Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1, an audio processing method is provided in an embodiment of the present disclosure. The audio processing method comprises the following steps:
101: during recording, storing an unprocessed first audio signal and a second audio signal processed in a preset recording mode at the same time; and
102: and when the second audio signal is determined not to meet the preset requirement, carrying out audio processing on the first audio signal so as to enable the first audio signal to meet the preset requirement.
Referring to fig. 2, an audio processing apparatus 10 is provided in the present embodiment. The audio processing device 10 comprises a memory module 11 and a processing module 12. The audio processing method according to the embodiment of the present application can be applied to the audio processing apparatus 10. The storage module 11 is configured to execute step 101, and the processing module 12 is configured to execute step 102. That is, the storage module 11 is configured to store the unprocessed first audio signal and the processed second audio signal in the preset recording mode at the same time during recording. The processing module 12 is configured to perform audio processing on the first audio signal when it is determined that the second audio signal does not meet the preset requirement, so that the first audio signal meets the preset requirement.
Referring to fig. 3, an electronic device 100 is further provided in the present embodiment. The electronic device 100 comprises a processor 30. The audio processing method of the embodiment of the application can be applied to the electronic device 100. The processor 30 is configured to perform step 101 and step 102. That is, the processor 30 is configured to store the unprocessed first audio signal and the processed second audio signal in the preset recording mode at the same time during recording; and when the second audio signal is determined not to meet the preset requirement, carrying out audio processing on the first audio signal so as to enable the first audio signal to meet the preset requirement.
The electronic device 100 further includes a housing 40. The electronic device 100 may be a cell phone, a tablet computer, a display device, a notebook computer, a teller machine, a gate, a smart watch, a head-up display device, a game console, etc. As shown in fig. 3, in the embodiment of the present application, the electronic device 100 is a mobile phone as an example for description, and it is understood that the specific form of the electronic device 100 is not limited to the mobile phone. The housing 40 may also be used to mount functional modules of the electronic device 100, such as a display device, an imaging device, a power supply device, and a communication device, so that the housing 40 provides protection for the functional modules, such as dust prevention, drop prevention, and water prevention.
Specifically, when the user uses the electronic device 100 and starts recording, the processor 30 may simultaneously store the unprocessed first audio signal and the processed second audio signal in the preset recording mode. The first audio signal is an unprocessed audio signal, that is, an original audio signal of a user when recording through the electronic device 100. The preset recording mode may be a conference mode, an interview mode, a standard mode, or the like, and thus the second audio signal is a processed audio signal obtained by setting the preset recording mode. Generally, the predetermined recording mode is a standard mode, and the second audio signal is an audio signal in the standard mode, and compared with the first audio signal, the original audio signal is subjected to noise reduction in the standard mode to obtain the second audio signal.
Next, after the processor 30 obtains the first audio signal and the second audio signal, the processor 30 needs to determine whether the second audio signal meets the preset requirement, and when the second audio signal does not meet the preset requirement, perform audio processing on the first audio signal so that the first audio signal meets the preset requirement. The preset requirement is a preset requirement of a user, and if the user wants that the environmental noise in the second audio signal after passing through the processor 30 is small, the voice is clear.
Taking the preset recording mode as the standard mode, the preset requirement is clear human voice, and no environmental noise is taken as an example, after the electronic device 100 starts recording, the processor 30 stores the first audio signal and the second audio signal, the second audio signal is recording in the standard mode, and after the recording is subjected to noise reduction processing, the second audio signal with less environmental noise is obtained. However, the processed second audio signal does not meet the requirements of clear human voice and no environmental noise, and therefore, the second audio signal does not meet the preset requirements, and at this time, the processor 30 processes the unprocessed first audio signal again, so that the processed first audio signal can meet the requirements of clear human voice and no environmental noise. If the processor 30 processes the first audio signal in the interview mode, the interview mode filters out environmental noise in the audio signal and enhances human voice, so that the first audio signal meets the preset requirement.
The audio processing method, the audio processing apparatus 10 and the electronic device 100 according to the embodiment of the present application can simultaneously store the first audio signal without being processed and the second audio signal processed in the preset recording mode during recording, and ensure that the first audio signal can be processed by performing audio processing on the first audio signal when the second audio signal does not meet the preset requirement, so that the first audio signal meets the preset requirement. From this, then can guarantee whether predetermine the recording mode and correspond preset demand, finally obtained audio signal can both accord with preset demand, and predetermine the demand and be the good demand of user preset, consequently, can guarantee that finally obtained audio signal homoenergetic satisfies user's recording demand to promote user's use and experience.
Referring to fig. 2-4, in some embodiments, step 102: audio processing a first audio signal, comprising the steps of:
401: identifying different objects in the first audio signal, the objects including human voice and ambient noise;
402: receiving a first input operation to determine an object to be adjusted and an adjustment amplitude of a parameter to be adjusted, wherein the parameter comprises noise reduction intensity and gain; and
403: and processing the first audio signal according to the object to be adjusted and the adjustment amplitude of the parameter.
In certain embodiments, the processing module 12 is further configured to perform steps 401, 402, and 403. Namely, the processing module 12 is configured to identify different objects in the first audio signal, wherein the objects include human voice and environmental noise; receiving a first input operation to determine an object to be adjusted and an adjustment amplitude of parameters to be adjusted, wherein the parameters comprise noise reduction strength and gain; and processing the first audio signal according to the object to be adjusted and the adjustment amplitude of the parameter.
In certain embodiments, processor 30 is further configured to perform steps 401, 402, and 403. I.e. the processor 30 is arranged to identify different objects in the first audio signal, the objects comprising human voice and ambient noise; receiving a first input operation to determine an object to be adjusted and an adjustment amplitude of parameters to be adjusted, wherein the parameters comprise noise reduction strength and gain; and processing the first audio signal according to the object to be adjusted and the adjustment amplitude of the parameter.
Specifically, before the processor 30 determines that the second audio signal does not meet the preset requirement to perform audio processing on the first audio signal, the processor 30 further needs to identify different objects in the first audio signal to perform different processing on the different objects. Wherein, the object comprises human voice and environmental noise. The processor 30 may perform sound enhancement processing on human voice and may also perform noise reduction processing on ambient noise.
Next, the processor 30 may determine an adjustment object and an adjustment amplitude of the parameter to be adjusted by receiving a first input operation of the user, and the processor 30 may process the first audio signal according to the adjustment object and the adjustment amplitude of the parameter to be adjusted. Wherein the adjusting parameters comprise noise reduction strength and gain.
As shown in fig. 5, the user may select the voice and the environmental noise displayed by the electronic device and adjust the selected object according to the adjustment bar 50 displayed in the electronic apparatus 100, where if the adjustment bar 50 is dragged upwards, the adjustment range is increased, and if the adjustment bar 50 is dragged downwards, the adjustment range is decreased. For example, after the user selects the voice, the user drags the adjustment bar 50 upwards, and the processor 30 gains the voice to make the voice in the first audio signal clearer. For another example, after the user selects the ambient noise, the adjustment bar 50 is dragged upwards, and the processor 30 increases the noise reduction strength of the ambient noise.
In some embodiments, the adjustment columns 50 include two, and the two adjustment columns 50 correspond to the noise reduction strength and the gain, respectively. The user can drag different adjustment bars 50 to control the adjustment amplitude of the noise reduction strength and the gain, respectively.
Therefore, the user can adjust the object in the first audio signal in a self-defined manner through the first input operation of the user, and can adjust the amplitude in a self-defined manner, so that the first audio signal which is in line with the expectation of the user is obtained, namely the satisfactory recording of the user is obtained.
Referring to fig. 2, fig. 3 and fig. 6, an audio processing method according to an embodiment of the present application, step 102: audio processing the first audio signal, further comprising the steps of:
601: receiving a second input operation to determine an audio processing direction; and
602: and carrying out audio processing on a target audio part corresponding to the audio processing direction in the first audio signal.
In certain embodiments, the processing module 12 is further configured to perform step 601 and step 602. Namely, the processing module 12 is further configured to receive a second input operation to determine an audio processing direction; and carrying out audio processing on a target audio part corresponding to the audio processing direction in the first audio signal.
In certain embodiments, processor 30 is configured to perform step 601 and step 602. That is, the processor 30 receives a second input operation to determine the audio processing direction; and carrying out audio processing on a target audio part corresponding to the audio processing direction in the first audio signal.
Specifically, before the processor 30 determines that the second audio signal does not meet the preset requirement to perform audio processing on the first audio signal, the processor 30 may further receive a second input operation of the user to determine an audio processing direction, so as to perform audio processing on a target audio portion of the first audio signal corresponding to the audio processing direction.
As shown in fig. 7, before the processor 30 performs audio processing on the first audio signal, the user may select directions displayed in the electronic device 100, such as front, rear, left, and right directions, to determine a direction in which the audio processing is required. The direction displayed in the electronic device 100 represents a direction around the user, such as a forward direction representing the front of the user, a backward direction representing the back of the user, and the like. In addition, there may be an upper direction and a lower direction, which are not described herein.
When the user selects the front direction, the processor 30 performs audio processing on the target audio part corresponding to the front direction. For another example, when the user selects the rear direction, the processor 30 processes the target audio portion corresponding to the rear direction. Also for example, in the left direction selected by the user, the processor 30 processes the target audio portion corresponding to the left direction.
Wherein the processing of the target audio portion by the processor 30 may be denoising or enhancing the target audio portion.
Therefore, the processor 30 can perform directional noise reduction on the first audio signal or directional enhancement on the human voice in the first audio signal according to the second input operation of the user.
Referring to fig. 2, 3, and 8, in some embodiments, step 602: the audio processing is carried out on the target audio part corresponding to the audio processing direction in the first audio signal, and the method further comprises the following steps:
801: receiving a third input operation to determine the adjustment amplitude of the parameters for adjustment, wherein the parameters comprise the noise reduction strength and the gain; and
802: and processing the target audio part according to the adjusting amplitude of the adjusting parameter.
In certain embodiments, the processing module 12 is configured to perform steps 801 and 802. Namely, the processing module 12 is configured to receive a third input operation to determine an adjustment amplitude of a parameter for performing adjustment, where the parameter includes noise reduction strength and gain; and processing the target audio part according to the adjusting amplitude of the adjusted parameter.
In certain embodiments, processor 30 is configured to perform steps 801 and 802. That is, the processor 30 is configured to receive a third input operation to determine an adjustment amplitude of the parameter for adjustment, where the parameter includes the noise reduction strength and the gain; and processing the target audio part according to the adjusting amplitude of the adjusted parameter.
Specifically, after the user selects the audio processing direction to be processed in the first audio signal by selecting the direction (as shown in fig. 7), that is, the user inputs the second input operation, the processor 30 further receives a third input operation of the user to determine an adjustment range of the parameter to be adjusted, and the processor 30 may process the target audio portion according to the adjustment range of the parameter. Wherein the adjusting parameters comprise noise reduction strength and gain.
More specifically, after the processor 30 receives the second input operation input by the user to determine the audio processing direction, the electronic device 100 may display the corresponding adjustment bar 50 (as shown in fig. 5), so that the user may drag the adjustment bar 50 (i.e., the third input operation) to enable the processor 30 to determine the adjustment amplitude of the parameter to be adjusted.
In some embodiments, the adjustment columns 50 include two, and the two adjustment columns 50 correspond to the noise reduction strength and the gain, respectively. The user can control the adjustment range of the noise reduction strength and the gain by dragging different adjustment bars 50.
Thus, the processor 30 can determine the noise reduction strength and the adjustment amplitude of the gain according to the third input operation of the user, so as to implement the noise reduction processing and the gain control of the target audio portion, that is, directionally perform the noise reduction processing and the human voice enhancement operation on the first audio signal.
In some embodiments, when the user inputs the second input operation to enable the processor 30 to determine the audio processing direction, the user may select an audio processing direction that is not desired to be adjusted by using the adjustment dial, and in this case, the target audio portion corresponding to the audio processing direction is the audio signal that is not desired to be adjusted by the user. Then, when the user inputs a third input operation, the processor 30 may adjust the amplitude according to the adjusted parameter to process the non-target audio portion. Such as increasing the gain of the non-target audio portion, or decreasing the noise reduction strength of the non-target audio portion.
Referring to fig. 2, 3 and 9, in some embodiments, step 601: receiving a second input operation to determine an audio processing direction, further comprising the steps of:
901: displaying a preset recording area through a display screen;

In certain embodiments, processor 30 is configured to perform steps 901, 902, and 903. Namely, the processor 30 is configured to display a preset recording area through the display screen; receiving a second input operation, and determining a selected area in the recording area; and determining the audio processing direction according to the selected area.
Specifically, in the process of determining the audio processing direction by the processor 30, the processor 30 may display a preset recording area through the display screen, and determine a selected area in the recording area according to the received second input operation, so as to determine the audio processing direction according to the selected area.
More specifically, as shown in fig. 10, a preset recording area 60 may be displayed on the display screen of the electronic device 100, and different directions, such as three directions a, B, and C, may be displayed in the recording area. For example, when the user selects the direction a in the recording area, the processor 30 may determine that the selected area in the recording area is the area in the direction a, and the processor 30 determines that the audio processing direction is the direction a. For another example, when the user selects the B direction in the recording area, the processor 30 may determine that the selected area in the recording area is the B direction area, and the processor 30 determines that the audio processing direction is the B direction. For example, when the user selects the recording area in the C direction, the processor 30 may determine that the selected recording area is the recording area in the C direction, and the processor 30 may determine that the audio processing direction is the C direction.
Next, the processor 30 may perform audio processing on the first audio signal in the direction according to the audio processing direction. Wherein, the audio processing may be to reduce noise or enhance the first audio signal corresponding to the direction.
Therefore, the processor 30 can perform directional noise reduction on the first audio signal or directional enhancement on the human voice in the first audio signal according to the second input operation of the user.
