The server device 200 may separate the original sound source by using the selected sound source separator and may store or provide the result to the at least one electronic device 100. In the above-described operation, the server device 200 may select a test sound source corresponding to the original sound source among pre-stored test sound sources, and may select a sound source separator that provides optimal performance for the selected test sound source.

According to an embodiment, the server device 200 may provide the at least one electronic device 100 with a sound source list edited (or sound source elements are separated). When a specific edit sound source is selected by a user, and then a sound field effect (e.g., a type of an effect, sound source characteristics, or an application service, an application program, or a type of an application applied to the edit sound source such as editing) for the selected edit sound source element is selected, the server device 200 may select a sound source separator, which is capable of optimally providing the selected sound field effect, from among a plurality of sound source separators. The server device 200 may perform sound source separation on an original sound source by using the selected sound source separator, and may store the result in the server device 200 or provide the result to the at least one electronic device 100.

According to an embodiment, the at least one electronic device 100 may access the server device 200 based on address information of the server device 200 and may use a sound source edit function provided by the server device 200. In this operation, after the at least one electronic device 100 provides an original sound source (or content) to the server device 200, or selects at least one original sound source from among a plurality of original sound sources provided by the server device 200, the at least one electronic device 100 may request the server device 200 to separate a sound source from the corresponding original sound source. The at least one electronic device 100 may receive and output a sound source element, in which a sound source provided by the server device 200 is separated, or the edited sound source including the sound source element. Moreover, the at least one electronic device 100 may select at least one edited sound source provided by the server device 200 and may provide the server device 200 with a user input for adjusting a sound field effect for a specific sound source element included in the edited sound source. In response thereto, after the optimal sound source separator for applying a user selection sound field effect to the original sound source is selected by the server device 200, the original sound source corresponding to the edited sound source may be separated again by using the selected optimal sound source separator.

In the meantime, in the above description, it is described that the server device 200 stores a plurality of sound source separators, and the server device 200, which is a subject selecting the optimal (or providing performance of a specified level or higher) sound source separator depending on the characteristics of the original sound source, performs related operations, but the disclosure is not limited thereto. For example, at least one among the at least one electronic device 100 may include a plurality of sound source separators, and may perform an operation of selecting a sound source separator for sound source separation for an original sound source stored in the electronic device 100 or an original sound source received from an external electronic device.

Accordingly, the sound source separator selecting function of the disclosure may be provided through the server device 200, but may also be performed by the at least one electronic device 100 itself. The at least one electronic device 100 may receive and store a plurality of sound source separators capable of providing sound source separator selecting function from the server device 200. At least one sound source separator among the plurality of sound source separators may be composed of at least one of a processing module, a program, an application, or a trained deep learning model. According to an embodiment, in relation to the audio performance of an application program, which is currently running or which is selected by a user, the at least one electronic device 100 may select a sound source separator, which is capable of optimizing the corresponding audio function, from among a plurality of sound source separators.

The sound source separators 232 may have different numbers of sound source elements capable of being separated depending on their performance. Alternatively, the sound source separators 232 may have different distortion levels of the separated sound source elements depending on the performance thereof. According to an embodiment, the first sound source separator 232a among the sound source separators 232 may separate two first sound source element groups 233a (e.g., voices or background music (BGM)) from the original sound source (input). The second sound source separator 232b among the plurality of sound source separators 232 may extract four second sound source element groups 233b (e.g., a guitar, a piano, drums, or others) from the original sound source (input). According to an embodiment, the second sound source separator 232b may separate at least some sound source elements (e.g., voices or BGM) of the first sound source element group 233a separated by the first sound source separator 232a. The performance of sound source separation may vary depending on the performance of a sound source separator itself or hardware allocation amounts for operating the sound source separator.

Each of the sound source separators 232 may be matched to at least one test sound source. For example, the sound source separators 232 may include commercial sound source separators. For example, each of the sound source separators 232 may have a characteristic that the sound source separation performance for a specific sound source element is superior to the sound source separation performance for other sound source elements. Here, for example, the sound source separation performance may be identified depending on the distortion of the original sound source characteristics of a specific sound source element. For example, the sound source separators 232 include three sound source separators. One sound source separator, which has the lowest distortion when a voice is separated from the original sound source including the voice, from among the three sound source separators may be distinguished as the sound source separator having higher performance than the other sound source separators. According to an embodiment, at least some of the sound source separators 232 may have different memory allocation amounts and CPU amounts to be allocated at runtime. Alternatively, at least some of the sound source separators 232 may have different amounts of bandwidth that need to be allocated at runtime.

The edit sound source 233 may be information, which is stored after a specific sound source separator is selected from the sound source separators 232 and the original sound source is edited by the selected sound source separator. The edit sound source 233 may include at least some of an original sound source, information about sound source elements separated from the original sound source, type information about a sound source separator used during editing, or type information about a sound field effect (e.g., an effect type, sound source characteristics, or an application service, an application program or an application such as editing). At the request of the electronic device 100, the edit sound source 233 may be updated such that the edit sound source 233 is changed to a new edit sound source. The edit sound source 233 may store an address value, at which the original sound source is stored, without including the original sound source separately or may store the address value at which separated sound source elements are stored.

According to an embodiment, the server memory 230 stores a plurality of sound field effectors (or effect modules) and may provide a sound field effector list capable of being provided by the server device 200 at the request of the electronic device 100.

The server processor 250 may control the transmission and processing of signals for the operation of the server device 200 and the storage of the processed results. According to an embodiment, the server processor 250 may include an original sound source collection unit 251, a test sound source matching unit 252, a sound source separator selection unit 253, and an edit sound source management unit 254 in relation to supporting a sound source separator selecting function according to an embodiment.

The original sound source collection unit 251 may process original sound source collection. For example, when the electronic device 100 is connected, the original sound source collection unit 251 may assign a channel capable of providing or registering the original sound source, from which a sound source is separated. In this operation, the original sound source collection unit 251 may provide the electronic device 100 with an access screen including items related to original sound source registration. According to an embodiment, the original sound source collection unit 251 may collect the original sound source by accessing an external server device that provides the original sound source depending on a specified period. Alternatively, when receiving an update message for a specific original sound source from a specified external server device, the original sound source collection unit 251 may receive the original sound source from the external server device and may store the original sound source in the server memory 230.

The test sound source matching unit 252 may compare features of the original sound source, from which a sound source is requested to be separated, with features of test sound sources. For example, the test sound source matching unit 252 may extract a representative feature of the original sound source and may detect the test sound source (or a test vector) that is most similar to the representative feature (or has a similarity of a reference value or higher). According to an embodiment, the test sound source matching unit 252 may extract sound information (e.g., at least one of the genre of the original sound source, the number and types of musical instruments used in the original sound source, or the sound field effect applied to the original sound source) of an original sound source and may detect a test sound source having sound information identical or similar to the sound information. In this regard, at least some of the test sound sources 231 may include sound information capable of being compared to sound information stored in the original sound source. When a test sound source corresponding to the original sound source is detected, the test sound source matching unit 252 may deliver the detected test sound source to the sound source separator selection unit 253. According to an embodiment, the test sound source matching unit 252 may select the test sound source, by using classification information (e.g., ID3) registered in a file tag of the original sound source or by evaluating the similarity between a sound and the prepared test sound sources 231 (or a test vector set).

The sound source separator selection unit 253 may receive the test sound source from the test sound source matching unit 252 and may select a sound source separator matching the received test sound source from the plurality of sound source separators 232. In this regard, each or at least some of the plurality of sound source separators 232 stored in the server memory 230 may include information matching the test sound sources 231. Alternatively, the server memory 230 may store a matching table that matches the test sound sources 231 with the sound source separators 232. According to an embodiment, the sound source separator selection unit 253 may transmit the test sound source to a specified external server device having various sound source separators, and may also receive a sound source separator in software form (e.g., in a form of an application or a processing module) corresponding to the test sound source from the specified external server device.

According to an embodiment, the sound source separator selection unit 253 may identify the resource utilization status of the server device 200 (or an external server device) that will perform processing on the original sound source together with the test sound source. For example, the resource utilization status of the server device 200 (or the external server device) may include hardware resources (e.g., remaining memory capacity, remaining CPU capacity, and remaining power) of the server device 200 (or the external server device) and network resources (e.g., network data transmission speed and network delay time). The sound source separator selection unit 253 may determine whether the time required to separate a specific sound source is within a predefined reference value, and may select a sound source separator that separates a specific sound source within the reference value. When the sound source separator is on an external server device, the time required to download a sound source separator stored in the external server device and to separate the sound source by using the downloaded sound source separator, or the time required to separate a sound source by using a sound source separator stored in the external server device may be calculated, and a sound source separator whose calculated value is within the specified value may be selected. According to an embodiment, the sound source separator selection unit 253 may extract at least one sound source separator candidate group capable of being used based on the test sound source, and may select a sound source separator (or a sound source separator that provides the most optimal processing speed and processing time) that satisfies a specified processing speed or processing time among the sound source separator candidate group.

According to an embodiment, the sound source separator selection unit 253 may generate data for scoring the plurality of sound source separators 232 stored in the server memory 230 (or stored in the external server device). For example, the sound source separator selection unit 253 may calculate scores for a quality item (eval: SNR, SDR, SIR and similarity after sound effect by test) corresponding to quality performance quantitative values from the separated sound source results, a time (inference) item corresponding to the execution speed when a sound source is separated, a size (memory) item corresponding to the memory size used when a sound source is separated, and a system (capa) item (e.g., at least one of a central processing unit (CPU), a graphic processing unit (GPU), a neural processing unit (NPU) and/or a network element) corresponding to the performance indicator in a system. After calculating the final score of the calculated scores based on Equation 1, the sound source separator selection unit 253 may select a sound source separator to be used for sound source separation for the original sound source or sound field effect for the edit sound source based on the final score.

$\begin{array}{cc}\mathrm{score}=\alpha \times \mathrm{quality}\left(\mathrm{eval}\right)+\beta \times \mathrm{time}\left(\mathrm{inference}\right)+\gamma \times \mathrm{size}\left(\mathrm{memory}\right)+\delta \times \mathrm{system}\left(\mathrm{capa}\right)& \mathrm{Equation}1\end{array}$

In Equation 1, α, β, γ, and δ may be weight values, and may be constant values determined by a specified condition.

According to an embodiment, in relation to the system item, the sound source separator selection unit 253 may identify the current system status. For example, when a system is composed of a single processor, the sound source separator selection unit 253 may identify at least one of resources (e.g., at least one of the capacity of memory, a CPU, a GPU, a DSP, or an NPU), speed, and current consumption. When the system is composed of distributed processors, the sound source separator selection unit 253 may identify at least one of a system status (e.g., memory, speed, and current consumption) of the external processor, the status and delay time of a network, or the capability check result of the external processor. Moreover, the sound source separator selection unit 253 may select a sound source separator based on the checked result. The above-described operation may be identified at a point in time when the sound source separator is stored in the server memory 230 or at a point in time when an operation for selecting the sound source separator of an external server device is performed.

According to an embodiment, in relation to calculating the performance indicator of the sound source separator, the sound source separator selection unit 253 may obtain the sound source separation results according to applying each of the sound source separators 232 to the test sound sources 231. In addition, the sound source separator selection unit 253 may determine a primary state element in the single or distributed system to be used for the sound source separators by updating pieces of content of the system item for each sound source separator. For example, the sound source separator performance indicator may include at least one of SDR, SAR, SIR, SNR or similarity after a sound field effect is applied.

According to an embodiment, the SDR may be the distortion of the separated sound source or the distortion of the separated sound source to the original sound source (source) of the test sound source (or a test vector), and may be obtained based on Equation 2 below.

$\begin{array}{cc}\mathrm{SDR}=10{\log }_{10}\frac{{\sum }_n{s\left(n\right)}^2+ϵ}{{\sum }_n{s\left(n\right)-\hat{s}\left(n\right)}^2+ϵ},& \mathrm{Equation}2\end{array}$

The above-described SDR may indicate the degree of closeness to the intended sound source, and may indicate that the quality of the separated sound source (channel) is good, as the result value is great. In Equation 2, ‘s’ may denote a correct signal (ground truth); ŝ may denote the sound source (estimate) obtained from a sound source separator; and, ‘ε’ may denote any very small value for preventing the equation from becoming zero.

According to an embodiment, the SAR may indicate the sound source separation performance caused by the self-defect of the separated sound source and may be obtained based on Equation 3 below.

$\begin{array}{cc}\mathrm{SAR}:=10{\log }_{10}\frac{{s_{\mathrm{target}}}^2}{{e_{\mathrm{artif}}}^2}& \mathrm{Equation}3\end{array}$

In Equation 3, S_target may denote a correct signal, and e_artif may denote a noise value caused by a defect in the sound source separator itself. The SAR may indicate the degree of sound distortion of a separate sound source (channel) itself.

According to an embodiment, the SIR may indicate the sound source separation performance due to the influence of the next sound sources, and may be obtained based on Equation 4 below.

$\begin{array}{cc}\mathrm{SIR}:=10{\log }_{10}\left(\frac{{s_{\mathrm{target}}}^2}{{e_{\mathrm{interf}}}^2}\right)& \mathrm{Equation}4\end{array}$

In Equation 4, S_target may denote a correct signal, and e_interf may denote the noise value due to the influence of other channels. The SIR may indicate the influence of other signals remaining in a separate sound source (channel).

According to an embodiment, the SNR may indicate all noise effects related to sound source separation and may be obtained based on Equation 5 below.

$\begin{array}{cc}\mathrm{SNR}:=10{\log }_{10}\left(\frac{{s_{\mathrm{target}}}^2}{{s_{\mathrm{target}}-\hat{s}}^2}\right)& \mathrm{Equation}5\end{array}$

In mathematical expression 5, S_target may denote the correct signal, and may denote the sound source (estimate) obtained from the sound source separator.

According to an embodiment, after an effect (a sound field effect) is applied, the result similarity may be calculated based on Equation 6 below.

$\begin{array}{cc}\mathrm{similarity}\left(\mathrm{effect}\left(S_{\mathrm{target}}\right),\mathrm{effect}\left(\hat{S}\right)\right)& \mathrm{Equation}6\end{array}$

In Equation 6, S_target may denote a correct signal; $ may denote a sound source (estimate) obtained from a sound source separator; effect ( ) may denote an effect application function; and, similarity ( ) may denote a similarity calculation function.

The above-described sound source separation performance indicator may be used to standardize the performance of the plurality of sound source separators 232, and the sound source separator selection unit 253 may adopt and use at least one of the various performance indicator items described above. According to an embodiment, in relation to the performance of sound source separation, the sound source separator selection unit 253 may select a sound source separator in consideration of a system load (e.g., memory, a computational amount, or delay time) and the distortion of the separated sound source. Alternatively, the sound source separator selection unit 253 may select a sound source separator that has a higher SNR for voices by better identifying the voices, or a sound source separator for better performance on sound sources with specific harmonics such as a specific musical instrument or sound source type so as to match the original sound source. Alternatively, the sound source separator selection unit 253 may select a sound source separator having higher performance in a sound field effect application operation.

When the original sound source is separated by using the sound source separator selected by the sound source separator selection unit 253, the edit sound source management unit 254 may generate parameter information about the separated original sound source, and may store the edited sound source together with the generated parameter information in the server memory 230. For example, the parameter information may include at least one of the number of sound source elements separated from the original sound source, the type of a sound source elements separated, the type of a sound source separator used to separate an original sound source, or the time required to separate a sound source. The edit sound source management unit 254 may store and manage original sound source information corresponding to the edit sound source 233. The edit sound source management unit 254 may provide an edit sound source including parameter information to the electronic device 100 from which the separation of the original sound source is requested. Alternatively, the edit sound source management unit 254 may provide the electronic device 100 with a list of the at least one edit sound source 233 stored in the server memory 230, and may provide the electronic device 100 with the edit sound source according to user selection.

The edit sound source management unit 254 may receive, from the electronic device 100, a message for requesting a change in a sound field effect for a specific sound source element included in the edit sound source. In this case, the edit sound source management unit 254 may deliver, to the sound source separator selection unit 253, a message for requesting a change in the sound field effect and the original sound source corresponding to the edit sound source.

The sound source separator selection unit 253 may select an optimal sound source separator to change the sound field effect of a specific sound source element included in the original sound source. In this regard, the server memory 230 may store and manage a list of optimal sound source separators depending on changes in the sound field effect of the sound source element. The sound source separator selection unit 253 may identify the sound source separator list (e.g., at least one of identification information (e.g., the name or designation number of a sound source separator) of a sound source separator, storage location of the sound source separator, characteristics of the sound source separator (e.g., descriptions of the type of a sound source having the better performance), and sound source separator preference (including preference corresponding to choices of various users and preferred sound source information of the users) stored in the server memory 230, may select a sound source separator optimized for the original sound source, from which a user makes a request for separating a sound source and to which the user makes a request for applying a sound field effect, may re-perform sound source separation on the original sound source by using the selected sound source separator, and may create a new edit sound source by applying the sound field effect to the sound source element specified by the user among the sound source elements according to the re-performing of the sound source separation. The edit sound source management unit 254 may process updating parameter information about the new edit sound source.

According to an embodiment, the sound source separator selecting function may be performed in, for example, the electronic device 100. In this case, the above-described operation of the server processor 250 may correspond to the operation of the processor 150 of the electronic device 100. According to an embodiment, at least one of at least one sound source separator, an original sound source, a test sound source (or a test vector), an effect module (or a sound field effector), or a computing device for selecting a sound source separator may be in an external network and may be used as a system (capa) element for selecting the sound source separator.

FIG. 4 is a diagram illustrating an example of sound source separation by a plurality of sound source separators, according to an embodiment of the disclosure.

Referring to FIGS. 3 and 4, when a sound source separation request for an original sound source (input) occurs, the server processor 250 may select at least one sound source separator from the plurality of sound source separators 232 stored in the server memory 230 (or a plurality of sound source separators stored in an external server device) and may perform sound source separation on the original sound source (input) based on the selected sound source separator. According to an embodiment, the main configuration of a sound source separator may include basic information (e.g., at least one of a name, a version, url (including local), a size, or dependency (requirement) library), an input type (e.g., data, a format, a sampling rate, and a channel), and an output type (e.g., data, a format, a sampling rate, and a channel (information)).

Referring to the illustrated drawings as an example, the plurality of sound source separators 232 may at least include the first sound source separator 232a and the second sound source separator 232b. The server processor 250 may select the first sound source separator 232a and the second sound source separator 232b in relation to sound source separation for the original sound source (input) under a specified condition. The server processor 250 may generate the first edit sound source 233a and the second edit sound source 233b by separating a sound source from the original sound source (input) by using the selected sound source separators 232a and 232b. According to an embodiment, the first edit sound source 233a may include voices and BGM sound source elements. The second edit sound source 233b may include a guitar, a piano, drums, and other sound source elements. The server processor 250 may generate parameter information for sound source elements of the first edit sound source 233a that is generated, may include the parameter information in the first edit sound source 233a, and may store the first edit sound source 233a in the server memory 230. In this operation, the server processor 250 may include information about the original sound source (input) in the first edit sound source 233a and may store the first edit sound source 233a. For example, the parameter information included in the first edit sound source 233a may at least include identification information of the first sound source separator 232a, types of sound source elements, and information about the number of sound source elements.

Moreover, the server processor 250 may generate parameter information about sound source elements of the generated the second edit sound source 233b, may include the parameter information in the second edit sound source 233b, and may store the second edit sound source 233b in the server memory 230. Moreover, the server processor 250 may include information about the original sound source (input) in the second edit sound source 233b and may store the second edit sound source 233b. For example, the parameter information included in the second edit sound source 233b may at least include identification information of the second sound source separator 232b, types of sound source elements, and information about the number of sound source elements.

In the meantime, in the above descriptions, it is described that the server processor 250 selects the first sound source separator 232a and the second sound source separator 232b, but the disclosure is not limited thereto. For example, the server processor 250 may select only one sound source separator among the first sound source separator 232a and the second sound source separator 232b under a specified condition. In response, one of the first edit sound source 233a separated by the first sound source separator 232a and the second edit sound source 233b separated by the second sound source separator 232b may be stored in the server memory 230. According to an embodiment, the plurality of sound source separators may include a third sound source separator capable of separating at least one of multiple speakers, chorus, acoustic, electronic sound, spatial sound, sound effects, or noise as a sound source element, and may separate at least one of the above-described sound source elements as a sound source in this way.

FIG. 5 is a diagram illustrating an example of a method of operating a plurality of sound source separators, according to an embodiment of the disclosure.

Referring to FIG. 5, in connection with a method of operating a plurality of sound source separators according to an embodiment, in operation 501, the server processor 250 (or the processor 150 of the electronic device 100, hereinafter described based on the server processor 250) of the server device 200 may control collection of an original sound source. For example, the original sound source may be provided by the electronic device 100, or the original sound source stored in the server memory 230 may be selected or may be received from an external server device. In this regard, the server processor 250 may provide a menu item for uploading the original sound source onto the electronic device 100 while a communication channel with the electronic device 100 is established, and may receive the original sound source from the electronic device 100 through the corresponding menu item. When the server processor 250 receives the original sound source from the electronic device 100, the server processor 250 may temporarily or semi-permanently store the received original sound source in the server memory 230. According to an embodiment, the server processor 250 may provide the electronic device 100 with a list screen for selecting the original sound source to be used for sound source separation, and a user may select a specific original sound source on the list screen. In this operation, the server processor 250 may provide a pre-listening function for an original sound source capable of being selected by the user of the electronic device 100. The electronic device 100 may receive and output the original sound source stored in the server memory 230 in a streaming manner or may download and play the original sound source. The server processor 250 may receive a search word for a specific original sound source from the electronic device 100. When the original sound source corresponding to the search word is not stored in the server memory 230, the server processor 250 may receive the original sound source corresponding to the search term from an external server device.

In operation 503, the server processor 250 may select a test sound source. In relation to selecting the test sound source, the server processor 250 may identify sound information (or meta information) of the original sound source selected by the user of the electronic device 100, and may select a test sound source having sound information identical to or similar to the sound information from a plurality of test sound sources. When the sound information is not present in the original sound source, the server processor 250 may select the test sound source having a similar waveform by analyzing the waveform of a signal included in the original sound source. In this operation, the server processor 250 may sample at least part of the entire interval of the original sound source and may select the test sound source having a sample interval identical or similar to the sampled interval. The test sound sources 231 pre-stored in the server memory 230 may be matched with the optimized (or the degree of distortion is less than a reference value, or is the lowest compared to other sound source separators) sound source separator. The server memory 230 may store and manage a table matching the test sound sources 231 with the optimal sound source separator. When the server processor 250 downloads and installs a new sound source separator from an external server device, the server processor 250 may perform sound source separation on the test sound sources 231, may evaluate the sound source separation results to determine the optimal test sound source, and may update the matching table.

When the test sound source is selected, in operation 505, the server processor 250 may select a sound source separator. In this regard, the server processor 250 may identify the matching table pre-stored in the server memory 230, and may select a sound source separator having optimal performance (or performance having a specified reference value or higher, or performance indicating the degree of distortion lower having less than a reference value) for the selected test sound source among a plurality of sound source separators. For example, the sound source separator selection unit 253 may calculate scores for a quality item (eval: SNR, SDR, SIR and similarity after sound effect by test) corresponding to quality performance quantitative values from the sound source separation results performed previously (or performed by using the test sound source), a time (inference) item corresponding to the execution speed when a sound source is separated, a size (memory) item corresponding to the memory size used when a sound source is separated, and a system (capa) item (e.g., at least one of a central processing unit (CPU), a graphic processing unit (GPU), a neural processing unit (NPU) or a network element) corresponding to the performance indicator in a system, and may select a sound source separator to be used for sound source separation for the original sound source or sound field effect for the edit sound source based on the final score.

In operation 507, the server processor 250 may create an edit sound source by separating the original sound source by using the selected sound source separator. When a plurality of sound source separators are selected in operation 505, the server processor 250 may create a plurality of edit sound sources. The edited sound source may include a plurality of sound source elements.

In operation 509, the server processor 250 may control the storage of the edit sound source. For example, the server processor 250 may store the edit sound source in the server memory 230. According to an embodiment, the server processor 250 may provide the electronic device 100 with an edit sound source in response to a sound source separation request for an original sound source of the electronic device 100. When the plurality of edit sound sources for the original sound source are created, the server processor 250 may provide the plurality of edit sound sources to the electronic device 100. Alternatively, the server processor 250 may provide a list of edit sound sources to the electronic device 100 and may provide the electronic device 100 with the edit sound source according to the user's selection.

FIG. 6 is a diagram illustrating an example of a method of operating a plurality of sound source separators, according to an embodiment of the disclosure.

Referring to FIG. 6, in connection with a method of operating a plurality of sound source separators according to an embodiment, in operation 601, the server processor 250 (or the processor 150 of the electronic device 100, hereinafter described based on the server processor 250) of the server device 200 may provide a predefined access screen (or a web page) to the electronic device 100 when the electronic device 100 is accessed. For example, the access screen may include an edit sound source list stored in the server memory 230. The electronic device 100 may display the received edit sound source list on a display and may transmit, to the server device 200, the edit sound source selected in response to a user input.

In operation 603, the server processor 250 may determine whether the electronic device 100 selects the edit sound source. According to an embodiment, the access screen provided in the electronic device 100 may further include a menu item for selecting an original sound source separating function, a menu item related to the playback of the original sound source, or the like. Accordingly, when the user input is not an input for selecting an edit sound source, in operation 605, the server processor 250 may provide a specified function according to the user input. For example, the server processor 250 may support functions related to a specific sound source such as an original sound source searching function, an original sound source playing function, and an original sound source separating function.

When the user input received from the electronic device 100 is an input for selecting an edit sound source, in operation 607, the server processor 250 may output sound source elements of the selected edit sound source. In this operation, the server processor 250 may generate a list corresponding to a plurality of sound source elements of the edit sound source, and may provide the generated sound source element list to the electronic device 100. According to an embodiment, the sound source element list may include at least one of the types of sound source elements, whether sound field effects are applied to sound source elements, and the types of sound field effects applied to sound source elements. The electronic device 100 may transmit, to the server device 200, a message for instructing a change in the sound field effect of a specific sound source element in response to a user input.

In operation 609, the server processor 250 may determine whether a user input related to a sound field effect change occurs. When receiving a user input regarding a change in the sound field effect of a specific sound source element, in operation 611, the server processor 250 may select a sound source separator. In this operation, in applying a sound field effect to a sound source element selected by a user, the server processor 250 may select a sound source separator, which provides performance (or optimal performance) of a predetermined reference value or higher, from among a plurality of sound source separators. In this regard, the server memory 230 may store sound field effect information and a sound source element, through which each sound source separator is capable of providing high performance, in a table form. The server processor 250 may select a sound source separator for providing a sound source element and a sound field effect, which are selected in response to the user input, by identifying an information table stored in the server memory 230.

When a sound source separator is selected, the server processor 250 may identify the original sound source corresponding to an edit sound source. In operation 613, the server processor 250 may perform the separation task of the original sound source corresponding to the edit sound source by using the selected sound source separator. The server processor 250 may extract a plurality of sound source elements by performing a sound source separation task from the original sound source, and then may create a new edit sound source to which a sound field effect selected by the user is applied to the extracted sound source elements.

In operation 615, the server processor 250 may update the newly created edit sound source to the server memory 230. In the update operation, while deleting a pre-stored edit sound source and storing a new edit sound source or keeping a previous edit sound source, the server processor 250 may add the new edit sound source. The server processor 250 may provide the new edit sound source to the electronic device 100.

In the meantime, in the above description, it is described that the original sound source is separated by using a newly selected sound source separator to apply a specified sound field effect to at least one sound source element, which is selected by the user, from among sound source elements included in the edit sound source, but the disclosure is not limited thereto. For example, the server processor 250 may apply a sound field effect requested by the user to sound source elements included in the previous edit sound source, and a new edit sound source according to the sound field effect may be generated under the control of the server processor 250.

According to an embodiment, the server processor 250 may provide the user of the electronic device 100 with a new edit sound source registered by the user of another electronic device. As such, the server processor 250 may support other users such that the other users share the form for editing or re-editing a specific original sound source or an edit sound source, through a function for sharing or recommending the edit sound source. Moreover, the server processor 250 may apply a voting function (or a scoring function) to at least one edit sound source, such that the other users may check and view the edit sound source having a relatively good score.

In the meantime, in the descriptions given in FIGS. 5 and 6, the original sound source edit function and the edit sound source using function are described based on the server processor 250, but the above-described operations of FIGS. 5 and 6 may be identically applied to the operations of the processor 150 of the electronic device 100.

FIG. 10 is a diagram illustrating an example of providing an object related to selecting a sound source element, according to an embodiment of the disclosure.

When the electronic device 100 accesses the server device 200, the server device 200 may provide the electronic device 100 with a screen including at least one item among an item related to editing the original sound source (e.g., sound source separation) and an item for searching for edited sound sources. The user of the electronic device 100 may select one edit sound source among the edited sound sources on a screen provided by the server device 200; an input signal corresponding to a user's selection may be provided to the server device 200; and the server device 200 may provide a screen corresponding to the edit sound source selected by the user to the electronic device 100.

According to an embodiment, referring to FIG. 10, the server device 200 may provide the electronic device 100 with a screen including five sound source elements 1001, 1002, 1003, 1004, and 1005 in response to a user input for selecting a specific edit sound source among the edited sound sources. For example, the five sound source elements 1001, 1002, 1003, 1004, and 1005 of the edit sound source according to the user's selection may include the voice sound source element 1001, the guitar sound source element 1002, the drum sound source element 1003, the violin sound source element 1004, and the piano sound source element 1005. The sound source elements 1001, 1002, 1003, 1004, and 1005 output to the display 140 of the electronic device 100 may be output in a form of specific icons as illustrated, but the disclosure is not limited thereto. For example, text for describing icons (e.g., a voice, a guitar, drums, a violin, and a piano) respectively corresponding to the sound source elements 1001, 1002, 1003, 1004, and 1005 output to the electronic device 100 in addition to the icons may be output adjacent to the icons.

FIG. 11 is a diagram illustrating an example of a screen interface related to adjustment of a sound field effect of a single sound source element, according to an embodiment of the disclosure.

Referring to FIGS. 10 and 11, the server device 200 (or the electronic device 100) may provide functions for applying the sound field effect and volume of a specific sound source element. According to an embodiment, as illustrated in state 1110, the server device 200 may output an adjustment object related to adjusting of the volume and sound field effect of a voice sound source element object 1101. For example, the adjustment object may be configured to adjust the volume of the voice sound source element in a vertical direction (or x-axis direction), and to change the sound field effect (e.g., Pop, Classic, Flat, Jazz, and Rock) of the voice sound source element in a horizontal direction (or y-axis direction) (e.g., an application service, an application program, or an application such as an effect module, a sound source characteristic change module, and an editing module).

According to an embodiment, as illustrated in state 1120, a user of the electronic device 100 may vertically move the voice sound source element object 1101 to the top to adjust the volume of the voice sound source element. Alternatively, as illustrated in state 1130, a user of the electronic device 100 may vertically move the voice sound source element object 1101 to the bottom to adjust the volume of the voice sound source element. When the voice sound source element object 1101 in state 1110 is moved upwardly in a vertical direction as illustrated in state 1120, the server device 200 (or the electronic device 100) may adjust the setting of the sound source element such that the volume of the voice sound source element increases, and may output a first voice sound source transformation object 1101_1 upwardly in the vertical direction in response to the volume increase setting. For example, the first voice sound source transformation object 1101_1 may be displayed such that the size of the first voice sound source transformation object 1101_1 is greater than the voice sound source element object 1101.

When the voice sound source element object 1101 in state 1110 is moved downwardly in the vertical direction as illustrated in state 1130, the server device 200 (or the electronic device 100) may adjust the setting of the sound source element such that the volume of the voice sound source element decreases, and may output a second voice sound source transformation object 1101_2 downwardly in the vertical direction in response to the volume decrease setting. For example, the second voice sound source transformation object 1101_2 may be displayed such that the size of the second voice sound source transformation object 1101_2 is smaller than the voice sound source element object 1101.

In the meantime, as described in FIG. 11, it is described that the volume of the voice sound source element is adjusted, but other sound source elements may also be adjusted through the adjustment object described in FIG. 11. For example, when a user input for selecting a specific sound source element among the five sound source elements 1001, 1002, 1003, 1004, and 1005 illustrated in FIG. 10 occurs, the server device 200 (or the electronic device 100) may output an adjustment object capable of adjusting at least one of the volume or sound field effect for the selected sound source element, and the at least one of the volume or sound field effect may be adjusted depending on the movement of the sound source element as described in FIG. 11.

According to various embodiments, the adjustment object capable of adjusting the volume and the sound field effect is presented in the above-described FIG. 11, but the server device 200 (or the electronic device 100) of the disclosure may provide only one of a vertical adjustment object for adjusting the volume or a horizontal adjustment object for adjusting the sound field effect.

FIG. 12 is a diagram illustrating an example of a screen interface related to adjustment of a sound field effect of multiple sound source elements, according to an embodiment of the disclosure.

Referring to FIGS. 10 to 12, as described above in FIG. 10, the server device 200 (or the electronic device 100) according to an embodiment may output the sound source elements 1001, 1002, 1003, 1004, and 1005 included in an edit sound source selected by a user. While the plurality of sound source elements 1001, 1002, 1003, 1004, and 1005 are output, the user may select the plurality of sound source elements in relation to adjusting at least one of the volume or the sound field effect of a sound source element. For example, the user may select all five sound source elements to adjust the at least one of the volume or the sound field effect of all five sound source elements described in FIG. 10.

In response thereto, the server device 200 (or the electronic device 100) may provide a function for applying the volume and sound field effect of the plurality of sound source elements. According to an embodiment, the server device 200 may output an adjustment object capable of adjusting the volume and sound field effect of each of the voice sound source element object 1101, a piano sound source element object 1105, a guitar sound source element object 1102, a violin sound source element object 1104, and a drum sound source element object 1103. As illustrated in state 1210, the user of the electronic device 100 may set the volume of the voice sound source element object 1101 and the piano sound source element object 1105 so as to be relatively higher than the volume of other sound source elements (e.g., a guitar, a violin, or drums). As described above in FIG. 11, the server device 200 (or the electronic device 100) may display the sizes of the sound source element objects differently depending on a location on the vertical setting line.

According to an embodiment, as illustrated in state 1220, the volume and sound field effect of at least one sound source element may be adjusted simultaneously. For example, when the voice sound source element object 1101 is positioned at a left edge (e.g., a location corresponding to a Pop sound field effect) as shown while being placed above a horizontal line, the volume level of the voice sound source element may be set to be higher than the volume level of the sound source element positioned on the horizontal line, and the Pop effect may be applied as a sound field effect. As shown, when the piano sound source element object 1105 is positioned in the second quadrant corresponding to a location on the left side (e.g., the location corresponding to the Classic sound field effect) while being placed above the horizontal line, the volume level of the piano sound source element may be set higher than the volume level of the voice sound source element, and the Classic effect may be applied as a sound field effect. As shown, when the drum sound source element object 1103 is placed in the fourth quadrant corresponding to a right edge location (e.g., the location corresponding to the Rock sound field effect) while being placed below the horizontal line, the volume level of the drum sound source element may be set lower than the volume level set on the horizontal line or the volume level of the voice sound source element, and the Rock effect may be applied as a sound field effect. As shown, the violin sound source element object 1104 and the guitar sound source element object 1102 may be located at the lower side of a vertical line, and “Flat” may be set as a sound field effect. Here, the “Flat” sound field effect may include settings where no separate sound field effect is applied. In response thereto, the volume of each of the violin sound source element and the guitar sound source element may be set to minimum. As described above, when the same settings as in state 1220 are applied, the violin and guitar sound source elements in the edit sound source described in FIG. 10 may be removed, “POP” effect may be applied to a voice, a sound may be played at a volume level between a piano and a drum, the piano may be played at the highest volume while “Classic” effect is applied, and the drum may be played at a lower volume than the voice while “Rock” effect is applied. Referring to adjustment object settings in state 1220, the server device 200 (or the electronic device 100) may change color when applying a specific sound field effect.

FIG. 13 is a diagram showing an example of a screen interface for applying a sound field effect for each sound source element, according to an embodiment of the disclosure.

Referring to FIGS. 12 and 13, as described above in FIG. 12, the sound field effect of a specific sound source element may be changed or adjusted by placing an object corresponding to a specific sound source element at a location corresponding to a specific sound field effect of a horizontal line.

According to an embodiment, when only a voice (vocal) is to be emphasized, a user of the electronic device 100 may perform the same settings as in state 1310. For example, state 1310 may include a state where the volume of the voice sound source element is set to the maximum and the volume level of other sound source elements (e.g., a guitar sound source element, a drum sound source element, a violin sound source element, and a piano sound source element) are set to the minimum.

According to an embodiment, when only BGM is to be emphasized, a user of the electronic device 100 may perform the same settings as in state 1320. For example, state 1320 may include a state where the volume of the voice sound source element is set to the minimum and the volume level of other sound source elements (e.g., a guitar sound source element, a drum sound source element, a violin sound source element, and a piano sound source element) are set to the maximum.

According to an embodiment, when adjusting bits of sound source elements, the user of the electronic device 100 may perform the same settings as in state 1330. For example, state 1330 may include a state where no separate sound field effect is applied (or setting to “Flat”) while the volume of the voice sound source element, the guitar sound source element, the violin sound source element, and the piano sound source element is set to the maximum, and the volume of the drum sound source element is set to the maximum while “Rock” sound field effect is applied.

According to an embodiment, when various types of sound sources are adjusted depending on the user's settings, the user of the electronic device 100 may perform the same settings as in state 1340. For example, state 1340 may include a state where the Pop sound field effect is applied while the volume level of the voice sound source element is set to be lower than the volume level of the piano sound source element and higher than the other sound source elements, the Classic sound field effect is applied while the volume level of the piano sound source element is set to the maximum, and the volume levels of other sound source elements (e.g., the guitar sound source element, the drum sound source element, and the violin sound source element) are set to the minimum.

FIG. 14 is a diagram showing an example of a screen interface related to a sound field effect, according to an embodiment of the disclosure.

Referring to FIG. 14, when the sound field effects as described in FIGS. 11 to 13 are additionally or separately expressed with specific text or color in the operation of applying a sound field effect, the server device 200 (or the electronic device 100) may use specific poses or gesture shapes in relation to the expression of the specific sound field effect. According to an embodiment, the server device 200 (or the electronic device 100) may assign an image corresponding to a specific pose or gesture of a person corresponding to each of Pop, Classic, Flat, Jazz, and Rock sound field effects, may replace the image with icons provided to apply the sound field effects described in FIGS. 11 to 13, and may output the icons.

A user of the electronic device 100 may identify a specific pose or gesture (or identify text placed below the specific pose or gesture) and may select the sound field effect to be applied.

When receiving a user input related to adjusting the sound field effect of a specific sound source element in the above-described FIGS. 10 to 14, the server device 200 (or the electronic device 100) may select an appropriate sound source separator to apply the sound field effect selected by the user to the corresponding sound source element. In this regard, in applying a specific sound field effect to a specific sound source element, the server device 200 (or the electronic device 100) may store and manage a list of sound source separators or sound field effectors for providing a performance indicator (or an optimal performance indicator) of a reference value or more. The server device 200 (or the electronic device 100) may perform a related function by identifying a pre-stored list, and selecting a sound field effector or sound source separator for applying a sound field effect to a specific sound source element. In this operation, when selecting a sound source separator, the server device 200 (or the electronic device 100) may obtain an original sound source corresponding to an edit sound source, and may process sound source separation for the obtained original sound source and application of a sound field effect to a sound source element selected by the user among the sound source separated sound source elements.

In the meantime, it is described that a sound source separator is selected and an edit sound source is generated by the server device 200, but the description is not limited thereto. For example, instead of the server processor 250 of the server device 200, the processor 150 of the electronic device 100 may process at least one function of selecting a sound source separator, creating an edit sound source, selecting a new sound source separator for a specific sound source element in the edit sound source, separating a sound source of an original sound source by using the newly selected sound source separator, and updating a new edit sound source obtained by applying a sound field effect according to the user's selection to a sound source element. According to an embodiment, the sound source separating function of the disclosure may be provided by the electronic device 100 itself without connection to the server device 200. In this case, the electronic device 100 may store a plurality of sound source separators and at least one edit sound source in the memory 130, and may provide a sound source separator selecting function or a re-edit function for the edit sound source. In this regard, as an application supporting at least one of the sound source separator selecting function and the re-edit function described above is installed, and the corresponding application is launched, the electronic device 100 may support a screen interface providing function related to sound field effect editing in FIGS. 10 to 14 described above.

With respect to sound field effects after an optimal sound source separator is selected as described above in FIGS. 7 to 9, the sound source separator selecting function and the edit sound source using function of the disclosure described above may be applied in a form of metadata. In this disclosure, when conditions and arguments of sound source elements of a sound to be edited are given in a system including a plurality of different sound source separators, it is possible to select an appropriate sound source separator and to extract sound source elements, thereby providing a sound field effect. In this disclosure, the sound field effects of the edit sound source recorded in the form of metadata may be played in a single or mixed method, and the corresponding data may be operated such that one or more processors or devices of a plurality of terminals (a mobile, an AR, and a server) may share, add, and update the corresponding data.

Through the above-described user function of the disclosure, an effect (a sound field effect) may be applied to each separated sound source, and a model in which sound source separation and a sound field effect modules are separated or integrated may be used. Additionally, in the disclosure, adjustments such as frequency, pitch, and reverb may also be supported in relation to the sound field effect adjusting function. In this disclosure, the settings of individual or selected sound sources may be changed simultaneously, and separate effects suitable for sound source characteristics may be provided or recommended. A device (e.g., the server device 200 or the electronic device 100) of the disclosure may support recording one or more of setting values changed in the edit sound source or re-edit sound source operation in accordance with a file format (metainfo), and may support selecting and listening to a plurality of sound sources during playback. The device of the disclosure supports displaying setting values in various ways and applying an effect (e.g., pitch, style-transfer, svs, or sound effect engine (SEE)) to tone. Moreover, the disclosure may support a translation function (e.g., a function that generates and provides a script for a voice (vocal) for a language, and may support the creation of a vocal from the script. The material may apply effects to the sense of space (Spatial), and may support at least one function of a function of applying sound field effects overlapping, storing, sharing, and updating the set sound field effect, and differently applying the set sound field effect for each sound source, a function of differently displaying a sound source depending on a song, a function of providing a recommendation function accordingly when user preference information is collected, and differently applying effects to an image according to the sound source, a sound source recommending function according to the image, a ranking function for a setting sound field effect, a tag adding function, and a function of displaying and transferring copyright.
