Description

  The present invention relates to an information processing apparatus, an information processing method, and a computer program. In particular, in more detail, for example, efficient information acquisition is performed by selectively using an information providing service for attribute information such as song names and artist names corresponding to music contents made up of analog sound sources such as records and cassette tapes. The present invention relates to an information processing apparatus, an information processing method, and a computer program.

  Content recorded by analog data such as a record player / cassette tape can be converted into digital data via a PC or the like, and recorded as digital data on a hard disk, CD, DVD, or the like.

  Usually, these data recording processing programs have a function of automatically detecting the interval between songs based on the silent portion of continuous recorded data and dividing the song. A silent data area for a certain time is set between each piece of music and recording is performed on a recording medium such as a hard disk or a CD-R.

  In a commercially available CD album or the like in which a plurality of music data is stored as digital data, information such as the number of tracks recorded on the CD, the start position, and the length of the data area of each song is recorded in advance as index information. Yes. This is generally called TOC (Table Of Contents) information.

  As one of information providing services via the Internet or the like, there is a song information providing service based on TOC (Table Of Contents) information. This is a service that provides tune information stored in a CD corresponding to the TOC, such as title, album name, artist name, track number, etc., by transmitting the TOC information recorded on the CD to the information providing server. is there.

  Many jukebox applications, such as Windows Media Player, RealOne, and SonicStage, provide information provision processing services using TOC information services such as CDDB2.

  Furthermore, instead of the TOC consisting of a plurality of pieces of music information, one side of the music piece, that is, the hash data is generated from the waveform data of each piece of music data, and the generated hash data is transmitted to the information providing server, so that the server side There is a hash information service as a service for specifying a song based on hash data and providing a title, album name, artist name, track number, etc. as song information.

  An application such as SonicStage Mastering Studio 1.1 provides information provision processing using a hash information service. SonicStage Mastering Studio 1.1 uses a service provided by MoodLogic as a hash information service.

  These TOC services and hash information services are basically information providing services for recording data based on digital data. For example, Patent Document 1 discloses an example of a conventional technique that discloses a system for downloading music information using TOC information.

  When content recorded as analog data, such as a record player or cassette tape, is converted to digital data via a PC or the like and recorded on a hard disk or the like as digital data, the source (sound source) is, for example, an old record board In some cases, the sound source may contain a lot of crackle noise (sounds like petit petits). In such a case, in order to receive the hash information service, it was recorded on a CD-R or the like according to the program providing the hash information service. When a hash value based on data is calculated, a hash value that is the same as the hash value of the original digital content may not be generated due to noise of the analog sound source. Even if this hash data is transmitted to the information providing server, there is a problem that an accurate data search is not executed and correct song information cannot be obtained.

The hash information service provides an information acquisition / submission (registration process) service in units of music. For this reason, when recording through one analog record, there is no guarantee that all songs included in the analog record are registered in the hash information service. For this reason, even if song information is acquired through an album, some songs may not hit. In particular, there is a problem that it is difficult to receive all song information from the hash information service in the best compilation albums that collect songs from other albums.

Is used to complete the aforementioned music list (see FIG. 5).

  The project management unit 113 completes the project file 121 by describing necessary data in the project file 121 (see FIG. 3) based on the completed song list.

  The song list 123 is a temporary data file. The data storage unit 120 finally corresponds to a recorded data file 122 (WAV file) that is a data file of a recorded song and a recorded data file 122. The project file 121 is saved as XML description data that is attribute information.

  The hash information service providing server 172 is a server that provides a search service for music information existing on the Internet or the like. The music information is searched using a hash value calculated based on the waveform data of the music as a search key, and information such as the title, album name, track number, and artist name of the music is provided. The hash information is a hash value calculated by applying a specific hash generation algorithm with the waveform data of the music as an input. The hash algorithm is represented by binary data of several hundred bytes to several thousand bytes, for example.

  The TOC information service providing server 171 is a server that provides a search service for album information existing on the Internet or the like. Album information can be searched using TOC information such as album CD as a search key, and information such as the title and artist name of each song included in the album can be acquired.

  The information processing apparatus (PC) 100 of the present invention generates TOC information or hash information corresponding to the recording data, and transmits the generated information to the TOC information service providing server 171 or the hash information service providing server 172 to transmit the song information. Execute the acquisition process.

  The TOC information is basically information set in correspondence with an album CD storing a plurality of songs and recorded on the CD. The recorded song and the length of each song (number of CD frames) are set. It contains coded data and can be expressed with very short text data.

A specific example of TOC information is shown below.
[150 29343 52049 73471 92322 98519 119236 135071 158318 175367]

The TOC information is
Number of frames for the first song: 150
Number of frames in second song: 29343
Number of frames in the third song: 52049
Less than,
Number of frames in the 10th song: 175367
The number of frames of each song up to is recorded.

  The number of frames is data corresponding to the performance time. Even when analog records are to be recorded, the same work may be released as a CD. In such a case, if the number of songs and the length of each song are known, the TOC information service is used to record the album. Song information can be acquired. However, the recognition rate of the TOC information service decreases when the dividing points of the music are not correctly input.

  Hereinafter, a plurality of aspects of the music information acquisition processing sequence corresponding to the recording processing data executed in the information processing apparatus of the present invention will be described in sequence. Note that the recording process and song information acquisition process described below are processes executed in the data processing unit 110 (see FIG. 2) of the information processing apparatus in accordance with a program describing a processing sequence shown in each flowchart.

(1) Process example including process for determining whether or not recording process target is album First, a flowchart shown in FIG. 6 is shown for a recording and song information acquisition process example including a process for determining whether or not the recording process target is an album. The description will be given with reference.

  In step S101, a reproduction music of an analog sound source such as an analog record is input and a recording process is executed. The recording data file 122 shown in FIG. 2 is generated by the recording process. In parallel with this recording process, a song list 123 is generated. As described above with reference to FIG. 5, the song list includes the hash value (Hash) of each song, the song No. (#), Title name (Title), artist name (Artist), album name (Album), performance time (Duration), etc., each item constituting the attribute information corresponding to the song is included. Song information such as name (Title), artist name (Artist), and album name (Album) has not been acquired, and only the hash value (Hash) and performance time (Duration) in the setting items of the song list shown in FIG. However, it can be set in parallel with the recording process.

  The recording data management unit 114 acquires these pieces of information in parallel with the recording process and sets them in the song list. By this process, the music list shown in FIG. 7A is set.

  As shown in FIG. 7A, only the hash value (Hash) and performance time (Duration) of each song are recorded in the song list. With respect to each of these values, the inter-song detecting unit 116 determines that the silent time that is equal to or less than a predetermined threshold is inter-song, determines the data portion sandwiched between the songs as one music, and plays time (Duration) Is calculated, and the hash value calculated by a predetermined hash value calculation algorithm is recorded based on the waveform data within the performance time (Duration).

  However, since the inter-speech detection unit 116 automatically performs a process of determining a certain silent time as inter-speech, for example, processing time when moving from the front of the record to the back or a record needle is dropped on the board. In some cases, the time from the beginning to the beginning of the first song, or a certain period of silence after the end of the last song is determined as the interval between songs.

  In step S102 in the flow shown in FIG. 6, deletion of these unnecessary segments is executed. This unnecessary segment deletion process can be executed as a process of deleting a song list shown in FIG. 7A on the display and the user determining that the song is not a song. Alternatively, the recording data management unit 115 may automatically execute an entry in which a performance time (Duration) within a predetermined threshold time is set.

  As a result of this unnecessary segment deletion, the entries e1 to e6 are determined as unnecessary segments from the music list shown in FIG. 7A and deleted, and as a result, the music list shown in FIG. 7B is generated.

  In step S103, a data sound source type indicating whether or not the recorded music data is data from an album storing a plurality of songs is determined. This determination process is executed based on information input via the GUI 111 by the user (operator) executing the recording process, or a plurality of songs are continuously recorded in the recording data management unit 115 of the information processing apparatus. When it is input, or when it is a data file including a plurality of songs, the recorded content may be determined as an album.

  When it is determined that the recorded content is an album (step S104: Yes), in step S105, the recording data management unit 115 or the TOC information search unit 118 determines the TOC based on the song list (see FIG. 7B). Information is generated and transmitted from the TOC information search unit 118 to the TOC information service providing server 171.

  The TOC information is generated based on performance time (Duration) data set in the song list (see FIG. 7B). The performance time (Duration) set in the song list (see FIG. 7B) describes the performance time of each song as time data of n minutes and milliseconds.

  The TOC information transmitted to the TOC information service providing server 171 is set as information obtained by sequentially arranging the performance time information. The TOC information transmitted to the TOC information service providing server 171 is performance time data for each song or frame number data for each song. The number of frames can be calculated from the performance time (seconds) based on the number of frames per second (for example, 75 frames / second).

The TOC information to be generated is, for example, the following data:
[150 29343 52049 73471 92322 98519 119236 135071 158318 175367]
It is. The TOC information search unit 118 transmits the generated TOC information to the TOC information service providing server 171.

  Based on the received TOC information, the TOC information service providing server 171 performs a collation process with the TOC information registered in the database of the server, and the song information (title name of each song, The artist name, album name, etc.) are acquired, and the acquired information is transmitted as a response to the information processing apparatus 100.

  In step S <b> 106, the information processing apparatus receives song information from the TOC information service providing server 171. In step S109, the song list is updated based on the song information received from the TOC information service providing server 171. That is, a process of writing the title name, artist name, album name, etc. of each song received from the TOC information service providing server 171 to the song list is performed. By this process, the completed music list shown in FIG. 5 is generated.

When the song list is completed, in step S110, a project file 121 (see FIG. 3) is generated based on the song list. As mentioned above, the project file is
Reference information to recording data file Position information of song division point Information such as title, artist name, performance time of each song,
Is stored in the data storage unit 120 as an attribute information data file of a recording data file.

  Through the above processing, the recording data file 122 and the project file 121 are stored in the data storage unit 120 of the information processing apparatus 100 shown in FIG.

  If it is determined in step S104 that the sound source is not an album (step S104: No), song information acquisition processing based on TOC information cannot be performed. This is because the TOC information is an album recorded music information providing service based on performance time data of a plurality of songs corresponding to the album.

  In this case, the song information is acquired in units of songs using a hash information service based on the hash value for each recorded song.

  In step S107, the hash value of each song set in the song list (see FIG. 7B) is acquired, and the acquired hash value is transmitted to the hash information service providing server 172 via the hash information search unit 117. .

  The hash information service providing server 172 searches for music information using the received hash value as a search key, acquires information such as the title, album name, track number, and artist name of the music, and provides the information to the information processing apparatus.

  In step S <b> 108, the information processing apparatus receives song information from the hash information service providing server 172. In step S109, the song list is updated based on the song information received from the hash information service providing server 172. That is, a process of writing the title name, artist name, album name, etc. of each song received from the hash information service providing server 172 to the song list is performed. By this process, the completed music list shown in FIG. 5 is generated.

  When the song list is completed, in step S110, a project file 121 (see FIG. 3) is generated based on the song list.

  Through the above processing, the recording data file 122 and the project file 121 are stored in the data storage unit 120 of the information processing apparatus 100 shown in FIG.

  As described above, in the information processing apparatus of the present invention, when the sound source to be recorded is an album, the tune information acquisition process is executed, and when the sound source to be recorded is not an album, the hash information is obtained. Since the applied music information acquisition process is executed, accurate music information acquisition and project file generation are possible regardless of the type of sound source.

  In particular, in the present processing example, it is determined whether or not the sound source is an album, and the TOC information service or the hash information service is selected. The music information can be efficiently acquired with the Internet connection time.

  For example, when a CD sound source recorded on a cassette tape is applied as a sound source for PC recording, it is possible to relatively accurately obtain information on the duration of each song and performance time. Is a process suitable for such sound source recording processing, music information acquisition, and the like.

(2) Application of Hash Information Service after Application of TOC Information Service Next, a processing sequence for applying the hash information service after application of the TOC information service will be described with reference to the flowchart shown in FIG.

  In step S201, a reproduction music piece of an analog sound source such as an analog record is input, and a recording process is executed. The recording data file 122 shown in FIG. 2 is generated by the recording process. In parallel with this recording process, a song list 123 is generated. The generated music list is a list in which only the hash value (Hash) and performance time (Duration) of each music are recorded, as shown in FIG. In step S202, unnecessary segment deletion is executed from the song list, and the song list shown in FIG. 7B is generated.

  In step S203, TOC information is generated based on the song list (see FIG. 7B), and the generated TOC information is transmitted to the TOC information service providing server 171 via the TOC information search unit 118.

  The TOC information is generated based on performance time (Duration) data set in the song list (see FIG. 7B). The performance time (Duration) set in the song list (see FIG. 7B) describes the performance time of each song as time data of n minutes and milliseconds.

  The TOC information transmitted to the TOC information service providing server 171 is set as information obtained by sequentially arranging the performance time information. The TOC information transmitted to the TOC information service providing server 171 is performance time data for each song or frame number data for each song. The number of frames can be calculated from the performance time (seconds) based on the number of frames per second (for example, 75 frames / second).

The TOC information to be generated is, for example, the following data:
[150 29343 52049 73471 92322 98519 119236 135071 158318 175367]
It is. The TOC information search unit 118 transmits the generated TOC information to the TOC information service providing server 171.

  Based on the received TOC information, the TOC information service providing server 171 performs a collation process with the TOC information registered in the database of the server, and the song information (title name of each song, The artist name, album name, etc.) are acquired, and the acquired information is transmitted as a response to the information processing apparatus 100.

  In step S <b> 204, the information processing apparatus receives song information from the TOC information service providing server 171. In step S205, the song list is updated based on the song information received from the TOC information service providing server 171. That is, a process of writing the title name, artist name, album name, etc. of each song received from the TOC information service providing server 171 to the song list is performed.

  In step S206, it is determined whether or not the song list is completed by updating the song list in step S205, that is, whether or not the song information of all the songs has been acquired. When the song list is completed (step S206: Yes), a project file (see FIG. 3) is generated based on the song list and stored in the data storage unit 120 in step S210.

  If it is determined in step S206 that the song list has not been completed by updating the song list in step S205, that is, data for which song information has not been acquired remains and the song list is incomplete (step S206: No) goes to step S207 and acquires unacquired song information using a hash information service.

  In step S207, a hash value corresponding to unacquired song information set in the incomplete song list is acquired and transmitted to the hash information service providing server 172 via the hash information search unit 117.

  The hash information service providing server 172 searches for music information using the received hash value as a search key, acquires information such as the title, album name, track number, and artist name of the music, and provides the information to the information processing apparatus.

  In step S <b> 208, the information processing apparatus receives song information from the hash information service providing server 172. In step S209, based on the song information received from the hash information service providing server 172, the song information that could not be acquired by the TOC information service is written in the song list and the song list is updated. By this process, the completed music list shown in FIG. 5 is generated.

  When the song list is completed, in step S210, a project file 121 (see FIG. 3) is generated based on the song list.

  Through the above processing, the recording data file 122 and the project file 121 are stored in the data storage unit 120 of the information processing apparatus 100 shown in FIG.

  In this processing example, first, music information acquisition processing based on TOC information is executed, and thereafter, unacquired music information is complementarily acquired by a hash information service. When the analog record is a sound source, the music division process may not be performed correctly due to the influence of the sound of the music. In such a case, the TOC information service alone fails to acquire all the music information. There is a case. In such a case, by using the hash information service in a complementary manner as in this processing example, it is possible to increase the success rate of obtaining the music information.

(3) Execute the hash information service, determine whether the sound source is an album, and apply the TOC information service based on the determination result. Next, as a third processing example, first, execute the hash information service to obtain An example of a processing sequence for determining whether a sound source is an album based on information and applying a TOC information service based on the determination result will be described with reference to a flowchart shown in FIG.

  In step S301, a reproduction music of an analog sound source such as an analog record is input, and a recording process is executed. The recording data file 122 shown in FIG. 2 is generated by the recording process. In parallel with this recording process, a song list 123 is generated. The generated music list is a list in which only the hash value (Hash) and performance time (Duration) of each music are recorded, as shown in FIG. In step S302, unnecessary segment deletion is executed from the song list, and the song list shown in FIG. 7B is generated.

  In step S303, the hash value of each song set in the song list (see FIG. 7B) is acquired, and the acquired hash value is transmitted to the hash information service providing server 172 via the hash information search unit 117. .

  The hash information service providing server 172 searches for music information using the received hash value as a search key, acquires information such as the title, album name, track number, and artist name of the music, and provides the information to the information processing apparatus.

  In step S <b> 304, the information processing apparatus receives song information from the hash information service providing server 172. In step S305, the song list is updated based on the song information received from the hash information service providing server 172. That is, a process of writing the title name, artist name, album name, etc. of each song received from the hash information service providing server 172 to the song list is performed.

  In step S306, it is determined whether or not the song list is completed by updating the song list in step S305, that is, whether or not the song information of all the songs has been acquired. When the song list is completed (step S306: Yes), a project file (see FIG. 3) is generated based on the song list and stored in the data storage unit 120 in step S313.

  If it is determined in step S306 that the song list is not completed, that is, data for which song information has not been acquired remains and the song list is not completed (step S306: No), the process proceeds to step S307. Based on the acquired music information, it is determined whether or not the sound source is a song recorded in the same album.

  For example, it is assumed that the music list is updated as shown in FIG. 10 by applying the hash information service.

  The song list shown in FIG. The pieces of music information 1 to 6 and 8 to 9 are acquired from the hash information service providing server 172 by the hash information service. 7 shows an example in which only the music information 301 of 7 cannot be acquired.

  In such a case, it is determined whether or not the album name information included in the acquired music information is the same album. In the case of the example shown in FIG. The album names acquired as the pieces of music information 1 to 6 and 8 to 9 are all “Hotel California”.

  If it is determined in step S307 that all the acquired song information is the same album, the process proceeds to step S308, and a song information acquisition process based on the TOC information is executed. If it is not determined that all of the acquired song information is the same album, it is determined that the probability of successful information acquisition is small even if the information acquisition processing based on the TOC information is executed, and the process proceeds to step S313, where Generate a project file with only the information acquired by the information, store it, and finish the process.

  In step S307, if it is determined that all the acquired song information is the same album, it is determined that there is a high probability that unacquired song information is acquired by the song information acquisition process based on the TOC information. Proceeding to step S308, TOC information is generated based on the song list (see FIG. 7B), and the generated TOC information is transmitted to the TOC information service providing server 171 via the TOC information search unit 118.

The TOC information to be generated is, for example, the following data:
[150 29343 52049 73471 92322 98519 119236 135071 158318 175367]
It is. The TOC information search unit 118 transmits the generated TOC information to the TOC information service providing server 171.

  Based on the received TOC information, the TOC information service providing server 171 performs a collation process with the TOC information registered in the database of the server, and the song information corresponding to the matching registered TOC information (the title name of each song, The artist name, album name, etc.) are acquired, and the acquired information is transmitted as a response to the information processing apparatus 100.

  An example of music information transmitted by the TOC information service providing server 171 is shown in FIG. In FIG. 11, song information of songs recorded in the album “Hotel California” is set as a list. 7 song information 302 is also included.

  In step S309, the information processing apparatus receives song information from the TOC information service providing server 171. In step S310, music information has been successfully received from the TOC information service providing server 171. That is, for example, when the information shown in FIG. 11 can be acquired, the music list is updated based on the acquired information in step S311. .

  In step S312, the hash information is transmitted to the hash information service providing server 172, and registration processing is performed. By this registration processing, a hash value based on the recorded sound source data is set as a registered hash value in the database of the hash information service providing server 172.

  When the music information that could not be acquired only by the hash information is acquired by the TOC information service, as shown in FIG. 12, the entry (No. 7) of the music information that could not be acquired only by the hash information shown in FIG. Complemented by the song information 303 acquired by the information service, the song list is completed.

  In step S313, the project file 121 (see FIG. 3) is generated based on the completed song list updated in step S311, and stored in the data storage unit 120.

  If it is determined in step S310 that the music information has not been successfully received from the TOC information service providing server 171, a project file is generated with only the information obtained from the hash information in step S313, stored, and the process ends. .

  In this processing example, first, song information for each song is acquired by the hash information service, and it is determined whether the sound source is an album based on the acquired information, and the TOC information service is applied based on the determination result. This is a sequence for acquiring song information that could not be acquired by the hash information service.

  When the sound source is an analog record, a hash value different from the correct hash value may be calculated due to the influence of noise or the like, and all pieces of music information may not be obtained only with the hash information service. In such a case, as in this processing example, by using the TOC information service in a complementary manner, it is possible to increase the possibility of acquiring all pieces of music information. Also, by executing hash value registration processing together, it is possible to update the database of the hash information service providing server, and this update processing can improve the recognition rate of the hash information service.
