Fig. 2 is a flowchart of a data processing method according to an embodiment of the present invention. The data processing method can be applied to any terminal. Referring to fig. 2, the embodiment includes:
201. and the terminal displays a video editing page, and the video editing page is provided with a sound effect setting control.
In the embodiment of the present invention, the video editing page is used for the terminal to play a current video to be edited and process video data, audio data, and the like included in the video to be edited, and the video to be edited may be a video recorded and stored by the terminal, and certainly may also be a video sent to the terminal by the server.

In addition, the video editing page may further have other setting controls, for example, the video editing page may further have a video special effect setting control, a music clip control, and the like.
Specifically, as shown in fig. 3, the main body of the video editing page is used for playing a video to be edited and a video that is processed, a video special effect setting control, a sound effect setting control, a music editing control, a user homepage control, and the like may be sequentially arranged above the video editing page, and a lyric switch control may be arranged below the user homepage control.

Of course, in other embodiments, the controls of the video editing page may also be distributed in other manners, and the distribution manner of the controls of the video editing page is not limited in this embodiment of the present invention.
202. And when the terminal detects the clicking operation on the sound effect setting control, skipping to a sound effect setting page.
In the embodiment of the invention, based on the video editing page, a user can click any control on the video editing page, for example, the user can click a sound effect setting control on the video editing page. When the terminal detects the clicking operation of the sound effect setting control, a page jump instruction is triggered, the page jump instruction can carry a sound effect setting page identifier, and the sound effect setting control is associated with the sound effect setting page, so that the terminal can jump to the sound effect setting page based on the page jump instruction. Wherein, this audio sets up the page and is used for handling this audio data that waits to edit the video correspondence, and then, the terminal can add the audio for this video of waiting to edit, and in addition, this audio sets up the page and can also be used for playing the video data and the audio data that add the sound completely.
203. The terminal displays a sound effect setting page, and the sound effect setting page is provided with a time axis and a plurality of sound effect controls of a video to be edited.
In the embodiment of the present invention, based on step 202, the sound effect setting page displayed by the terminal may be configured to add at least one sound effect to the audio data corresponding to the video to be edited, and for this reason, the sound effect setting page may have a plurality of operable controls, where the plurality of operable controls may include a time axis and a plurality of sound effect controls, where the time axis may be used for a user to select a start frame of an audio clip to be currently processed, each sound effect control corresponds to a sound effect type, the plurality of sound effect controls are used for the user to select a target sound effect type to be added to the audio data corresponding to the video to be edited, and the target sound effect type is a sound effect type to be added to the audio data corresponding to the video to be edited by the user.
Specifically, the sound effect setting page may be as shown in fig. 4, a main body portion in the middle of the sound effect setting page is a preview box, the preview box may be used for the terminal to play the video to be edited to which the target sound effect type is added, and a time axis and a plurality of sound effect controls may be provided below the preview box. The time axis is used for representing the audio time length of the video to be edited, the coordinate on the time axis is a time scale, and the time scale is used for representing the audio playing time point of the video to be edited. Of course, the time axis may be a line segment with a time scale mark, or may not have the time scale mark, as long as the time axis can be used to represent the audio duration of the video to be edited and the audio playing time point thereof, and the embodiment of the present invention does not limit the specific form of the time axis here.
Furthermore, in the sound effect setting page, each sound effect control is associated with one sound effect type, as shown in fig. 4, the sound effect type associated with each sound effect control may be a magic beast sound effect, a minions sound effect, a gramophone sound effect, and the like, and certainly, the sound effect type associated with each sound effect control may also be other sound effect types.
It should be noted that, in addition to the time axis and the plurality of sound effect controls, the sound effect setting page may further include other controls, as shown in fig. 4, and the sound effect setting page may further include a storage control, a volume setting control, and the like, where the storage control is configured to store processed audio data and video data, and the volume setting control is configured to adjust a volume corresponding to the video to be edited. In addition, besides the time axis and the distribution positions of the plurality of controls shown in fig. 4, the time axis and the plurality of controls may be distributed in other manners, which is not limited herein in the embodiment of the present invention.
204. The terminal determines a start frame based on a selection operation for any time on the time axis.
In this embodiment of the present invention, based on the time axis in step 203, the time axis may further have a movable pointer, where the movable pointer is used for a user to perform a selection operation on any time scale on the time axis, and further, the movable pointer is used for a terminal to indicate a start time of processing audio data corresponding to a video to be edited. Specifically, the user can arbitrarily drag the movable pointer to perform a selection operation on any time scale on the time axis, that is, the user can drag the movable pointer to any position on the time axis as required.
Further, when the user drags the movable pointer to any position on the time axis, the terminal may detect a selection operation of a time scale corresponding to the position on the time axis, and then, the terminal may use an audio frame of a position corresponding to the time scale in the audio data of the video to be edited as a start frame for processing the audio data corresponding to the video to be edited, where the start frame is an audio frame that is not subjected to sound effect processing.
In other embodiments, in addition to dragging the movable pointer to any position on the time axis to perform the selection operation at any time on the time axis, the user may perform the selection operation in other ways to determine the start frame. For example, the user may also perform a selection operation by clicking any position on the time axis, and the specific implementation manner of the selection operation is not limited herein.
It should be noted that, a user may perform a plurality of selection operations on the time scale on the time axis, that is, after the terminal detects that a selection operation is performed on the time scale on the time axis once, and the terminal completes sound processing on one audio clip in the audio data based on the start frame corresponding to the selection operation, the user may further perform a selection operation on the time scale on the time axis again to perform sound processing on other audio clips of the audio data corresponding to the video to be edited, where a sound type added to the other audio clips may be different from a sound type corresponding to the one audio clip, and may of course be the same. In addition, the audio segment and the other audio segments are not overlapped with each other.
205. And when the terminal detects the long-time pressing operation on the target control in the plurality of sound effect controls, acquiring the target sound effect type corresponding to the target control.
In embodiments of the present invention, each sound effect control is associated with a corresponding sound effect type, i.e., the target control is associated with a target sound effect type. The target control is a sound effect control selected by a user according to the requirement on the target sound effect type, the target sound effect type is the sound effect type which the user wants to add to the audio clip after the initial frame, and each sound effect control is associated with one sound effect type, so that the user can select the target sound effect type meeting the requirement by pressing the target control for a long time. Specifically, when the terminal can detect that the user presses the target control for a long time, a target sound effect type calling instruction can be triggered, and then the terminal can acquire the target sound effect type associated with the target control based on the target sound effect calling instruction.
It should be noted that, based on the long-press operation on the target control, the terminal may perform processing corresponding to the target sound effect type on the audio data of the video to be edited, that is, the long-press operation may provide an instruction for the terminal to start processing and end processing on the audio data. Specifically, when the terminal detects the long-press operation on the target control, the terminal starts to process the audio frame after the initial frame, and as long as the terminal does not detect the end of the long-press operation, the terminal continues to process the audio frame until the terminal detects the end of the long-press operation, and the terminal stops processing the audio frame.
Further, the long-time pressing operation may be implemented by a user holding the target control all the time, and the long-time pressing operation is ended when the user releases the target control, that is, as long as the user holds the target control all the time, the terminal processes the audio frame after the start frame. Of course, in other embodiments, the target control may be operated in other manners, so that the terminal triggers the start processing instruction and the end processing instruction, for example, the user may click the target control, that is, when the user clicks the target control, the terminal starts to process the audio frame after the start frame, and when the user clicks the target control again, the terminal stops processing the corresponding audio frame.
206. And the terminal performs sound changing algorithm processing on the audio frames after the starting frame based on the target sound effect type to obtain a plurality of target audio frames.
In the embodiment of the present invention, the pitch change algorithm processing refers to that the terminal processes pitch information of an audio frame, so that a tone of the audio frame changes, and then the terminal adds corresponding target audio effect types to a plurality of audio frames to obtain a plurality of corresponding target audio frames, wherein the pitch information corresponding to the plurality of target audio frames is the same as the pitch information corresponding to the target audio effect types.
Specifically, for example, in a time domain, the pitch period of the corresponding audio frame may be changed by the pitch-changing and non-speed-changing algorithm, so that the frequency spectrum of the audio frame is changed, and further, the duration corresponding to the audio frame is changed, so that the pitch information of the audio frame is the same as the pitch information corresponding to the target sound effect type, that is, the pitch-changing processing of the audio frame is realized.
Further, in the process of the above-mentioned pitch change, the corresponding speed of sound is also changed, so the terminal needs to resample the above-mentioned audio frame, so that the total length of the corresponding audio frame is not changed, to implement the constant speed processing of the audio frame, and finally, the pitch change is not performed on a plurality of audio frames after the start frame, so as to obtain a plurality of target audio frames. Of course, in other embodiments, the terminal may also use other inflexion algorithms to process a plurality of audio frames after the start frame, for example, the terminal may also perform inflexion algorithm processing on the plurality of audio frames in the frequency domain, as long as the obtained pitch information of the target audio frame is the same as the pitch information of the target sound effect type, which is not limited in this embodiment of the present invention.
The step 206 is a process of performing sound effect processing on the audio frame after the start frame by the terminal based on the target sound effect type, in other embodiments, the terminal may also perform other sound effect processing on the audio frame as long as the target sound effect type can be added to the audio frame, and the embodiment of the present invention is not limited herein.
207. And the terminal plays a plurality of target audio frames subjected to sound effect processing in real time on the sound effect setting page and synchronously plays a plurality of video frames corresponding to the plurality of target audio frames.
In the embodiment of the present invention, based on the preview box of the main body portion in fig. 4, the preview box is used for playing a plurality of video frames corresponding to the plurality of target audio frames. The preview frame plays the plurality of video frames synchronously with the playing of the plurality of target audio frames by the terminal, and the terminal plays the plurality of target audio frames in real time with the processing of the audio frame after the initial frame, that is, the terminal plays the target audio frame every time the terminal obtains one target audio frame while performing the pitch change algorithm processing on each audio frame after the initial frame.
It should be noted that, the frame length of each target audio frame is the same as the frame length of the audio frame before processing, so that the video frame corresponding to each target audio frame is the same as the video frame corresponding to the audio frame before processing, and further, when the terminal plays a plurality of target audio frames, the preview frame in the sound effect setting page may also play a plurality of video frames corresponding to the plurality of target audio frames simultaneously.
Furthermore, the time for the terminal to perform the inflexion algorithm processing on each audio frame is very short, in general, the time for the terminal to process one audio frame into a corresponding target audio frame is within 23ms, and based on the short processing time, the time difference between the playing process of the terminal on the target audio frame and the generation process of the target audio frame on the sound effect setting page can be ignored, and further, the generation process and the playing process can be performed synchronously.
208. And when the terminal detects that the long-press operation on the target control is finished, determining an end frame corresponding to the finishing time of the long-press operation.
In this embodiment of the present invention, based on step 205, when the terminal detects that the user starts to perform the long-press operation on the target control, the terminal starts to perform the audio algorithm processing on the audio frame after the start frame corresponding to the long-press operation, until the terminal detects that the long-press operation on the target control is finished through the relevant detection control, the terminal triggers the finishing processing command, and based on the finishing processing command, the terminal finishes processing the audio frame.
The terminal can take the audio frame associated with the moment as an end frame corresponding to the current target sound effect type, and the end frame can be an audio frame which is not processed by a sound effect algorithm.
In addition, the user may also cancel the processing of the terminal on the audio frame, for example, as shown in fig. 4, the audio setting page may have a cancel control, after the terminal processes a section of audio clip, the user may select whether to keep the current processing according to the requirement, if the user wants to process the audio clip again, the cancel control may be clicked, when the terminal detects the click operation on the cancel control, a cancel command is triggered, and the terminal cancels the processing of the current audio clip based on the cancel command, that is, restores the audio clip to which the target audio type is currently added.
209. The terminal combines a plurality of target audio frames between the start frame and the end frame into a target audio segment.
In the embodiment of the present invention, the start frame and the end frame are audio frames that are not processed by a sound effect algorithm, so that the terminal can obtain a target audio clip based on a plurality of target audio frames between the start frame and the end frame, where the plurality of target audio frames are audio frames processed by the sound effect algorithm. Specifically, the terminal may connect every two adjacent target audio frames in the plurality of target audio frames end to end, that is, starting from the first target audio frame after the start frame, and every time a target audio frame is obtained according to the time sequence, the terminal connects the head of the target audio frame to the tail of the last target audio frame until the last target audio frame before the end frame, so that the terminal merges the plurality of target audio frames between the start frame and the end frame into the target audio segment.
The step 209 is a process of determining, by the terminal, the target audio segment based on the start frame and the end frame, and certainly, in other embodiments, the terminal may also determine the target audio segment by other manners, which is not limited herein.
The foregoing steps 205 to 209 are processes of, when the terminal detects a long-press operation on a target control in the multiple sound-effect controls, performing sound-effect processing corresponding to a target sound-effect type with the start frame as a starting point until the long-press operation is detected to be ended, and determining a target audio segment based on an end frame corresponding to an end time of the long-press operation, where the processes are processes of, by the terminal, determining a target audio segment corresponding to the target sound-effect type based on one target sound-effect type, and certainly, after the terminal determines a target audio segment, determining other target sound-effect segments based on other target sound-effect types again based on the processes, that is, the terminal may perform the processes of the foregoing steps 204 to 209 many times based on multiple target sound-effect types to process audio data of a video to be edited into multiple target audio segments, each target audio clip may correspond to a target sound effect type, which is not limited herein in the embodiments of the present invention.
210. The terminal generates target audio data based on the target audio segment.
In the embodiment of the present invention, every two target audio segments in the plurality of target audio segments may be adjacent or may not be adjacent. Specifically, when every two target audio segments are adjacent, every two adjacent target sound effect segments can be connected end to end, so that the plurality of target audio segments are combined into target audio data; when every two target audio clips are not adjacent, the head of each target audio clip is respectively connected with the tail of the audio clip which is adjacent to the target audio clip and is not processed by the sound effect algorithm, and similarly, the tail of each target audio clip is respectively connected with the head of the audio clip which is adjacent to the target audio clip and is not processed by the sound effect algorithm, so that the target audio clips and the audio clips which are not processed by the sound effect algorithm are combined into target audio data.
After the target audio data is generated based on the above process, the target audio data may be saved in a folder of the terminal for subsequent calling, and of course, the terminal may also upload the target audio data to the server, and may subsequently obtain the target audio data from the server.
Specifically, as shown in fig. 4, the target audio data may be saved through a saving control on the sound effect setting page, when the terminal detects a click operation on the saving control, the terminal may jump to the saving page, and the user may select to store the target audio data in the local folder or upload the target audio data to the server based on the saving page. Of course, the target audio data may also be saved through other controls, and the embodiment of the present invention is not limited herein.
According to the embodiment of the invention, based on the time axis and the plurality of sound effect controls on the sound effect setting page, the plurality of target audio clips can be determined, the sectional processing of the whole audio data is realized, and further, each target audio clip can be respectively corresponding to the corresponding target sound effect type, so that at least one target sound effect can be added to the whole audio data, and the diversified requirements for the target sound effects are met.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
