Description

Apparatus and method for playing digital sound file able to output modulating by discernment information}

The present invention relates to an apparatus for reproducing digitized sound source data, and more particularly, to an apparatus and method for reproducing a sound source file in which the output is automatically adjusted when the sound source is reproduced.

Recently, due to the increased interest in digital music by the general public, sound source compression and playback technologies such as MP3 codec have been developed and are being developed day by day. In addition, development of related devices such as MP3 players, MP3 phones, and portable multimedia players is in full swing based on these technologies. As such, the recent trend of music is prevalent in the digital sound source (MP3) era through the era of the conventional record version and the compact disc.

Recently, as the demand for these devices increases, various products are being developed, and digital sound sources used for the digital sound sources have been developed and distributed in various ways. As an example of a practical application of a digital sound source, a user purchases a record, and then directly converts the desired music from the record into a digital sound source and stores it in a portable sound source playback device. At this time, digitization such as sound source extraction and conversion work is directly performed on the personal PC. As another example, a user may purchase a pre-produced digital sound source through a network and download and use a file. As in this example, users process the computer into sound source files or download the sound source files and store them on their mobile devices.

As in this application example, the majority of digital sound sources are not standardized so that sound files are generated according to subjective settings of users or producers. That is, for example, when the music is converted into a digital sound source file in the record, the volume size of the converted sound source file is arbitrarily set by the user who performs the conversion process. In this case, since the volume of each sound source file is different during playback, the user may have to adjust the volume every time the sound file is played.

In addition, even when the digital sound source file is generated at a constant level, since the playback settings of the devices that play the sound source file are all different, the sound source may be output at different settings for each device.

As such, the sound and volume types of digital sound sources are so diverse that when you store them in a digital playback device and listen to music, you need to adjust the settings such as sound and volume to suit your taste. There is a ham.

In addition, the user can not know the settings of the tone, volume, etc. of the digital sound source file, there is an inconvenience that the user must listen directly every time and change the settings to suit your taste. This is a very uncomfortable and annoying part that does not take into account the user's convenience, which is a recent trend, and it can be said that there is a need for realistic technology improvement for this problem.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an apparatus and method for reproducing a sound source in which various settings of a digital sound source can be collectively set according to the taste of each user.

Furthermore, another object of the present invention is to provide a method and apparatus for setting a user's taste using the digital sound source file itself without adjusting and converting the output setting of the digital sound source.

Further objects and advantages of the present invention can be understood by the following description, and will be more clearly understood by the embodiments of the present invention. Also, it will be readily appreciated that the objects and advantages of the present invention may be realized by the means and combinations thereof indicated in the claims.

Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a diagram illustrating a configuration of a digital sound source reproducing apparatus whose output is controlled by identification information according to an exemplary embodiment of the present invention.

The sound source reproducing apparatus according to the present invention reproduces and processes a digital sound source file (or a moving image digital file including audio information) stored in a recording medium as sound information, recognizes identification information included in the sound source file, and determines output setting information. And a digital device or a sound source playback software program for adjusting the output of the reproduced sound information according to the determined output setting information.

1, the sound source reproducing apparatus 100 according to the present invention includes a sound source reproducing module 110, an identification information determining module 120, an output adjusting module 130, and the like.

The sound source reproducing module 110 reads the digital sound source file stored in the recording medium and plays the sound information (voice, sound, audio). The sound source reproduction module 110 may perform decoding processing at the time of reproduction according to the type and format of the sound source file. That is, when the digital sound source file is encoded or compressed with a specific codec (eg, MP3), a process of decoding the digital sound source file is performed. In addition, the sound source playback module 110 performs a control process for the sound source playback. The control process is a control process for reproducing a sound source and performs general control such as start of playback, end, pause, change of playback point, repeat play, rewind, fast forward, and the like. In addition, the digital sound source file includes not only an audio sound source but also a moving image digital file including audio information.

The identification information determination module 120 extracts identification information included in a sound source file to be played and determines output setting information. The identification information determination module 120 includes an identification information extraction unit 122, a setting information determination unit 124, an identification table 125, a reproduction control information determination unit 126, and the like.

The identification information extracting unit 122 serves to extract identification information from the digital sound source file. That is, it plays a role of extracting identification information for identifying output setting information included in the sound source file reproduced by the sound source reproduction module 110. The identification information may be set in advance when the sound source is produced or generated, or may be arbitrarily changed and set by the user. In addition, the identification information may be included in the file name of the digital sound source file. That is, a combination of letters, numbers, symbols, etc., in an area separated by a specific identifier in the file name of the digital sound source file is recorded as identification information, and is recognized and extracted as identification information. Therefore, users can record and set identification information to their desired output setting by a simple method such as file name change.

The setting information determining unit 124 determines output setting information by using the identification information extracted by the identification information extracting unit 122. The output setting information includes a pitch, a tone, a volume, a tempo setting value, and the like when the sound source file is reproduced and output. The setting information determination unit 124 refers to the identification table 125 to be described later, and inquires the extracted identification information and determines corresponding output setting information accordingly.

The identification table 125 is a database in which output setting information corresponding to various identification information is divided and stored. Furthermore, the identification table 125 may include not only output setting information corresponding to the identification information but also playback control information for controlling sound source reproduction processing. Accordingly, output setting information and reproduction control information corresponding to the identification information are separately stored in the identification table 125.

That is, for example, identification information of all cases is recorded in the identification information item of the identification table 125, and the output setting information item and the reproduction control information item corresponding to the identification information item are provided, and each row of the identification information item is provided. The table can be constructed by recording the output setting value and the reproduction control value corresponding thereto.

The reproduction control information determination unit 126 serves to determine the reproduction control information by using the identification information extracted by the identification information extraction unit 122. The reproduction control information determination unit 126 inquires the extracted identification information to the identification table 125 to determine whether the corresponding reproduction control information exists, and when the reproduction control information exists, reproduces the sound source according to the reproduction control information. Control processing.

At this time, the sound source playback control process performed by the sound source playback module 110 can be controlled according to the determined playback control information. That is, for example, control processing such as changing the reproduction speed at the time of reproducing the sound source or repetitively repeating the reproduction is possible according to the reproduction control information.

Here, an example of the identification information included in the sound source file extracted by the identification information determination module 120 will be described with reference to FIG. 2.

2 is a diagram illustrating an example of identification information extracted by a digital sound source reproducing apparatus whose output is controlled by identification information according to an embodiment of the present invention.

As shown in FIG. 2, the identification information included in the sound source file may be included in the file name of the sound source file. First, looking at a general sound source file name, there is a sound source name area (e). Next, an area f for recording an extension in accordance with the format or method of the sound source exists at the rear end of the file name. In this case, the sound source name area (e) and the extension area (f) are generally separated by '.'.

In addition to this, an area for recording identification information can be added. In this embodiment, the identification information areas a to d are arranged between the sound source name area e and the extension area f.

The identification information areas (a to d) may be identified by identification symbols (a) indicating that they are identification information. That is, as shown in the drawing, the symbol '[', ']' may indicate that the identification information area. Character strings b to d included in the identification symbol (a) are utilized as identification information. Therefore, the identification information determination module 120 recognizes and extracts the character string recorded in the area between the identification symbols (a) of the sound source file name as the identification information. In this case, the character string recorded as identification information may include letters, numbers, symbols, and the like.

In the present embodiment, as shown in the figure, the character strings b to d which are identification information may be divided into three parts, and the character strings of the respective parts may correspond to the output setting information. First, two digits '15' of the first number string (b) may be used as identification information representing the volume of the output setting information. That is, in the example of the drawing, the volume of the corresponding sound source may be set to 15, or the original volume value may be represented as 15. The second two-digit string 'c' may be used as identification information representing the timbre of the output setting information. That is, in the example of the figure, the tone of the sound source may be set to the POP genre. The trailing four-character string '0000' can be used as an additional option for output configuration information. That is, in the drawing, no additional option is set, and output settings such as pitch and tempo can be specified according to the set value, and further, playback control information can be set in this area.

Here, since the identification information shown in FIG. 2 is only an example, the present invention is not limited thereto, and the identification information included in the file name may be recorded in various ways.

The output adjustment module 130 adjusts the output of the reproduced sound source according to the output setting information. That is, the output control module 130 outputs sound information, audio information, and voice information reproduced by the sound source reproduction module 110 according to the output setting information determined by the identification information determination module 120. The adjusting process takes place. The output control module 130 includes a volume controller 132, a tone controller 134, an additional option controller 136, a basic processor 138, and the like.

The volume adjusting unit 132 adjusts the output volume at the time of reproducing the sound source according to the output setting information. This is the usual volume control function. The tone adjusting unit 134 adjusts an output tone when reproducing a sound source according to the output setting information. These include common equalizers or effect controls, genre controls, and so on. For example, when the output setting information is POP, the tone of the reproduced sound source is adjusted to the pop music genre. The additional option adjusting unit 136 adjusts the output when the sound source is reproduced by reflecting the additional option when the additional option is set in the output setting information. Additional options include pitch settings and tempo settings.

The basic processing unit 138 adjusts the output of the sound source reproduced according to the basic setting set in the device itself when the result of determining the output setting information in the identification information determination module 120 does not exist or cannot be determined. Play a role. That is, adjust the output to the default value, or output the original sound source as it is being played. Of course, at this time, the user can directly manipulate the device to adjust the output.

As described above, the digital sound source reproducing apparatus 100 according to the present invention, the output is adjusted according to the identification information included in the sound source, the output is automatically adjusted as set in the sound source even if the user does not adjust the output separately.

3 is a flowchart illustrating a procedure of a digital sound source reproduction method in which an output is controlled by identification information according to an embodiment of the present invention.

Referring to FIG. 3, a procedure of a method of reproducing a digital sound source whose output is controlled by identification information according to an exemplary embodiment of the present invention, first, a procedure of receiving a selection of a sound source to be reproduced by searching a list of sound sources stored in a digital sound source reproducing apparatus by a user. Proceed. At this time, the stored sound source file includes identification information indicating the output setting information (S10).

If a sound source file is selected, a process of accessing and reading the sound source file and reproducing it with sound information, audio information, voice information, and the like proceeds. In this case, the decoding process and the decompression process may be performed in parallel according to the sound source file (S20).

Next, a procedure of extracting identification information from the selected corresponding sound source file is performed. In this embodiment, the identification information is extracted from the file name of the sound source file. That is, a procedure of recognizing a character string included between the identifiers of the file name as identification information and extracting the same is performed.

When the identification information is extracted, a procedure of determining output setting information corresponding to the identification information is performed by referring to the identification table. At this time, the determined output setting information is divided into volume, tone, pitch, and tempo setting value.

In addition, a procedure of checking whether identification information extraction and output setting information determination is impossible is performed. That is, in step S30, it is determined that the identification information does not exist in the sound source file or the case where the identification information cannot be extracted. In addition, when the output setting information cannot be determined through the identification information in step S40 or when there is no output setting information corresponding to the identification information in the identification table, it is determined that the output setting information cannot be determined. )

If it is determined that extraction and discrimination are impossible, the procedure of loading the preset default output setting value is performed. Here, the default output setting value may be set in the device itself. In addition, when the basic output setting value is not set in advance, the output setting value is set to no value. That is, it is the setting to output the sound source to be reproduced as it is without adjusting the output (S55).

On the other hand, if the output is determined to be extracted and determined as a result of the verification, the procedure for adjusting the output of the reproduction sound of the reproduced sound source is performed according to the set extraction setting information. At this time, the output of the volume, tone, etc. of the playback sound is adjusted according to the setting (S60).

After the output adjustment procedure, a procedure of outputting the output adjusted reproduction sound (sound information, audio information, voice information, etc.) through the output device (speaker, etc.) is performed.

4 is a flowchart illustrating a procedure performed in a user PC and a sound source playback apparatus according to a digital sound source playback method according to an embodiment of the present invention.

Referring to the drawing, first, a procedure of modifying a file name of a stored sound source file is performed on a PC. At this time, the sound source file is a state in which the user directly extracts from a record or the like is downloaded and stored through a network. Therefore, the identification information is not recorded or the identification information is not set according to the user's preference. The user can modify the file name of the sound source file by renaming.

Along with file name modification, a procedure is created for the user to create or change identification information in the file name. At this time, according to the user's taste, the identification information desired by the user is generated and changed. In addition, the identification information set once can be equally applied to many other sound source files. At this time, the identification information is also generated and changed through file name modification.

The sound source file having identification information set by the user is transferred to a sound source reproducing apparatus capable of reproducing a sound source from a PC and stored in a memory or the like. In this case, the sound source reproducing apparatus may be a separate portable digital sound source reproducing apparatus, or may be a sound source reproducing software program in a PC.

When the sound source file is transmitted and stored in the sound source reproducing apparatus, a sound source for reproduction is made from the user, and a reproduction processing procedure of the selected sound source is performed.

Along with the sound source reproduction processing, a procedure of adjusting the output of the reproduction sound according to the identification information included in the sound source is performed. That is, the identification information included in the corresponding sound source file is extracted, and through this, the output setting information is determined, and the output is adjusted according to the setting value.

The reproduced sound adjusted in this way is output to the outside through a speaker, etc. so that the user can enjoy it.

As described above, when the user generates or changes the identification information on the sound source file itself, the playback apparatus automatically adjusts the output to correspond to the identification information when the sound source is reproduced. Through this, the user can listen to the music whose output is adjusted according to the user's taste without manipulating the playback device. In addition, other heterogeneous devices can listen to the sound source with the output adjusted as set by the user without a separate operation.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto and will be described below by the person skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims.
