorded in a database for managing music files.

  That is, in a conventional audio device, DAP, music transfer application program, and the like, in many cases, a music file is managed by constructing a database as shown in FIG. Each record in this database is entered for each music file, and includes items such as “file name”, “song name”, “album track number”, “artist”, “genre”, and the like.

  Therefore, in the ripping process according to FIG. 6, this database is used, and the item name of the existing “album track No.” is set to “album 1 track No.” as shown in FIG. Add “Track No.” item. Then, the second album name and the second track number that were recorded in the comment field in the tag information in the processing of FIGS. 2 and 5 are recorded as the items of “album 2 track No.”. Yes. The contents of the other processes are the same as those in FIGS. 2 and 5 except that information registered in the database is used instead of the tag information. That is, the CPU 11 performs ripping by performing processing in the same manner as in FIGS. 2 and 5 for the records in the database corresponding to each music file instead of the tag information of each music file. Can do. In this case, different album names can be set for one music file as in the case of FIGS.

  When the music file is transferred by using the database of FIG. 6C, the music file of the same music and the music related to a different album exists at the transfer destination, instead of transferring the music file. In the record of the transfer destination music file, the album name and track number are recorded as items of “Album 2 Track No.”, so that the processing and time for transfer are omitted, and the storage capacity at the transfer destination is reduced. Can be saved.

  That is, the audio device refers to the storage contents of the mass storage device in the DAP or the like connected via the connected interface unit 22, and constructs the database of FIG. 6C for the music files stored therein. Then, it is copied in a mass storage device such as DAP. When transferring music files to DAP, etc., it is determined whether or not there is a music file that has the same music as the music file to be transferred but has a different album by searching the copied database. In this case, as in the case of steps 25 and 57 in FIG. 2 and FIG. 5, the music file is not transferred, but instead the item “album 2 track No.” in the record of the existing music file is used. Record the album name and track number of the music file scheduled to be transferred. The album name and track number to be recorded can be obtained by referring to a similar database in the audio device.

  For example, it is assumed that the DAP has a copy of a database having contents as shown in FIG. 6C constructed by the audio device for music files stored in the DAP connected to the audio device. However, it is assumed that nothing is recorded in the item “album 2 track No.” in the record whose file name is “f1.mp3”. In this state, the music file “F5.mp3” having the song name “aaa”, the album name “SSS”, the track number “7”, and the artist “D” as shown in FIG. The CPU 11 is based on the fact that the song name “aaa” and the artist “D” in the record whose file name is “f1.mp3” in the database in the DAP are the same as those of the song file to be transferred. It is determined that the music of the music file to be transferred is the same as the music of the music file corresponding to the record in the database. The content of “Album 1 Track No.” in the record is “AA 1”, which is different from the album name “SSS” of the music file to be transferred. In this case, the CPU 11 does not transfer the music file, but instead records the album name and track number of the music file to be transferred as the item “Album 2 Track No.” in the record. In this way, even when the music file is transferred to the DAP, unnecessary data transfer can be avoided and the storage capacity of the DAP can be saved.

  Note that the present invention is not limited to the above-described embodiment, and can be appropriately modified and implemented. For example, in the ripping process shown in FIGS. 2 and 5, the MP3 format music file is used, and the second album name and the second track number are recorded in the comment field of the ID3 tag. In the case where other music file formats are used, similarly, the second album name and the second track number can be recorded in a remarks column not used in the metadata.
