The present invention relates to a method and system for constructing a database including sound source sample files and providing sound source samples over a network, and more particularly to include sound source samples generated by decomposition of instrumental and segmental data from existing music. A method and system are provided for establishing a database and providing these sound source samples to a user through a network so that the user can compose music in a convenient way.

Recently, with the development of computer technology and internet technology, a number of systems capable of composing music using cyber space have been disclosed. As an example, Korean Patent Laid-Open Publication No. 2000-0058995 discloses a program that installs a program through the Internet / private line, composes / arranges a score, receives a music appreciation, record purchase, and personalized information service through the Internet / private line, and reflects / votes preferences. A subscriber system including a user, a singer who selects songs through the Internet / private line, a singer who registers songs, a record company / producer who discovers a composer / singer and produces a record through the Internet / private line, an ASP server connected to the Internet / private line, Web server, stream server and sound source server, music management system, music score management system, automatic arrangement system, music preference analysis system, order management system, copyright analysis system, cyber audition system, copyright registration system which are interconnected to each server Web is configured to provide a database by connecting various DB to the system It using disclosed about the music composition system and method.

In addition, Korean Patent Laid-Open Publication No. 2005-0005265 is a composition system for generating electronic music through an application service program (ASP), which is computer composition software, and provides a computer composition software service and a web server having a database storing a plurality of composition and composition data. And a user system connected to the web server through a public network, wherein the user system includes cut means for cutting a predetermined node for each of a plurality of pieces of composition and song data stored in the database, and a predetermined cut cut by the cut means. Disclosed is a composition system and method using software comprising a paste means for editing and pasting a node of a word and processing means for processing the rhythm, melody, session, and effect sound of the sheet music edited by the paste means.

However, according to the aforementioned Patent Publication No. 2000-0058995, the composition and song data stored in the sound source bank are stored in the unit of one original song, and the composition system adds a bit change, a genre change, and an effect sound for the whole original song. Since only the function of composer can be performed, the composition or arrangement of the composition is extremely limited when the user performs the composition or arrangement, and the service for the composer online or downloaded for the PC Since the music input program is used to input the music scores, after modifying the music, the music is modified by listening to the music using the module instrument provided by the ASP as the arrangement function, and downloading the sound source from the music bank again after composing or arranging the music. Since the composed or arranged music is played only after receiving it, There is a problem that it is inconvenient for the Korean public to use the composition to perform the composition or arrangement.

In addition, in the above-described Patent Publication No. 2005-0005265, a cut and paste method of generating music scores by selecting a plurality of song names desired by a user from songs, songs, etc. stored in a database, and manipulating them to be displayed on a display on the output unit is desired. As a result, only each section of the original song including all the instruments and voices is subject to editing, and thus, the composition or arrangement of the respective instruments and nodes cannot be performed and the range of the composition or arrangement is extremely limited.

The present invention is to solve the above-described problems of the prior art, so that even a general person outside of the composition can compose or arrange the composition in a convenient manner without limiting the range of the composition or arrangement is almost already existing Build a database containing sound source samples, which are the minimum nodes for each instrument that is used more than once in music, and manage the sound source samples to compose or arrange new music using the network and sound source samples built into the database. To provide a method and a system for that purpose.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before examining a method for constructing a database including sound source sample files according to the present invention, a composition principle when the composer of modern music composes music is described.

Modern music, such as pop songs, is often a single song, with several rhythms and melodies repeated over and over again. Especially in the case of dance music such as hip hop or techno, one or two short sound source samples are repeated in succession to form a single song. As used herein, a sound source sample (hereinafter, also referred to as “instrumental pattern element”) refers to a minimum measure for each musical instrument that is used more than once in a certain music. In other words, it refers to the smallest unit of a repeating pattern when music is classified by the instrument used in the music. For example, a song used only two instruments, a drum and a bass, and the drum was then beat again (A), thumping thump (B), thumping thump (A), thumping thump (C) If you repeat the bass again and again and again (D), floats (E), floats (D), floats (F), this song is A, It can be said that it consists of the drum pattern elements of B and C, and the base pattern elements of C, D, and E. These sound source samples, i.e., instrumental pattern elements, are often audio samples generated by one instrument and, in some cases, may be synthetic audio samples or speech samples of several instruments. In addition, modern pop songs as described above may also be configured to include a track consisting of a single instrumental pattern element that is sometimes repeated several times throughout the duration of the music, containing a single instrumental pattern element on a sample CD. It is also sold on the market.

When composers of modern music compose music, the melody of the music is composed directly, and the drum beats, bass, and other electronic syntheses and effects of the music are recorded on the commercially available sample CD as described above (loop). ) Is common. Such a sample CD is produced by the maker of the CD, a sample of each instrument, a sample consisting of a combination of instruments, and a sample of the effect sound on a CD, and the producers sell the samples when the samples are sold. All rights are paid in the form of paying all the royalties for the company, selling it for a certain amount, or selling it for a certain period of time.

Composers make music by modifying the sound source sample contained in the sample CD as it is or after partially modifying it and inserting it in necessary parts. Therefore, a certain portion of a number of songs can be made based on the sound source samples contained in the sample CD, and the entire music can be made only with the sound source samples of the sample CD.

The present invention breaks down modern music such as popular pop songs made in the manner described above into sound source samples, that is, the components thereof so as not to overlap for each instrument or effect sound from the existing music which has already been composed. Create sound samples by disassembling them into samples, build them into databases, and provide them to users through a network so that users can use them to easily compose and / or arrange existing or new music. It is characterized by.

Hereinafter, an overall configuration of a sound source sample file providing system according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 3. The sound source sample file providing system of the present invention includes a service database 31 in which sound source sample files are constructed as described in detail below, and a service server 32 that manages these sound source sample files and provides them to a user through a network such as online. It includes. In addition, the sound source sample providing system of the present invention comprises a user client 33 for downloading sound source samples from the service database 31 and a user sound source database 34 in which the downloaded sound source sample files are stored through a network such as online. Include.

As shown in Fig. 2, the service database 31 includes a member database 41 containing information on members who have subscribed to the service, a sound source sample database 42, and a user sound source registration history database 43. Included. The sound source sample database 42 includes a free sound source sample file which is provided by the service provider and is provided for the user to download free of charge without compromising with the copyright, and a user-produced sound source sample file that the user has made and registered in the service database. And purchases that are disassembled from music composed by a particular composer so that they do not overlap with each instrument and each bar, and licensed under the condition that the composer is licensed or the user pays a certain fee for the sound source sample. Sound source sample files are included. In this case, any payment method may be used, such as electronic payment by credit card, electronic payment by electronic money such as coin, or electronic payment using accumulated points.

In addition, the user sound source registration history database 43 includes information on the user himself produced and registered in the case of the user-produced sound source sample file for each user, and the sound source sample file or the purchased sound source sample file produced by another user. In this case, user registration and purchase history information including information indicating whether users have purchased or registered the sound source sample is stored.

In addition, the service server 32 of the present invention refers to the member database 41, the member login check module 44, the user sound source database 34 to check whether the user logged in through the client program is subscribed to the service The latest version check module 45 for checking and updating the latest version of the free sound source sample files in the file, and for the user-created sound source sample files, confirms that the sound source sample file is created and registered by the logged-in user, and purchases the sound source sample file. For example, the available sound source database check module 46 for checking whether a logged-in user has purchased and registered the purchase sound source sample file, and the other client request processing module 47 for responding to other user requests. It includes.

On the other hand, in the user client 33, as shown in FIG. 3, an input module 51 used to input sound source samples in the user sound source database 34 into the client program, and a display for displaying the input sound source samples on the display. A module 52, an execution module 53 for reproducing respective sound source samples, reproducing music before completion while the sound source samples are input, or reproducing completed music after all desired sound source samples are input, the service database ( 31, a purchase module 54 for purchasing, downloading, registering, and the like of the sound source sample files from the user sound source database 34. In addition, the user sound source database 34 includes a free download sound source database 55 that stores free sound sample files downloaded free from a service provider, and is purchased from a service provider and registered by the service provider, and is downloaded from the service database 31. A purchased sound source database 57 in which the received purchase sound source sample files are stored, and a registered sound source database 57 in which the user-produced sound source sample files, which are produced by the user and registered with the user's information in the service database 31, are stored. .

4 is a diagram schematically showing the configuration of a sound source sample file 61 according to an embodiment of the present invention. The sound source sample file 61 is composed of a header portion 65 and a sound source portion 66. In the header portion 65, information on the content of the sound source 64 in the sound source portion 66, that is, the type of musical instrument used for the sound source and the type of genre such as hip hop, techno, ballad, and the like, is stored in the sound source information 62. Is stored encrypted. In the case where the sound source sample is a purchased sound source sample decomposed from an existing song, the sound source information 62 includes information on the original song before decomposition (the name of the original song, the genre, the musical instrument, the position of the sound source sample in the song before decomposition, etc.). Information) may also be stored. In the header portion 65, the information of the service provider in the case of the free sound source sample, the information of the composer of the disassembled original song in the case of the purchase sound source sample file, and the information of the user himself produced in the case of the user-made sound source sample file are shown. Author information 63 is stored encrypted.

In this way, among the sound source sample files registered in the service database, the user downloads free of charge or pays for the fee and registers and downloads them, or the sound source sample files that are manufactured and registered in the service server are stored in the user sound source database 34. Therefore, even if a user purchases a sound recording sample and then personally shares the sound recording sample, for example, through a sharing site, the sound recording sample cannot be used unless the author or purchaser of the sound recording sample is used and the sound recording sample is manipulated. Even attempts can be blocked. That is, even if a specific sound source sample is produced or manipulated, the user who wants to use the sound source sample is allowed to use the sound source sample by causing the author information 43 and the sound source information 42 to be decoded by the service server by the sound source registration process as described below. Since it is possible to check whether the original sound source is not a free download sound source, a purchased sound source, or a sound source produced by oneself, registration itself becomes impossible.

The sound source contents 64 of the purchase sound source sample file described above can be generated by decomposing the already composed existing music, such as a popular song composed in the manner described above, into samples again. That is, the sound source samples for each sample may be generated by decomposing the existing song into samples that are components so that each instrument or effect sound does not overlap for each node. The user can reconstruct the sound source samples built into the database to create the original song, which not only allows the user to understand the compositional principles of the music and to accumulate his musical knowledge, but also to enjoy his / her own music by making his own songs. You may feel it.

For example, let's say you listened to an existing song and analyzed it and found that the song consists of the following samples. The drum consists of three types of beats: A, B, and C. The bass consists of three types of performances: D, E, and F. The piano has the melody of G repeatedly, claps (H), shouts ( I), let's say three kinds of effect sounds of telephone ringing sound (J) are inserted at least once in the middle of a song. In this case, the song can be broken down into a total of 10 components from A to J.

5 is a schematic diagram illustrating a configuration screen of a client program used in the user client 33 to reconstruct a song that can be decomposed into a total of ten components A to J. FIG. Referring to FIG. 5, as shown in the lower part, a user may compose and / or arrange a free sound source sample file, a purchase sound source sample file, and a user-created sound source sample stored in the user sound source database 34 of FIG. 3. Sound source samples are displayed for each instrument and type of sound source such as drum, bass, piano, and sound effects, for example. Each of the sound source sample files is preferably displayed so that a data entry indicating the type of the bit and the like and the characteristics of the sound source sample appears. The template 500 is configured to insert the sound source samples by a drag and drop method by track and node for each instrument. In addition, while the user composes each sound sample or music, or after completing the composition, the play button 510 for playing and listening to music, the save button 520 for storing the played music, the user is stored in the database The purchase button 530 for purchasing and registering a new sound source sample which is not present from the service provider may be included. The figure is for a simple example of a client program, and as will be apparent to those skilled in the art, other functions for composing and arranging, for example, buttons for adjusting the speed or pitch of each music or sound source sample, etc. Or GUI.

As described above, if the sound source sample files constructed as a database according to the present invention are provided to the user through a network, and the user is reconfigured, the original music can be created. When configuring the original song, the tracks are divided by musical instruments, and each track sample is downloaded from the service server, and each of the instruments is arranged in the arrangement of the original songs. However, simply arranging the same does not make it the same as the original, but each instrument can be made closer to the original by volume, equalizer, sound editing, and mixing between the entire instrument. By replacing parts with other samples or adjusting the speed or pitch of the song, you can create a remake song that is completely different from the original. In addition, a completely new music may be created by a new combination of sound source sample files held in the user sound source database, user-produced sound sources, and purchased sound source sample files decomposed from other original songs. Therefore, in the case of using a database constructed in accordance with the present invention, even a general person who is new to composition can learn and perform a composition or arrangement work without any limitation in its scope.

6 is a flowchart illustrating a specific method of providing and managing the sound source sample files to a user according to an exemplary embodiment of the present invention.

Referring to FIG. 6, in step S601, a user executes a client program and performs a login (step S602). When the user logs in, the service server checks whether the user is registered as a member. If the user is not registered as a member in the member database, the service server transmits a member registration screen to induce member registration, and the user is a member. If registered as, the client program screen for composing music is activated.

Thereafter, the service server checks the latest version of the program of the client currently running and the latest version of the free sound source sample files in the user sound source database (step S603). If the check result is not the latest version, the client program and the free sound source sample files are updated to the latest version (step S605), and then the purchased sound source database and the registered sound source database in the user sound source database are checked to confirm that there are no unregistered sound sources (step S605). S606 and step S607). If there is an unregistered sound source, the user is requested to purchase and register the unregistered sound source (step S610), and if the user does not comply with the purchase and registration request, the user cannot use the unregistered sound source so that the unused sound source cannot be used. The unregistered sound source registration induction or inability processing step (S608) is instructed to the client program (step S611).

Thereafter, when the client program is started in step S612, a program screen as shown in FIG. 5 is displayed, and the music is composed or arranged by arranging music samples by inserting sound source samples for each track for each instrument as described with reference to FIG. 5. After the step (S613), the playback button is clicked (S614). The step of clicking the play button may be for previewing each sound source sample before inserting it into a corresponding track, or may be listening in advance to purchase and register new sound source samples necessary for production from a service server. It may be to listen to music produced so far in order to delete, change, etc. a specific sound source sample along the way.

If the user clicks the play button of the produced music while composing the music or after completing the composition in step S614, a play signal is transmitted to the service server, and the service server once again tries to play in the client program at the moment of playing. The sound source sample files are checked to confirm that there are no unregistered sound source samples (step S615). If there is an unregistered sound source, the user is requested to purchase and register the unregistered sound source sample in a manner similar to step S608, and the unregistered sound source sample file cannot be used when the user does not comply with the purchase and registration request. The client is instructed to perform a non-playback process (step S616). In this way, by verifying that there are no unlisted sound sample files before starting the client program, and again, before playing music during or after production, if there are no unregistered sound samples, the user can check in advance from the shared program or other users. Even if you download it or create it yourself and save it on your computer and you try to use it after starting the client program, you can't play any more music because it won't play.

After the music is played back in step S617, the user can continue the music production work such as composition or arrangement (step S618), and when the user clicks the save button to save during composition or arrangement or after the composition or arrangement is completed ( Step S619), the storage signal of the client program is transmitted to the service server so that the service server checks once again the sound source sample files to be used in the client program before storing to confirm that there are no unregistered sound source samples (step S620). . If there is an unregistered sound source sample, the user is requested to purchase and register the unregistered sound source sample in a manner similar to step S616, and that the unregistered sound source sample file cannot be used when the user does not comply with the purchase and registration request. Instructs the client program not to store (step S621). In this way, even if the user saves the music produced by the user in the last time, the user checks if there are no unregistered sound samples. If the user downloads the music from a shared program or from another user, or saves it on the user's computer and saves it on the user's computer, Even if an attempt is made to store it in the client program, it is prevented from being stored, thereby preventing the use of unregistered sound source samples in subsequent composition work.

As described above, according to the present invention, when the client program is started, when the music is played, and when the composition or arrangement is completed and stored, it is confirmed that there are no unregistered sound source samples to induce the registration of the unregistered sound source samples. A user who does not purchase and register a sound source sample has the effect that the possibility of unauthorized use of the sound source sample file can be blocked effectively and efficiently.

According to the present invention, by constructing a database to include sound source samples generated by disassembling by instrument and measure from existing music which have already been composed, and providing these sound source samples to a user through a network, even a general person who is new to composition can compose or While the range of arrangements is hardly limited, it is possible to realize and perform the principles of composition or arrangement in a simple way. In particular, according to the present invention by reconstructing the existing music by using the musical instrument pattern elements decomposed from the existing music already composed, even if the general public is familiar with the existing music already composed based on that memory By arranging sound samples in a template, and trial and error of playing, listening to, and modifying the arranged samples, it is possible to reconstruct existing music without any difficulty, and through this process, it is possible to realize the composition principle of the song.

In addition, in providing sound source samples according to the present invention through a network, it is possible to use a sound source sample protected by copyright by confirming that there is no unregistered sound source sample at each step and inducing registration of an unregistered sound source sample. It can be blocked at its source and efficiently.
