It is to be understood that, in the case that the multimedia file is a video file, the audio file in the multimedia file is an audio file in the video file (for example, background music or human voice, etc.), and in the case that the multimedia file is an audio file, the audio file in the multimedia file is the audio file.
In the embodiment of the present application, the target noise characteristics may include: white noise, gaussian noise, impulse noise, human voice or other noise, which is not limited in the embodiments of the present application.
It should be noted that the noise characteristics in the embodiments of the present application may be understood as a noise type.
Optionally, in this embodiment of the present application, the target noise feature may be a noise feature corresponding to a shooting scene, and may also be a noise feature corresponding to a noise reduction degree, which is not limited in this embodiment of the present application.

It should be noted that the shooting scene in the embodiment of the present application includes, but is not limited to, the scene in fig. 6 described above, which may be specifically defined according to actual requirements, and this is not limited in the embodiment of the present application.
For example, in the case that the shooting scene is a seaside, the target noise feature may be a wave sound or other sounds besides the wave sound; in the case that the shooting scene is a concert, the target noise feature may be background music, or other sounds besides the background music and the singer's voice, which may be specifically set according to actual requirements, and this is not limited in the embodiment of the present application.
In the embodiment of the present application, the above-mentioned noise reduction degree refers to a degree of suppressing noise, that is, suppressing all or part of noise. For example, the noise reduction degree may be classified as high, medium, or low, the audio playing device determines that the noise reduction degree is high, and may suppress all the noise, the audio playing device determines that the noise reduction degree is medium, and may suppress 50% of the noise, and the audio playing device determines that the noise reduction degree is low, and may suppress 10% of the noise, which may be specifically set according to actual requirements, and this is not limited in this embodiment of the present application.
In one example, in the case that the audio playing device plays an audio file in the multimedia file, the audio playing device may be triggered by the user to determine the target noise characteristic, in addition to automatically determining the target noise characteristic.
Step 202: and the audio playing device determines the first audio in the audio file according to the target noise characteristics.
Optionally, in this embodiment of the application, the first audio may be: target human voice or ambient sound.
Illustratively, the environmental sounds may include: background music, sound of waves, whistling sounds or other sounds in the audio file than the target person, etc.
In example 1, the audio file includes a sea wave sound and a human voice, and the audio playing device determines that the target noise characteristic is the sea wave sound, and then the audio playing device may determine that the first audio is the human voice according to the sea wave sound.
Example 2, the audio file includes a sea wave sound and a human voice, and the audio playing device determines that the target noise feature is the sea wave sound, and then the audio playing device may determine that the first audio is the sea wave sound according to the sea wave sound.
Example 3, the audio file includes a sea wave sound and a human sound, and the audio playing device determines that the target noise feature is the human sound, and then the audio playing device may determine that the first audio is the sea wave sound according to the human sound.
Example 4, the audio file includes a sea wave sound and a human voice, and the audio playing device determines that the target noise feature is the human voice, and then the audio playing device may determine that the first audio is the human voice according to the human voice.
Step 203: and the audio playing device extracts the target audio in the audio file according to the first audio and plays the target audio.
The target audio is a first audio or a second audio, and the second audio is an audio in the audio file except the first audio.
It should be noted that, there is no obvious sequence between the audio playing apparatus extracting the target audio in the audio file and playing the target audio, for example, the audio playing apparatus plays the target audio after extracting the target audio in the audio file, or may play the target audio while extracting the target audio in the audio file, which is not limited in this application.
Illustratively, the second audio may be: target human voice or ambient sound. Specifically, the first audio may be an environmental sound when the second audio is the target voice, and the first audio may be the target voice when the second audio is the environmental sound, which is specifically set according to actual requirements.
Example 1, an audio playback apparatus extracts a first audio in an audio file as a target audio.
For example, the audio file includes a sea wave sound and a human sound, and the user needs to acquire an audio that only includes the human sound (i.e., the target audio described above), and may trigger the audio playing device to determine that the target noise feature is the sea wave sound, and then the audio playing device may determine that the first audio is the human sound according to the sea wave sound, and extract the human sound.
Example 2, the audio playing apparatus extracts the second audio in the audio file as the target audio.
For example, the audio file includes a sea wave sound and a human sound, the user needs to acquire an audio that only includes the human sound (i.e., the target audio), and may trigger the audio playing device to determine that the target noise feature is the sea wave sound, and then the audio playing device may determine that the first audio is the sea wave sound according to the sea wave sound, and extract the human sound (i.e., the second audio) from the audio file that includes the sea wave sound and the human sound according to the sea wave sound.
In one example, the audio playback device may extract the target audio in the audio file according to an AI noise reduction model.
The audio playing device can train an AI noise reduction model according to training samples in a training sample library, wherein the training sample library comprises at least one training sample, and if the extracted target audio in the audio file is human voice, each training sample in the at least one training sample contains the human voice; if the target audio in the extracted audio file is an environmental sound, each training sample in the at least one training sample comprises the environmental sound. For example, if the target audio in the extracted audio file is a sound of a sea wave, each training sample in the at least one training sample includes the sound of the sea wave; if the target audio in the extracted audio file is whistling, each training sample in the at least one training sample comprises whistling.
For example, in the case that the target audio is the second audio, the playing device extracts the target audio in the audio file according to the first audio, and the target audio can be extracted in at least two possible ways.
And 5, the audio playing device determines the second audio according to the first audio, and directly extracts the second audio from the audio file. For example, the audio playing apparatus may extract the second audio through the first AI noise reduction model.
And 6, the audio playing device extracts the first audio from the audio file according to the first audio, and then filters the first audio from the audio file to extract the second audio. For example, the audio playing apparatus may extract the first audio through the second AI noise reduction model and filter the first audio from the audio file to extract the second audio.
It should be noted that after the audio playing device extracts the target audio in the audio file, the target audio can be saved, and the target audio can be used for audio synthesis in subsequent shooting, so that a better shooting effect is achieved.
According to the audio playing method provided by the embodiment of the application, the audio playing device can determine the target noise characteristics under the condition of playing the audio file in the multimedia file. Then, the audio playing device may determine the first audio in the audio file according to the target noise characteristic. Then, the audio playing device can extract the target audio in the audio file according to the first audio and play the target audio; the target audio is a first audio or a second audio, and the second audio is an audio in the audio file except the first audio. Through the above scheme, firstly, under the condition that the audio playing device plays the audio file, the audio playing device can determine the target noise characteristic corresponding to the audio file. When the audio playing device determines the target noise characteristic, the first audio in the audio file can be accurately determined according to the target noise characteristic. Secondly, the audio playing device can extract the target audio in the audio file according to the first audio, and the accuracy of extracting the target audio in the audio file is improved due to the improvement of the accuracy rate of determining the first audio, so that the audio playing device can accurately inhibit the noise in the audio file, and the playing effect of the audio file required by a user is obtained. Therefore, the purpose of improving the playing effect of the audio file is achieved.
Optionally, in this embodiment of the present application, the audio playing apparatus may correspond to a plurality of noise characteristics, and the user selects the noise characteristics that the user wants to trigger the audio playing apparatus to determine.
For example, the step 201 may specifically include the following steps 201a to 201 d:
step 201 a: the audio playing device receives a first input of a user under the condition of playing an audio file in the multimedia file.
The first input may be a click input of a user on a screen of the audio playing device, or a voice instruction input by the user, or a specific gesture input by the user, which may be determined specifically according to an actual use requirement, and the embodiment of the present application does not limit this.
The specific gesture in the embodiment of the application can be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure identification gesture, a long-press gesture, an area change gesture, a double-press gesture and a double-click gesture; the click input in the embodiment of the application can be click input, double-click input, click input of any number of times and the like, and can also be long-time press input or short-time press input.
In one example, the click input of the user on the screen of the audio playing device may specifically be: clicking input by the user on the target control on the screen.
It should be noted that the target control may be an existing control or an additional control, which is not limited in this embodiment of the application. Wherein the target control may include at least one of: physical keys (also called physical keys or mechanical keys), virtual keys.
Specifically, the first input may be input that the user clicks the target control for a first preset duration.
For example, the first input may be a user pressing a power key, a volume key, an added Artificial Intelligence (AI) key, and the like. Specifically, the first input may be that the user presses the power key and the AI key for 3 seconds, or the first input may be that the user presses the volume key "+" and the volume key "-" once, respectively.
Step 201 b: in response to the first input, the audio playback device displays M options.
The M options correspond to M noise reduction models, and noise characteristics of the noise reduction models are different.
For example, the audio playing apparatus may display M options in the multimedia playing interface, or may display M options in the first interface, which is not limited in this embodiment of the application. The first interface may be an existing interface or a newly added interface, which is not limited in the embodiment of the present application.
For example, the first interface may be a window or a menu bar, which is not limited in the embodiment of the present application.
For example, the M noise reduction models may correspond to the same function or different functions, which is not limited in this embodiment of the application.
For example, the functions corresponding to the M noise reduction models are human voice enhancement, or the functions corresponding to the M noise reduction models are human voice suppression, or the function corresponding to at least one of the M noise reduction models is human voice enhancement, and the functions corresponding to the noise reduction models other than the at least one of the M noise reduction models are human voice suppression.
Step 201 c: and the audio playing device receives a second input of the target option in the M options from the user.
For example, the second input may be a click input of the target option by the user, or a voice instruction input by the user, or a specific gesture input by the user, which may be determined according to actual use requirements, and is not limited in this embodiment of the application.
Step 201 d: in response to the second input, the audio playing device determines a target noise reduction model corresponding to the target option, and determines the target noise characteristics according to the target noise reduction model.
For example, there is a one-to-one correspondence between the noise reduction model and the noise characteristics, and after the audio playing apparatus determines the target noise reduction model, the audio playing apparatus may determine the target noise characteristics according to the correspondence.
It should be noted that the correspondence relationship may be preset by a system or set by a user, and this is not limited in the embodiment of the present application.
For example, taking the audio playing device as a mobile phone and the video 1 is the song and the sea wave of the user a photographed at sea as an example, as shown in fig. 2, in the case that the mobile phone displays the playing interface 31 of the video 1 and plays the video 1, if the mobile phone user wants to obtain the audio only containing the song of the user a, first, the mobile phone user may click the "AI noise reduction" control 32 (i.e. the first input). At this time, as shown in fig. 3, the mobile phone displays a window 33 (i.e., the first interface) in the playback interface 31 in an overlapping manner. The window 33 displays 5 options corresponding to the 5 shooting scenes, which are respectively an "outdoor" option, a "concert" option, a "seaside" option 34, a "public transport" option, and a "home" option. The user of the handset may then click on the "seaside" option 34 (i.e. the second input described above). Then, the mobile phone determines an AI noise reduction model a, wherein the target noise feature corresponding to the noise reduction model a is the sound of the sea, and then the mobile phone may determine the first audio as the singing sound of the user a according to the sound of the sea, and extract the singing sound of the user a according to the AI noise reduction model a.
It should be noted that, when the audio playing device starts the specific application program, the audio playing device may automatically display the "AI denoising" control for the user to select whether to start the denoising function, the audio playing device displays the "AI denoising" control for a second preset time (for example, 3 seconds), and the audio playing device may cancel displaying the "AI denoising" control. When a user needs the audio playing device to display the AI noise reduction control, the audio playing device can be triggered to display the AI noise reduction control through sliding input on a screen of the audio playing device.
The specific application program may include a "camera" application program, a "recording" application program, or the like, a chat application program with a video shooting function, or a shopping application program with a video playing function, or the like. The user's sliding input on the screen may be: the user slides to the left on the screen, or slides to the right on the screen, or slides up on the screen, or slides down on the screen, which is not limited in the embodiment of the present application.
The audio playing method provided by the embodiment of the application can be applied to a scene of noise characteristics determined by selecting the options, when a user wants to improve the playing effect of an audio file, the audio playing device can be triggered to display M options according to requirements under the condition that the audio playing device plays the audio file, the user selects a corresponding noise reduction model according to requirements, and the audio playing device can determine target noise characteristics according to the target noise reduction model, so that the accuracy of the audio playing device in suppressing noise in the audio file can be improved, and the flexibility of the audio playing device in reducing noise of the audio can be improved.
Further, in this embodiment of the application, in a case that the M options correspond to the same function, before the audio playing device displays the M options, the audio playing device may further display at least two function options, and a user selects a function to be implemented first and then selects a corresponding noise reduction model.
In an example, the step 201b may specifically include the following steps 201b1 to 201b 3:
step 201b 1: in response to the first input, the audio playing device displays N function options.
Wherein, each function option corresponds to different functions, and N is a positive integer.
Step 201b 2: and the audio playing device receives a third input of the target function option in the N function options from the user.
For example, the second input may be a click input of the target function option by the user, or a voice instruction input by the user, or a specific gesture input by the user, which may be determined according to actual usage requirements, and is not limited in this embodiment of the application.
Step 201b 3: in response to the third input, the audio playback device displays M options.
Example 7, in conjunction with fig. 2, after the user of the mobile phone clicks the "AI noise reduction" control 31 (i.e. the first input mentioned above). As shown in fig. 4, 2 function options are displayed in the screen of the mobile phone, namely a "voice enhancement" function option 41 and a "voice suppression" function option 42. If the user of the mobile phone wants to obtain the audio only including the song sound of the user a, the user can click the "human sound enhancement" function option 41, at this time, as shown in fig. 3, the mobile phone displays 5 options corresponding to 5 shooting scenes in the window 33, which are respectively an "outdoor" option, a "concert" option, a "seaside" option 34, a "bus" option, and a "home" option.
Example 8, in conjunction with fig. 2, after the user of the mobile phone clicks the "AI noise reduction" control 31 (i.e. the first input mentioned above). As shown in fig. 4, 2 function options are displayed in the screen of the mobile phone, namely a "voice enhancement" function option 41 and a "voice suppression" function option 42. If the user of the mobile phone wants to obtain the audio only including the sound of the sea, the user of the mobile phone may click the "voice suppression" function option 42, and at this time, as shown in fig. 5, the mobile phone displays 3 options corresponding to 3 noise reduction degrees in the window 51, which are respectively the "high" option 52, the "medium" option, and the "low" option 53. If the phone user wants to suppress user a's singing slightly, the phone user may click the "low" option 53; if the phone user wants to suppress user a's singing completely, the phone user can click on the "high" option 52 and the phone only retains the sound of the ocean waves in video 1.
The audio playing method provided by the embodiment of the application can be applied to a scene of a function determined by selecting the function options, and the audio playing device can select the corresponding function according to the requirement by displaying the N function options, so that the corresponding noise reduction model is selected according to the M options corresponding to the function, therefore, the accuracy of selecting the noise reduction model by the user can be improved, and the flexibility of the audio playing device in audio noise reduction is also improved.
Alternatively, in this embodiment of the application, in a case where the target noise feature is a noise feature corresponding to a noise reduction degree, the audio playing apparatus may extract the target audio by the determined noise reduction degree.
In an example, the extracting the target audio in the audio file according to the first audio in step 203 may specifically include the following step 203 a:
step 203 a: the audio playing device filters out part or all of the first audio from the audio file to obtain a second audio in the audio file.
Example 1, in the case that the first audio is the target human voice, the audio playing apparatus filters part or all of the target human voice from the audio file to obtain the second audio in the audio file, that is, performs human voice suppression on the audio file.
Example 2, in the case that the first audio is an environmental sound, the audio playing apparatus filters out a part or all of the environmental sound from the audio file to obtain a second audio in the audio file, that is, performs human voice enhancement on the audio file.
In another example, the audio playback device extracts all or a portion of the first audio from the audio file.
The audio playing method in the embodiment of the application can be applied to a scene of obtaining target audios with different noise reduction degrees, and the audio playing device can flexibly obtain the target audios with different noise reduction degrees according to the requirements of a user, so that the flexibility of audio playing is improved.
