Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so that embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The audio editing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

FIG. 1 is a schematic flowchart of an embodiment of an audio editing method provided by the present application. The audio editing method is applied to an electronic device including a screen that can be extended or retracted. As shown in Figure 1, the audio editing method includes:

S102, in the case where the waveform of the target audio is displayed on the screen, receive a first input from the user to the electronic device, where the first input is used to control the screen to stretch or shrink;

S104, in response to the first input, edit the waveform of the target audio.

S102 and S104 will be respectively described below.

In S102, the target audio may be audio in an audio file or audio in a video file.

The expandable or collapsible screen will be described below through the example of FIG. 2 .

As shown in FIG. 2, the direction of screen extension or contraction can be the positive direction of the Y axis (such as the upward direction), the negative direction of the Y axis (such as the downward direction), and the positive direction of the X axis (such as the right direction) ) or the negative direction of the X axis (such as the left direction). For example, stretch the screen in the positive direction of the Y-axis to increase the size of the screen in the direction of the Y-axis.

In S104, the waveform of the target audio can be edited according to the direction in which the screen is stretched or contracted. Among them, the direction in which the screen is stretched or contracted is different, and the way of editing the waveform of the target audio is also different. Therefore, the waveform of the target audio can be edited according to the editing method corresponding to the direction in which the screen is stretched or contracted. The editing method of the target audio waveform may be: adjusting the volume of the target audio, zooming the target audio waveform, cropping the target audio waveform, adjusting the amplitude of the target audio waveform, or adjusting the frequency of the target audio waveform.

As an example, in addition to editing the waveform of the target audio according to the direction in which the screen is stretched or contracted, the waveform of the target audio may also be edited according to at least one of the magnitude of the screen stretch or the speed of the screen stretch. For example, audio waveforms can be edited based on the direction in which the screen stretches or shrinks and how much the screen stretches.

In this embodiment of the present application, when the waveform of the target audio is displayed on the screen, if a first input for controlling the screen to expand or contract is received, the waveform of the target audio is edited. As a result, the waveform editing of the target audio is realized, the audio editing mode is enriched, and the audio editing mode is prevented from being too single.

In one or more embodiments of the present application, the target audio includes a first audio track and a second audio track. In this case, as shown in FIG. 3, S104 may include:

S1042, in response to the first input, separate the first audio waveform corresponding to the first audio track and the second audio waveform corresponding to the second audio track from the waveform of the target audio;

S1044: Display the first audio waveform and the second audio waveform on the screen after stretching or contracting, respectively.

It should be noted that, in this embodiment of the present application, the target audio includes a first audio track and a second audio track. Of course, the target audio may also include a third audio track other than the first audio track and the second audio track. In this case, in addition to separating the first audio waveform corresponding to the first audio track and the second audio waveform corresponding to the second audio track from the waveform of the target audio, a third audio waveform can also be separated from the waveform of the target audio The third audio waveform corresponding to the track.

The above-mentioned S1042 and S1044 will be described below through the example of FIG. 4 .

As shown in FIG. 4 , in the case where the audio waveform includes two tracks, for example, the two tracks are the accompaniment track and the vocal track. For another example, two audio tracks are audio tracks of two vocals, and when the screen is stretched in the positive direction of the Y-axis or the negative direction of the Y-axis, the waveforms of the two audio tracks are separated from the audio waveform.

In the embodiment of the present application, by controlling the screen to stretch or shrink, the audio waveform of each audio track can be separated from the target audio waveform, which is convenient for the user to analyze each audio track according to the audio waveform of each audio track. For example, the volume of each audio track at different time points can be analyzed according to the audio waveform of each audio track.

In one or more embodiments of the present application, after S1042, the audio editing method may further include:

The volume of the first audio track is adjusted according to the input parameters of the first input; wherein the input parameters of the first input include at least one of stretch length, shrink length, stretch speed and shrink speed.

It should be noted that, in the embodiment of the present application, the volume of the first audio track is adjusted. Of course, when the target audio includes the second audio track, the volume of the second audio track can also be adjusted according to the input parameters of the first input.

As an example, in the case of adjusting the volume level of the first audio track and the volume level of the second audio track, the adjustment range of the volume level between the first audio track and the second audio track may be inconsistent.

In the embodiment of the present application, when the audio waveform of the first audio track is separated from the waveform of the target audio, the volume of the first audio track can be adjusted according to the expansion and contraction range or the expansion speed of the screen, thereby satisfying the The user needs to adjust the volume of a single track in the target audio.

In one or more embodiments of the present application, adjusting the volume of the first audio track according to the input parameters of the first input may include:

Determine the first volume adjustment range of the first audio track according to the preset relationship between the volume adjustment range of the first audio track and the input parameter;

The volume of the first audio track is adjusted according to the first volume adjustment range, wherein the adjustment range of the volume of the first audio track is the first volume adjustment range.

In the case of adjusting the volume of the second audio track, similar to adjusting the volume of the first audio track, the volume of the second audio track can be adjusted, and the adjustment range of the volume of the second audio track is the second volume adjustment magnitude.

As an example, the volume level of one of the first audio track and the second audio track can be turned up, and the volume level of the other audio track can be turned down.

The audio track whose volume is turned down and the audio track whose volume is turned up in the first audio track and the second audio track can be determined according to the direction in which the screen is extended or retracted.

The following describes how to separate the audio track and adjust the volume of the audio track by taking the first audio track as the vocal track and the second audio track as the accompaniment audio track as an example.

As an example, as shown in FIG. 5 , in the case where the direction of screen expansion or contraction is the positive direction of the Y axis, the accompaniment waveform 202 and the vocal waveform 204 are separated.

For the accompaniment track corresponding to the accompaniment waveform 202, the preset relationship between the volume adjustment range of the accompaniment track and the input parameter (the input parameter includes the telescopic speed and the telescopic length of the screen) can be the functional relationship of the following formula (1):

vol _m = γ*a*b (1)

For the vocal track corresponding to the vocal waveform 204, the preset relationship between the volume adjustment range of the vocal track and the input parameter can be the functional relationship of the following formula (2):

vol _v = (1-γ)*a*b (2)

In the above formulas (1) and (2), vol _m represents the volume adjustment range of the accompaniment track, vol _v represents the volume adjustment range of the vocal track, a represents the expansion and contraction speed of the screen, b represents the expansion and contraction length of the screen, γ is a preset coefficient, γ is between 0 and 1. The stretching speed is the stretching speed or the shrinking speed, and the stretching length may be the stretching length or the shrinking length.

After obtaining the volume adjustment range of the accompaniment track and the volume adjustment range of the vocal track, you can increase the volume of the accompaniment track according to the volume adjustment range of the accompaniment track. The volume of the vocal track is turned down.

Continuing to refer to FIG. 5 , it can be seen from the waveform changes in (a), (b) and (c) of As it increases gradually, the volume of the vocal track corresponding to the vocal waveform 204 gradually decreases. Wherein, when the screen is stretched to the maximum size, the volume of the vocal track corresponding to the vocal waveform 204 is reduced to zero, that is, the vocal is muted.

As another example, as shown in FIG. 6 , in the case where the direction of screen expansion or contraction is the negative direction of the Y axis, the accompaniment waveform 202 and the vocal waveform 204 are separated.

For the accompaniment track corresponding to the accompaniment waveform 202, the preset relationship between the volume adjustment range of the accompaniment track and the input parameter (the input parameter includes the screen's telescopic speed and telescopic length) can be the function shown in the following formula (3) relation:

vol _m = (1-γ)*a*b (3)

For the vocal track corresponding to the vocal waveform 204, the preset relationship between the volume adjustment range of the vocal track and the input parameter can be the functional relationship shown in the following formula (4):

vol _v = γ*a*b (4)

In the above formulas (3) and (4), vol _m represents the volume adjustment range of the accompaniment track, vol _v represents the volume adjustment range of the vocal track, a represents the expansion and contraction speed of the screen, b represents the expansion and contraction length of the screen, γ is a preset coefficient, γ is between 0 and 1.

After obtaining the volume adjustment range of the accompaniment track and the volume adjustment range of the vocal track, the volume in the accompaniment waveform 202 can be reduced according to the volume adjustment range of the accompaniment track, and the vocal volume can be increased according to the volume adjustment range of the vocal track Volume in waveform 204 .

Continuing to refer to FIG. 6 , it can be seen from the waveform changes in (a), (b) and (c) of FIG. 6 that as the screen stretches in the negative direction of the Y-axis, the As the volume gradually decreases, the volume of the vocal track corresponding to the vocal waveform 204 gradually decreases. When the screen is stretched to its maximum, the volume in the accompaniment waveform 202 is reduced to zero, ie the accompaniment is muted.

In an optional embodiment, adjusting the volume of the first audio track and the volume of the second audio track includes:

Determine the target volume ratio corresponding to the input parameter of the first input according to the preset relationship between the input parameter and the volume ratio;

Adjust the volume ratio between the first audio track and the second audio track to the target volume ratio.

The embodiment of the present application will be described below by taking the input parameter as the telescopic speed of the screen as an example.

Assume that the preset relationship between the telescopic speed of the screen and the volume ratio is the relationship in Table 1 below:

Table 1

screen scaling speed The volume ratio of the first track to the second track V1 M1 V2 M2 V3 M3

Wherein, M1, M2 and M3 are all values between 0 and 1.

And suppose that when the first input is received, the shrinking speed of the screen is V0. In this case, if the contraction speed V0 has the smallest difference from V1 among the three preset speeds V1, V2, V3, then M1 corresponding to V1 is determined as the target volume ratio. Then, adjust the ratio between the volume levels of the first audio track and the second audio track to M1.

The way to adjust the volume in the waveforms of the above two audio tracks when the input parameter is the stretch length of the screen is similar to the way to adjust the volume in the waveforms of the above two audio tracks when the input parameter is the stretch speed of the screen , which will not be repeated here.

In one or more embodiments of the present application, before receiving the user's first input to the electronic device, the audio editing method may further include:

receiving a second input for selecting the target fiducial point in the audio waveform;

In response to the second input, the target fiducial point is displayed on the audio waveform.

S104 may include:

The embodiments of the present application are described below by using the example of FIG. 7 .

As shown in FIG. 7 , the second input of selecting the target reference point 206 in the waveform of the target audio is first received, and then the target reference point 206 is displayed on the waveform of the target audio. Then, receiving the first input of extending the screen along the positive direction of the X axis, and taking the target reference point 206 as the center, the waveform of the target audio is enlarged and displayed.

Of course, after the target reference point 206 is displayed on the waveform of the target audio, if the first input of extending the screen in the opposite direction of the X-axis is received, the waveform of the target audio can be displayed in a reduced size with the target reference point 206 as the center.

In this embodiment of the present application, the waveform of the target audio can be amplified, so as to facilitate the user to process the waveform of the target audio. In addition, the waveform of the target audio can also be reduced, so that it is convenient for the user to view the overall fluctuation of the waveform of the target audio.

In an optional embodiment, before receiving the user's first input to the electronic device, the audio editing method may further include:

receive a third input of the target waveform segment selected in the audio waveform;

In response to the third input, the display target waveform segment is selected.

It should be noted that when the target waveform segment is selected, the target waveform segment can be displayed in the entire screen area.

As an example, after the target waveform segment is in the selected state, when an input to the target position in the target waveform segment is received, and a first input to shrink the screen to the target position in the target waveform segment is received, the target waveform Waveform segments after the target position in the segment are deleted.

As another example, the horizontal axis of the audio waveform represents time, and the vertical axis represents amplitude. After the target waveform segment is selected, the target waveform segment is deleted from the waveform of the target audio when the first input is received. Among them, the amplitude of both endpoints of the target waveform segment is zero. Therefore, it can be ensured that the target waveform segment is a segment of a complete sound, for example, the target waveform segment is a speech segment of a complete sentence, so that the sound loss of the audio waveform can be minimized.

The third input for receiving the target waveform segment selected in the audio waveform is exemplarily described below.

As an example, receiving the third input of selecting the target waveform segment in the audio waveform may include: respectively receiving the third input of selecting two points in the audio waveform, and the waveform segment between the two points is the target waveform segment.

As another example, receiving a third input of selecting a target waveform segment in the audio waveform may include receiving a third input of selecting a point in the audio waveform, and the waveform segment after the point is the target waveform segment.

As can be seen from the above two examples, the user can first select one or two points in the audio waveform, and when the user's first input is received, if two points have been selected in the audio waveform, the two The waveform segment between the points is determined as the target waveform segment. If a point has been selected in the audio waveform, the waveform segment after that point is determined as the target waveform segment.

In this embodiment of the present application, the user can select a target waveform segment in the audio waveform according to his own requirements, and then edit the target waveform segment, so as to meet the user's requirement for editing a local waveform segment in the audio waveform.
