1 is an overall system diagram of a multi-channel sound source file providing service according to a preferred embodiment of the present invention.

As shown, the present invention provides a user using a multi-channel sound source file or a channel file in the sound source file playback apparatus 100 and the sound source file playback apparatus 100 provided by the user using a communication network such as the Internet or a wireless communication network. It is configured to include a multi-channel sound source providing server 200 for providing a customized sound source file arranged to suit the needs of.

An object of the present invention is to provide a multi-channel sound source file or a customized sound source file produced according to a user's request using a communication network such as an internet wireless communication network.

The service providing method for achieving the object of the present invention is largely classified into a user selection method and a provider selection method.

In the first method, the user selection method, the service provider selects an existing sound source file from the user, allocates one channel file to each specific sound constituting the sound source file, and encodes the data to allow individual control in the user's playback device. A method of providing a multichannel sound source file to a user.

The user can download the multichannel sound source file and perform various operations in his device. The above-described method will be described in detail with reference to the drawings shown in FIGS. 2 to 5.

In the second method, the provider selection method, the service provider selects an existing sound source file from the user, provides information on each channel file constituting the sound source file, and receives a channel configuration type manipulated according to the user's taste from the user. It is a way to provide the user with a customized sound source file encoded. The above-described method will be described in detail with reference to the drawings shown in FIGS. 6 to 9.

2 is a flowchart illustrating a method of reproducing a multi-channel sound source file by a user selection method according to an exemplary embodiment of the present invention.

First, a service provider, that is, a multi-channel sound source file providing server 200 receives a sound source file that a user wants to produce as a multi-channel sound source file among existing sound files produced in mono or stereo from a user who visits a website of a service provider. Steps are performed (S200, S210, S220). In the step of selecting a conventional sound source file produced in mono or stereo, the conventional sound source file has an extension such as * .wav, * .mp3.

The wav extension is a basic format of a music CD produced in mono or stereo, and the mp3 extension represents a reduced compressed format in which a sound source file having a wav extension is modified to be implemented in an mp3 player which is a computer or a playback-only device.

That is, almost all the sound source files in the market have the above extension. Therefore, in order for the multi-channel sound source file providing server 200 to produce a multi-channel sound source file, a step of selecting a desired sound source file from the existing sound source files as described above should be preceded.

After the multi-channel sound source file providing server 200 receives a sound source file from the user, the multi-channel sound source file providing server 200 converts the sound source file into a multi-channel sound source file (S230).

In order to generate the multi-channel sound source file, the multi-channel sound source file providing server 200 extracts a corresponding sound source using spectrum analysis of each selected sound source file, and corrects the sound quality of the extracted portions (S230). .

In the case of extracting the channel file of each corresponding sound source from the existing sound source file, the conventional WAV waveform analysis was not technically meaningful because the extraction was not sophisticated, but the method using the spectrum analysis of the time, frequency band, and energy of the sound source Information such as level (db) can be extracted for more sophisticated analysis.

For example, suppose that one sound source file is selected from a user and each corresponding sound source constituting the sound source file is extracted.

The sound source file includes a rhythm part including a rhythm musical instrument, a melody part including a melody giving musical instrument, and a vocal part storing voice.

In this case, the rhythm musical instrument rhythm unit has a specific pattern of the corresponding sound, the multi-channel sound source file providing server 200 grasps the specific pattern of the corresponding sound and extracts each corresponding sound source. The vocal unit is present in mono in a stereo sound source, and the multi-channel sound source file providing server 200 extracts a mono channel (center channel) present in mono in the stereo sound source, and measures the sound level by measuring the energy level of the corresponding sound. Extract the site. In addition, the multi-channel sound source file providing server 200 extracts a portion other than the extracted “rhythm unit” and the extracted “vocal unit” as a melody unit.

The multi-channel sound source file providing server 200 may apply a method as described above to separate a desired sound source such as a musical instrument, a rhythm, a melody, etc. in addition to vocals and accompaniment.

In addition, the sound source may be initially extracted by recording for each instrument by another method.

The multi-channel sound source file providing server 200 corrects the sound quality of each extracted part. The sound quality correction step may be implemented by removing click noise using a DeEsser, a parametric equalizer, a declicker, a DeNoiser, a mastering DSP, an EQ, a COMP, a limiter, and the like with white noise effects.

The multi-channel sound source file providing server 200 distributes one channel file for each of the corrected extraction parts, establishes a multi-channel, and encodes them (S240, S250).

In the encoding step, a separate channel file including images, lyrics, hidden sounds, etc. intended by a sound source producer is secured in order to secure the flexibility of service aspects of the corresponding sound source with the corresponding sound from which the extracted one channel file is distributed. Assign and encode together.

In the encoding stage, coding is performed to reduce the capacity, compress, and have various additional functions in a computer, online, mobile, and the like.

The separate channel file is preferably configured in the last channel of the sound source file. The channel file is not reproduced at the time of playing a simple sound source, but in a player that recognizes the channel file, images, lyrics, hidden voices of a singer, etc. are displayed, and various services can be created.

On the other hand, the multi-channel sound source file has channel reproduction information storing reproduction information of each channel file, that is, decoding pattern information of each channel file.

The channel reproduction information stores time, frequency band, and two-dimensional spatial information corresponding to the channel file. The channel file is arranged and reproduced at a specified position in a frequency band designated at a specific time zone according to the information stored in the channel reproduction information.

The multi-channel sound source file further includes sound source reproduction information having a plurality of specific channel configuration information constituting the sound source file and total channel reproduction information for the channel file.

 The multi-channel sound source files established and encoded in the multi-channel as described above are also produced in the form of audio files, and can be used on or offline only in the file form, and can be used in all audio environments depending on the storage medium.

In this case, the encoded multi-channel sound source file is stored in a multi-channel sound source file database of a service provider, that is, the multi-channel sound source file providing server 200, and is provided to a user to use later.

Service providers, that is, users authenticated using the authentication program of the multi-channel sound source file providing server 200, download and play the multi-channel sound source file to their playback apparatus 100 or press the play button on the Internet to multi-play. The channel sound source file is played (S270).

Steps S200 to S270 presented above are essential operation steps of the present invention, and the steps described below may be selectively operated.

The user who has downloaded the multi-channel sound source file can select and play only a specific sound, ie, a specific channel file, by the user interface. Since the multi-channel sound source file according to the present invention is encoded to enable sound source control for each channel file, only a specific channel file can be reproduced.

3 illustrates an example of a user interface when reproducing a sound source file using only a specific channel file.

The user interface displays each channel file of the sound source file in a playback device downloaded by the user or a display unit on the Internet (S300).

The user inputs a channel file that the user wants to hear using the user interface (S310). When the channel file request is stored from the user, the sound source file is output only with the stored channel file (S320).

The multi-channel sound source file produced by the present invention can be individually controlled for each channel file, and additional information (eg, image, URL, karaoke, and other information) other than the sound source is configured as a separate channel to create various additional services. It is possible.

For example, the multi-channel sound source file further includes a channel file encoded to display Korean lyrics or translated lyrics and images. When the sound source file is played, the user may listen to the lyrics and images together with music. Can be.

4 is a flowchart showing a multi-channel sound source arrangement according to the user selection method of the present invention.

Steps S200 to S270 operate in the same manner as in the preferred embodiment. That is, the multi-channel sound source file providing server 200 receives existing music from the user, encodes the selected sound source file into a multi-channel sound source file that can be controlled by channel file, and provides the same to the user.

The user downloads one or more multi-channel sound files to be combined by the user using the user interface (S420).

The user interface displays each channel file of the sound source files on a playback device downloaded by the user or on a display unit on the Internet (S420).

The user reconstructs the channel file by extracting only the channel file that the user wants to hear using the user interface (S430). When the channel file request is saved from the user, the file is output in the configuration form of the stored channel file.

The multichannel sound source file includes channel reproduction information and sound source reproduction information.

The channel reproduction information stores time, frequency band, and two-dimensional spatial information corresponding to the channel file. The channel file is arranged and reproduced at a specified position in a frequency band designated at a specific time zone according to the information stored in the channel reproduction information.

The sound source reproduction information stores a plurality of specific channel file configuration information constituting the multi-channel sound source file and all channel reproduction information for the channel file.

The sound source reproduction information may be newly updated according to a user's request by using the user interface.

As shown in FIG. 5, the user interface separately displays and displays channel files of one or more multichannel sound source files downloaded by a user input, receives a request from the user, reconstructs the channel files, and reproduces the sound source in its form. You can play the file.
