Specifically, the first input is an acquisition instruction or a recording instruction input by a user to the electronic device. The application can ensure the correspondence between the multimedia information and the noise reduction information in the process of storing the multimedia information and the noise reduction information, and can ensure the correspondence between the obtained multimedia information and the noise reduction information.

Particularly, the method for acquiring the multimedia information can respectively acquire the multimedia information and the noise reduction information corresponding to the multimedia information when acquiring the multimedia information; thus, when the multimedia information is played later, the user can freely select whether to perform noise reduction processing on the multimedia information, and the noise reduction and the noise non-reduction are allowed to be switched in the playing process of the user, and even the noise reduction intensity is allowed to be switched by the user.

In addition, in the process of acquiring the multimedia information and the noise reduction information, the user often does not know the actual effect of the multimedia information after noise reduction, which may cause that the noise reduction effect of the multimedia information is inconsistent with the user's expectation when the multimedia information is played later. Therefore, the method and the device respectively store the multimedia information and the noise reduction information corresponding to the multimedia information in the acquisition stage, so that a user can perform noise reduction processing on the multimedia information according to actual experience and needs in the subsequent process of playing the multimedia information, and the playing effect of the multimedia information is greatly improved.

Further, in one embodiment of the present application, as shown in fig. 3 and 4, the multimedia information includes: video information and audio information which is not subjected to noise reduction processing; and, the noise reduction information includes a noise reduction state and a noise reduction intensity. That is, in the process of acquiring the multimedia information and the noise reduction information, the present application may acquire the video information, the audio information that is not subjected to the noise reduction processing, and the noise reduction state and the noise reduction strength corresponding to the audio information, respectively. Specifically, the noise reduction states include a noise reduction on state and a noise reduction off state.

Specifically, as shown in fig. 4, in the process of acquiring the multimedia information and the noise reduction information, if the audio information is not subjected to noise reduction processing under the first input; here, video information, audio information which has not undergone noise reduction processing, a noise reduction off state corresponding to the audio information, and a noise reduction intensity corresponding to the noise reduction on state (which may be regarded as noise reduction intensity of 0 at this time) can be acquired.

Further, in one embodiment of the present application, as shown in fig. 3 and 4, in the process of acquiring the multimedia information and the noise reduction information, a noise reduction icon corresponding to the noise reduction state is displayed. In this way, in the process of acquiring the multimedia information and the noise reduction information corresponding to the multimedia information, the user can clearly observe the noise reduction icon, and further determine the acquisition state at this time. Specifically, the noise reduction icons include a noise reduction off icon corresponding to a noise reduction off state, and a noise reduction on icon corresponding to a noise reduction on state.

Specifically, as shown in fig. 4, in the process of acquiring the multimedia information and the noise reduction information, if the audio information is not subjected to noise reduction processing under the first input; here, video information, audio information which has not undergone noise reduction processing, and noise reduction off state can be acquired. Further, a noise reduction off icon corresponding to the noise reduction off state and the noise reduction intensity at that time (which may be regarded as the noise reduction intensity being 0 at that time) may also be displayed.

Specifically, as shown in fig. 3, in the process of acquiring the multimedia information and the noise reduction information, if the audio information is subjected to noise reduction processing under the first input; here, video information, audio information which has not undergone noise reduction processing, and a noise reduction on state can be acquired. In addition, a noise reduction start icon corresponding to the noise reduction start state and the noise reduction intensity at that time may also be displayed.

Further, in one embodiment of the present application, as shown in fig. 5, in the process of acquiring the multimedia information and the noise reduction information, the noise reduction intensity may be adjusted, and a noise reduction intensity icon corresponding to the noise reduction intensity may be displayed. As shown in fig. 5, the noise reduction intensity may be displayed by a noise reduction intensity icon, which may be a circular icon in fig. 5. The size of the central angle corresponding to the right shadow part in the circular icon represents the percentage of the noise reduction intensity. In particular, the noise reduction intensity icon in the present application is explained by taking the annular icon as an example, and the noise reduction intensity icon defined in the present application is not limited thereto.

Further, in one embodiment of the present application, in response to the second input, the audio information that is not subjected to the noise reduction processing is subjected to the noise reduction processing according to the noise reduction intensity; and then sharing the video information stored before and the audio information subjected to the noise reduction processing. Specifically, the second input is a sharing instruction input by the user to the electronic device.

Specifically, in the process of acquiring the multimedia information and the noise reduction information, the application respectively acquires and respectively stores the multimedia information and the noise reduction information. Before sharing the multimedia information, the method synthesizes the audio information which is not subjected to noise reduction processing in the multimedia information with the noise reduction information, so as to obtain the audio information matched with the noise reduction information (when the noise reduction information is in a noise reduction closing state, the synthesizing step can be skipped); and then sharing the synthesized audio information and video information. Therefore, the multimedia information sharing method and device can realize sharing of multimedia information among different electronic devices, and further improve interestingness and convenience in the use process of the electronic devices.

Next, a method for acquiring multimedia information proposed in the present application is further explained with reference to fig. 2. As shown in fig. 2, the method for acquiring multimedia information includes:

Step 202, recording video information;

step 204, recording audio information;

step 206, identifying a noise reduction switch 1/0;1 represents noise reduction on, 0 represents noise reduction off;

step 208, storing video information in real time;

step 210, storing the non-noise-reduced audio information in real time;

step 212, save the noise reduction information in real time.

Specifically, in the process of recording multimedia information, the following three information needs to be recorded synchronously: video information, non-noise-reduced audio information, noise reduction information input by a user; the noise reduction information includes a noise reduction state and noise reduction intensity.

An embodiment of a second aspect of the present application provides a method for playing multimedia information, as shown in fig. 6, where the method for playing multimedia information includes:

step 602, respectively obtaining pre-stored multimedia information and noise reduction information in response to a third input;

step 604, playing the multimedia information, and displaying a noise reduction icon corresponding to the noise reduction information.

In the method for playing the multimedia information provided by the embodiment of the second aspect of the application, responding to the third input, and respectively acquiring the pre-stored multimedia information and the noise reduction information; and then, playing the acquired multimedia information, and displaying a noise reduction icon corresponding to the multimedia information. Specifically, the third input is a play instruction input by the user to the electronic device.

In particular, as shown in fig. 8 and 9, in the method for playing multimedia information according to the present application, when the multimedia information is played, a noise reduction icon corresponding to the multimedia information being played is displayed. Thus, the user can clearly and accurately acquire the state of the multimedia information being played at this time through the noise reduction image. For example, whether the multimedia information being played is subjected to noise reduction processing can be accurately known, and the noise reduction strength of the multimedia information being played can be accurately obtained under the condition that the multimedia information is subjected to noise reduction processing.

In addition, the multimedia information and the noise reduction information are stored in advance. Therefore, when the multimedia information is played, the user can perform corresponding noise reduction processing on the multimedia information according to the self requirements. Compared with the prior art, only the multimedia information subjected to the noise reduction treatment can be obtained, the method and the device provide a space for selecting and adjusting for the user, so that the user can play the multimedia information according to own requirements, process the multimedia information and play the corresponding multimedia information.

Further, in one embodiment of the present application, the multimedia information includes video information and audio information that has not undergone noise reduction processing; further, the noise reduction information includes a noise reduction state and noise reduction strength. In the process of acquiring the multimedia information and the noise reduction information, the video information, the audio information which is not subjected to noise reduction processing, and the noise reduction state and the noise reduction intensity corresponding to the audio information can be acquired respectively. Specifically, the noise reduction states include a noise reduction on state and a noise reduction off state.

Further, in one embodiment of the present application, as shown in fig. 9, the noise reduction state includes a noise reduction on state. In the process of playing the multimedia information and displaying the noise reduction icon corresponding to the noise reduction information, the application can perform noise reduction processing on the audio information according to the pre-stored noise reduction intensity; then, playing the audio information after noise reduction treatment; and displaying a noise reduction start icon corresponding to the noise reduction start state.

Specifically, as shown in fig. 9, in the case where the third input is a noise reduction instruction, the present application performs noise reduction processing on the audio information that has not been subjected to noise reduction processing and is stored before according to the noise reduction strength stored before; and then, playing the audio information subjected to noise reduction processing, and displaying a noise reduction start icon corresponding to the noise reduction start state while playing. Thus, when the user plays the audio information after the noise reduction processing, the user can intuitively know that the audio information at the moment has been subjected to the noise reduction processing from the noise reduction start icon, so that the user can clearly know that the audio played at the moment has been subjected to the noise reduction processing.

Further, in one embodiment of the present application, as shown in fig. 10, the noise reduction intensity previously stored is adjusted in response to a fourth input during the playing of the multimedia information. Therefore, the audio information of the audio information can be adjusted at any time in the playing process of the multimedia information, and the audio information subjected to noise reduction processing is more in accordance with the requirements of users. Specifically, the fourth input is an adjustment instruction input by the user to the electronic device.

Specifically, the user does not know the correspondence between the noise reduction intensity and the noise reduction effect, and does not know whether the reduction degree of the audio information is affected after the noise reduction processing. Therefore, before the noise reduction processing is performed on the audio information, the noise reduction strength stored before is firstly called, the noise reduction processing is performed on the audio information according to the noise reduction strength, and then the multimedia information is played. In the process of playing the multimedia information, if the audio information meets the requirements of users, the noise reduction processing is carried out on the audio information according to the noise reduction intensity. If the audio information does not meet the user requirement, at the moment, responding to a fourth input in the playing process of the multimedia information, adjusting the pre-existing noise reduction intensity, and then carrying out noise reduction processing on the audio information according to the adjusted noise reduction intensity.

The method and the device have the advantages that the noise reduction intensity can be adjusted at any time in the process of playing the multimedia information, the adjusted noise reduction intensity can be stored in real time, and the noise reduction processing is carried out on the audio information according to the adjusted noise reduction intensity. Therefore, on one hand, the user can adjust the noise reduction intensity of the audio information, and on the other hand, the user can adjust the audio information according to the real-time effect of the audio information, so that the user knows the corresponding relation between the noise reduction intensity and the noise reduction effect and the corresponding relation between the noise reduction intensity and the reduction degree.

More specifically, in the process of playing the multimedia information, the application firstly defaults to adjust the audio information according to the unregulated noise reduction intensity, and plays the audio information and the video information after noise reduction; at this time, the user may decide whether to adjust the noise reduction intensity according to the actual effect of the audio information. When the user needs to adjust the noise reduction intensity, the user can adjust the noise reduction in real time; at this time, the present application can save the noise reduction intensity after the adjustment in real time, and perform noise reduction processing on the audio information according to the noise reduction intensity after the adjustment, and play the video information and the audio information subjected to the noise reduction processing.

Furthermore, before sharing the multimedia information, the user firstly performs noise reduction processing on the audio information according to the noise reduction strength, and then shares the video information and the noise-reduced audio information. In particular, if the user does not adjust the noise reduction intensity, the noise reduction processing is performed on the audio information according to the previously stored noise reduction intensity; if the user adjusts the noise reduction intensity, the noise reduction processing is carried out on the audio information according to the adjusted noise reduction intensity.

Further, in one embodiment of the present application, as shown in fig. 10, a noise reduction intensity icon corresponding to the noise reduction intensity is displayed during the process of playing the multimedia information. That is, the user can acquire the current noise reduction intensity of the audio information from the noise reduction intensity image. Specifically, the noise reduction intensity icon is an adjustable icon (e.g., a touch icon). Thus, the user can directly adjust the noise reduction intensity of the audio information through the noise reduction intensity icon and know the noise reduction intensity of the current audio information.

Specifically, as shown in fig. 10, the noise reduction intensity icon may be a circular icon. The size of the central angle corresponding to the right shadow part in the circular icon represents the percentage of the noise reduction intensity. In particular, the noise reduction intensity icon in the present application is explained by taking the annular icon as an example, and the noise reduction intensity icon defined in the present application is not limited thereto.

Specifically, in the process of playing the multimedia information, a noise reduction on icon or a noise reduction off icon is displayed first. In the case where the noise reduction processing is performed on the audio information and the noise reduction start icon is displayed, the above-described fourth input may be input if the user needs to adjust the noise reduction intensity. At this time, in response to the fourth input, a noise reduction intensity icon corresponding to the noise reduction intensity is displayed, and the user is caused to adjust the noise reduction intensity through the noise reduction intensity icon.

Further, in one embodiment of the present application, the noise reduction state further includes a noise reduction off state. In the process of playing the multimedia information and displaying the noise reduction icon corresponding to the noise reduction information, the method and the device can directly play the audio information which is not subjected to noise reduction treatment; and displaying a noise reduction closing icon corresponding to the noise reduction closing state.

Specifically, in the case where the third input is a non-noise reduction instruction, the present application directly plays audio information that is not subjected to noise reduction processing, and displays a noise reduction closing icon corresponding to a noise reduction closing state while playing the audio information. Thus, when the user plays the audio information which is not subjected to the noise reduction processing, the user can intuitively know that the audio information at the moment is not subjected to the noise reduction processing from the noise reduction closing icon, so that the user can clearly know that the audio played at the moment is not subjected to the noise reduction processing.

Further, in one embodiment of the present application, in response to a fifth input in the playing process of the multimedia information, a noise reduction state is switched, and the audio information is processed according to the switched noise reduction state; and then, displaying the noise reduction icon corresponding to the noise reduction state in the process of playing the multimedia information. The fifth input is specifically a switching instruction of the user input to the electronic device.

Specifically, in the process of playing the multimedia information, the noise reduction closing icon can be switched to the noise reduction opening icon in response to the fifth input, and the audio information after noise reduction is played. At this time, the audio information may be switched from the non-noise reduction state to the noise reduction state, noise reduction processing may be performed on the audio information, and a noise reduction start icon may be displayed.

Specifically, during the playing of the multimedia information, the noise reduction on icon may be switched to the noise reduction off icon in response to the fifth input, and the audio information that is not noise reduced may be played. At this time, the audio information may be switched from the noise reduction state to the non-noise reduction state, without performing noise reduction processing on the audio information, and displaying a noise reduction off icon.

Further, in one embodiment of the present application, the scale of the video information is displayed at the playback interface. That is, the user can perform a zoom operation on the video information during the course of playing the video information. At this time, the playing interface line of the video information will display the corresponding scaling.

Further, in one embodiment of the present application, as shown in fig. 8, 9 and 10, a playing progress bar of the audio information is displayed on the playing interface, and during the process of playing the video information, the user may perform a fast forward or rewind operation on the video information, and may also play the video information normally. At this time, the playing interface line of the video information will display the corresponding playing progress.

Next, a method for playing the multimedia information provided in the present application is further explained with reference to fig. 7. As shown in fig. 7, the playing modes of the multimedia information include:

Step 702, obtaining video information;

step 704, playing the video information;

step 706, obtaining the audio information without noise reduction;

step 708, obtaining the noise reduction information stored before;

step 710, displaying noise reduction information;

step 712, determining whether to adjust the noise reduction information, if yes, executing step 714, otherwise executing step 716;

step 714, saving and adopting the adjusted noise reduction information;

step 716, adopting the noise reduction information stored before;

step 718, synthesizing audio information;

in step 720, the audio information is played.

Specifically, when multimedia information is played, video information and audio information without noise reduction are constant, and noise reduction information is variable. That is, the user can adjust the noise reduction information according to his own preference. Specifically, if a user manually changes the real-time noise reduction state (noise reduction on state and noise reduction off state) while playing the multimedia information, it is necessary to play the voice according to the noise reduction state after the user manually changes; and synchronously saving the noise reduction state manually changed by the user for subsequent playing. If the user needs to share the video with friends, the audio information and the noise reduction information which are not noise reduced before sharing are obtained, and the audio information which is tested to have noise reduction and is wanted by the user is obtained.

Further, as shown in fig. 10, the noise reduction information includes noise reduction intensity as well as noise reduction on state and noise reduction off state, and the user can manually select the noise reduction intensity. Specifically, under the recording interface, when a user clicks the noise reduction start icon, the noise reduction intensity icon can be displayed, the user can adjust the noise reduction intensity through the noise reduction intensity icon, and after the user selects the noise reduction intensity, the noise reduction icon can be changed. Correspondingly, the noise reduction strength can be manually adjusted by a user under the playing interface. Under the stored noise reduction intensity, the noise reduction intensity can be expressed by adopting an 8-bit 2-system number; the information of the noise reduction intensity can be directly transmitted to the inside of a recording noise reduction algorithm to control the strength of the actual noise reduction effect.

As shown in fig. 11, a third embodiment of the present application proposes an apparatus 1100 for acquiring multimedia information, including: an obtaining unit 1102, configured to obtain multimedia information and noise reduction information corresponding to the multimedia information in response to a first input; a storage unit 1104 for storing multimedia information and noise reduction information.

In the multimedia information acquiring apparatus 1100, when the acquiring unit 1102 acquires multimedia information, the acquiring unit may acquire the multimedia information and noise reduction information corresponding to the multimedia information. The application can ensure the correspondence between the multimedia information and the noise reduction information in the process of storing the multimedia information and the noise reduction information, and can ensure the correspondence between the obtained multimedia information and the noise reduction information.

In this way, when the multimedia information is played later, the user can freely select whether to perform noise reduction processing on the multimedia information, and the user is allowed to switch between noise reduction and noise non-reduction in the playing process, and even the user is allowed to switch the noise reduction intensity. Specifically, the first input is an acquisition instruction input by a user to the electronic device.

In addition, in the process of acquiring the above-mentioned multimedia information and noise reduction information by the acquiring unit 1102, the user often does not know the actual effect of the noise reduced multimedia information, which may cause that the noise reduction effect of the multimedia information does not conform to the user's expectation when the multimedia information is played later. Therefore, the method and the device respectively store the multimedia information and the noise reduction information corresponding to the multimedia information in the acquisition stage, so that a user can perform noise reduction processing on the multimedia information according to actual experience and needs in the subsequent process of playing the multimedia information, and the playing effect of the multimedia information is greatly improved.

Further, in one embodiment of the present application, the multimedia information includes video information and audio information that has not undergone noise reduction processing; and, the noise reduction information includes a noise reduction state and a noise reduction intensity.

Specifically, the noise reduction states include a noise reduction on state and a noise reduction off state.

Specifically, in the process of acquiring the multimedia information and the noise reduction information by the acquiring unit 1102, if the audio information is not subjected to noise reduction processing under the first input; here, video information, audio information which has not undergone noise reduction processing, a noise reduction off state corresponding to the audio information, and a noise reduction intensity corresponding to the noise reduction on state (which may be regarded as noise reduction intensity of 0 at this time) can be acquired.

Specifically, in the process of acquiring the multimedia information and the noise reduction information by the acquiring unit 1102, if the audio information is subjected to noise reduction processing under the first input; here, video information, audio information which has not undergone noise reduction processing, a noise reduction on state corresponding to the audio information, and noise reduction intensity corresponding to the noise reduction on state can be acquired.

Further, in an embodiment of the present application, the apparatus 1100 for obtaining multimedia information further includes a first playing unit. The first playing unit is used for displaying a noise reduction icon corresponding to the noise reduction state in the process of acquiring the multimedia information and the noise reduction information.

Before sharing the multimedia information, the method synthesizes the audio information which is not subjected to noise reduction processing in the multimedia information with the noise reduction information, so as to obtain the audio information matched with the noise reduction information (when the noise reduction information is in a noise reduction closing state, the synthesizing step can be skipped); and then sharing the synthesized audio information and video information. Therefore, the multimedia information sharing method and device can realize sharing of multimedia information among different electronic devices, and further improve interestingness and convenience in the use process of the electronic devices.

As shown in fig. 12, a fourth embodiment of the present application provides a playing device 1200 for multimedia information, including: a second processing unit 1202, configured to obtain pre-stored multimedia information and noise reduction information in response to a third input, respectively; and a second playing unit 1204 for playing the multimedia information and displaying a noise reduction icon corresponding to the noise reduction information. Specifically, the third input is a play instruction input by the user to the electronic device.

In particular, in the playback device 1200 for multimedia information according to the present application, when the multimedia information is played back, the second playback unit 1204 displays a noise reduction icon corresponding to the multimedia information being played back. Thus, the user can clearly and accurately acquire the state of the multimedia information being played at this time through the noise reduction image. For example, whether the multimedia information being played is subjected to noise reduction processing can be accurately known, and the noise reduction strength of the multimedia information being played can be accurately obtained under the condition that the multimedia information is subjected to noise reduction processing.

In addition, the multimedia information and the noise reduction information are stored in advance. In this way, when the second playing unit 1204 plays the multimedia information, the user can perform corresponding noise reduction processing on the multimedia information according to the own requirement. Compared with the prior art, only the multimedia information subjected to the noise reduction treatment can be obtained, the method and the device provide a space for selecting and adjusting for the user, so that the user can play the multimedia information according to own requirements, process the multimedia information and play the corresponding multimedia information.

Further, in one embodiment of the present application, the multimedia information includes video information and audio information that has not undergone noise reduction processing; the noise reduction information includes a noise reduction state and noise reduction intensity.

Further, in one embodiment of the present application, the noise reduction state includes a noise reduction on state. In the process of playing the multimedia information and displaying the noise reduction icon corresponding to the noise reduction information by the second playing unit 1204, the second processing unit 1202 performs noise reduction processing on the audio information according to the noise reduction intensity stored in advance; then, the second playing unit 1204 plays the audio information after the noise reduction processing; and displaying a noise reduction start icon corresponding to the noise reduction start state.

Specifically, in the case where the third input is a noise reduction instruction, the second processing unit 1202 performs noise reduction processing on the previously stored audio information which is not subjected to noise reduction processing according to the previously stored noise reduction intensity; then, the second playing unit 1204 plays the audio information after the noise reduction processing, and displays a noise reduction start icon corresponding to the noise reduction start state while playing. In this way, when the second playing unit 1204 plays the audio information after the noise reduction processing, the user can intuitively learn from the noise reduction start icon that the audio information at this time has undergone the noise reduction processing, so that the user can clearly learn that the audio played at this time has undergone the noise reduction processing.

Further, in one embodiment of the present application, the second processing unit 1202 may also adjust the previously stored noise reduction intensity in response to the fourth input. Therefore, the audio information of the audio information can be adjusted at any time in the playing process of the multimedia information, and the audio information subjected to noise reduction processing can meet the requirements of users. Specifically, the fourth input is an adjustment instruction input by the user to the electronic device.

Specifically, the user does not know the correspondence between the noise reduction intensity and the noise reduction effect, and does not know whether the reduction degree of the audio information is affected after the noise reduction processing. Therefore, before the noise reduction processing is performed on the audio information, the second processing unit 1202 first retrieves the noise reduction strength stored before, performs the noise reduction processing on the audio information according to the noise reduction strength, and then plays the multimedia information. In the process of playing the multimedia information, if the audio information already meets the user requirement, the second processing unit 1202 may perform the noise reduction processing on the audio information according to the noise reduction strength. If the audio information does not meet the user requirement, the second processing unit 1202 responds to the fourth input in the playing process of the multimedia information to adjust the pre-existing noise reduction intensity, and then the second processing unit 1202 performs noise reduction processing on the audio information according to the adjusted noise reduction intensity.

The method and the device have the advantages that in the process of playing the multimedia information, the noise reduction intensity can be adjusted at any time, the adjusted noise reduction intensity can be stored in real time, and the noise reduction processing is carried out on the audio information according to the adjusted noise reduction intensity. Therefore, on one hand, the user can adjust the noise reduction intensity of the audio information, and on the other hand, the user can adjust the audio information according to the real-time effect of the audio information, so that the user knows the corresponding relation between the noise reduction intensity and the noise reduction effect and the corresponding relation between the noise reduction intensity and the reduction degree.

Further, in an embodiment of the present application, during the process of playing the multimedia information, the second playing unit 1204 is further configured to display a noise reduction intensity icon corresponding to the noise reduction intensity. That is, the user can acquire the current noise reduction intensity of the audio information from the noise reduction intensity image. Specifically, the noise reduction intensity icon is an adjustable icon (e.g., a touch icon). Thus, the user can directly adjust the noise reduction intensity of the audio information through the noise reduction intensity icon and know the noise reduction intensity of the current audio information.

Specifically, during the process of playing the multimedia information, the second playing unit 1204 may first display a noise reduction on icon or a noise reduction off icon. In the case where the second processing unit 1202 performs noise reduction processing on the audio information and displays a noise reduction on icon, the above-described fourth input may be input if the user needs to adjust the noise reduction intensity. At this time, in response to the fourth input, the second playing unit 1204 displays a noise reduction intensity icon corresponding to the noise reduction intensity, and causes the user to adjust the noise reduction intensity through the noise reduction intensity icon.

Further, in one embodiment of the present application, the noise reduction state further includes a noise reduction off state; in the process of playing the multimedia information and displaying the noise reduction icon corresponding to the noise reduction information by the second playing unit 1204, the application can directly play the audio information which is not subjected to noise reduction processing; and displaying a noise reduction closing icon corresponding to the noise reduction closing state.

Specifically, in the case where the third input is a non-noise reduction instruction, the second playing unit 1204 directly plays the audio information that is not subjected to the noise reduction processing, and displays a noise reduction closing icon corresponding to the noise reduction closing state while playing. Thus, when the user plays the audio information which is not subjected to the noise reduction processing, the user can intuitively know that the audio information at the moment is not subjected to the noise reduction processing from the noise reduction closing icon, so that the user clearly knows that the audio played at the moment is not subjected to the noise reduction processing.

Further, in one embodiment of the present application, in response to a fifth input in the playing process of the multimedia information, a noise reduction state is switched, and the audio information is processed according to the switched noise reduction state; and then, displaying the noise reduction icon corresponding to the noise reduction state in the process of playing the multimedia information. Specifically, the fifth input is a switching instruction of the input of the electronic device by the user.

Specifically, during the playing of the multimedia information, the second playing unit 1204 may switch the noise reduction on icon to the noise reduction off icon in response to the fifth input, and play the audio information without noise reduction. At this time, the audio information may be switched from the noise reduction state to the non-noise reduction state, and the second processing unit 1202 does not perform noise reduction processing on the audio information and displays a noise reduction off icon.

Specifically, in the process of playing the multimedia information, responding to the fifth input, switching the noise reduction on icon to the noise reduction off icon, and playing the audio information which is not subjected to noise reduction processing. At this time, the audio information may be switched from the noise reduction state to the non-noise reduction state, without performing noise reduction processing on the audio information, and displaying a noise reduction off icon.

Further, in an embodiment of the present application, the second playing unit 1204 may also display a scaling of the video information. That is, the user can perform a zoom operation on the video information during the course of playing the video information. At this time, the playing interface line of the video information will display the corresponding scaling.

Further, in an embodiment of the present application, the second playing unit 1204 may further display a playing progress bar of the audio information, and in a process of playing the video information, the user may perform a fast forward or a rewind operation on the video information, and may also play the video information normally. At this time, the playing interface line of the video information will display the corresponding playing progress.
