Detailed Description
The present invention provides a background music processing method and an electronic device based on artificial intelligence, and the following further describes the present invention in detail in order to make the purpose, technical scheme and effect of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a background music processing method based on artificial intelligence includes the steps of:
s1, adding external music to a background music editing interface in advance;
and S2, selecting one or more musical instruments in the background music editing interface to edit the external music to obtain background music.
By the method provided by the invention, the user can edit the background music quickly and individually. Moreover, the method provided by the invention is simple and easy to operate, so that the method is suitable for users at all ages, and even children can edit and obtain beautiful and vivid background music by the method provided by the invention.
In step S1, the external music is a music file. The format of the music file is not limited, and may be a music file in a format such as MP3, WAV, WMA, or the like. External music is imported through an import key (virtual key) in the background music editing interface, specifically, music files in a computer can be selected, and music files in a mobile U disk and a mobile hard disk connected with the computer can also be selected.
Preferably, the steps S1 and S2 include:
and converting the format of the external music into an MP3 format through the background music editing interface.
Since the files in the MP3 format have the characteristics of easy editing and easy processing, the files can be better edited by converting the external music into the MP3 format. For example, if the format of the imported external music is WAV, the external music is converted into MP3 format through the "convert" key in the background music editing interface; the format of the imported external music is WMA, and the external music is converted into the MP3 format through a "convert" key in the background music editing interface. Of course, if the music format of the external music is the MP3 format, the conversion process is not required.
Preferably, the method further comprises, after the step S1 and before the step S2, the steps of:
and defining a starting time and an ending time in advance, and cutting the external music according to the starting time and the ending time to obtain cut music fragments.
The start time specifically represents a start clipping time and the end time specifically represents an end clipping time. For example, a start time is defined as 1min, an end time is defined as 3min, when the duration of the external music is 5min, then the cutting is started at 1min of the external music and the cutting is ended at 3min, resulting in a music cut segment of 2min duration. In this way, the start time and the end time can be freely selected, so that the optimal music clip is obtained, and better background music can be edited.
Note that, when the end time is longer than the time length of the external music, the play end time of the external music is set as the end cut time in the present invention. For example, a start time is defined as 1min, an end time is defined as 5min, when the duration of the external music is 3min, then the cutting is started at 1min of the external music and the cutting is ended at 3min, resulting in a music cut segment of 2min duration. The clip music may be a part of the external music or may be the entire external music. When the cut music is represented by complete external music, the start time is the play start time of the external music, and the end time is the play end time of the external music.
Preferably, the method further comprises, after the step S1 and before the step S2, the steps of:
calling a recording device through the background music editing interface;
recording the recording music clips through the recording equipment.
The recording equipment (radio equipment) is specifically one or two of a recorder and a microphone. Taking the microphone as an example, when a user needs to input own voice or the voice of other articles, the recording device is called through the background music editing interface, the microphone is selected, and then the voice of the user or the voice of the articles is recorded through the microphone and stored as a recording music fragment. Therefore, the user can blend own and/or external sound into the background music, so that the background music has more personalized characteristics.
In step S2, one or more musical instruments in the background music editing interface are selected to edit the clip music piece and the recording music piece. The specific editing steps and how to edit will be described in detail later. Therefore, music of musical instruments can be added on the basis of external music, and background music required by the music can be edited.
Preferably, the method further comprises, after the step S1 and before the step S2, the steps of:
and selecting one or more recording fragments to be mixed with one or more cutting music fragments to obtain mixed music fragments.
The user can edit the cut music clips directly through the background music editing interface, and can also edit the recorded music clips through the background music editing interface.
Another preferable scheme of the present invention is to mix the two to obtain a mixed music piece, and then edit the mixed music piece through the background music editing interface. For example, the clipped music pieces specifically include a clipped music a, a clipped music b, a clipped music c, and a clipped music d, and the recorded music pieces specifically include a recorded music piece e, a recorded music piece f, and a recorded music piece g, so that the user may select to mix the clipped music a and the recorded music e to obtain a mixed music piece h; or selecting the cutting music fragment a, the cutting music fragment b and the recording music fragment e to mix to obtain a mixed music fragment i; of course, the cut music piece a, the cut music piece b, the cut music piece c, the cut music piece d, the recording music piece e, the recording music piece f, and the recording music piece g may be mixed to obtain the mixed music piece j. Therefore, the sound of the user can be combined with the music file for editing, and a plurality of modes for editing the background music are provided for the user.
Preferably, the step S2 specifically includes:
s21, predefining a time interval, and dividing the external music into one or more external music pieces according to the time interval;
and S22, selecting one or more corresponding musical instruments to edit the external music pieces to obtain background music.
In step S21, the time interval may be 1min, 3min, 5min, or the like. For example, the time interval is 1min, when external music with the time interval of 5min is segmented, 5 external music pieces are obtained, and the time intervals of the 5 external music pieces are all 1 min; the time interval is 3min, when external music with the time interval of 5min is segmented, 2 external music segments are obtained, and the time intervals of the 2 external music segments are 3min and 2min respectively; the time interval is 5min, and when external music with the time interval of 5min is segmented, 1 external music segment is obtained, and the time interval of the external music segment is 5 min. That is, the duration interval may be directly the duration of the external music, and when the duration interval is the duration of the external music, the external music piece is the whole piece of external music.
Of course, the external music pieces may be obtained by dividing the clip music pieces, the recording music pieces, or the mixing music pieces according to the time length intervals.
In step S22, one or more musical instruments are selected through the background music editing interface, then musical instrument music pieces are edited through the selected musical instruments, and then the musical instrument music pieces are fused with the external music pieces to obtain background music. For example, selecting a guitar and a piano to edit to obtain a musical instrument music piece a, and then fusing the musical instrument music piece a with an external music piece b to obtain background music A; for another example, selecting guitar, piano, violin, music box, drum, bamboo flute and saxophone to edit to obtain musical instrument music piece c, and then fusing the musical instrument music piece c with external music piece B to obtain background music B. Thus, the external music piece can be edited, and the background music can be obtained.
Preferably, the step S22 specifically includes:
s221, selecting two or more external music pieces to be combined to obtain combined music pieces;
s222, selecting one or more corresponding musical instruments to edit the combined music piece to obtain background music.
In step S221, the user segments the external music to obtain a plurality of external music pieces. The user can select one or more music pieces to be combined according to the requirement to obtain the combined music piece. For example, after the user divides the external music, an external music piece a, an external music piece b and an external music piece c are obtained, and the external music piece a and the external music piece c are selected to be combined to obtain a combined music piece s; it is also possible to select the external music piece b and the external music piece c to be combined, resulting in a combined music piece y.
In step S222, the user may edit the combined music piece to obtain background music. For example, selecting a piano and a violin to edit to obtain an instrument music piece a, and then fusing the instrument music piece a and the combined music piece s to obtain background music C; for another example, selecting guitar, piano, violin, music box, drum, bamboo flute and saxophone to edit to obtain musical instrument music piece b, and then fusing musical instrument music piece b with combined music piece y to obtain background music D.
The invention not only can combine external music fragments, but also can directly select a plurality of external music to be directly combined to obtain combined music, and then select one or more corresponding musical instruments to edit the combined music to obtain background music. The specific editing method has been described in detail in the above steps, and thus is not described in detail here.
Preferably, the user may also define a fusion start time and a fusion end time. For example, if the duration of the musical instrument music piece a is 1min, the duration of the external music b is 5min, the fusion start time is 3min, and the fusion end time is 4min, then the musical instrument music piece a will start to fuse in the third minute of the external music b and end to fuse in the fourth minute of the external music b.
In the above mode, the musical instrument music pieces and the external music can be fused according to the requirements of the user, so that various background music can be obtained.
Preferably, the step S2 is followed by the step of:
and S3, uploading the background music to a material library or outputting the background music to a mobile storage device.
In step S3, the user may upload the background music edited in step S2 to the material library. The material library specifically represents a server capable of storing background music, and a user can download the background music through the material library. The mobile storage device is specifically a mobile storage device such as a mobile U disk, a mobile hard disk, an optical disk and the like. Thus, the background music can be saved and recalled.
Preferably, the back music editing interface is further provided with a tutorial module.
An official (particularly a developer carrying a video music editing interface) can upload an editing course about background music, so that the official can better help a user to edit the background music; of course, the user may also select to upload the background music edited by the user to the tutorial module, and upload the background music and the creation steps together. For example, the background music D is obtained by editing in the steps sa, sb, and sc, and then the background music D, sa, sb, and sc are uploaded to the tutorial module together, so that the user can learn more conveniently.
Preferably, when the user edits the musical instrument music piece, the sounds corresponding to the notes are played synchronously.
In the prior art, when a user edits a musical instrument music piece, the user cannot directly hear the sound corresponding to the musical instrument music piece, but can hear the edited musical instrument music piece only by clicking a play button after the editing is finished, and if one sound goes wrong, the modification is very troublesome. The invention provides a method for instantly playing musical instrument music segments, which can better solve the problems.
Specifically, when a user edits a musical piece of an instrument through one of the instruments, notes input by the user are played synchronously using a playing device. For example, if the user inputs a sound a on the background music editing interface, the sound corresponding to the sound a is played at the time when the user inputs a or at the moment after the input a. Therefore, the user can judge whether the note just input is wrong or not, and if the note is wrong, the note can be timely modified and corrected.
Preferably, the background music editing interface automatically acquires the current time and sends a corresponding instruction to the tutorial module.
Specifically, the background music editing interface acquires the current time, and then judges a vacation corresponding to the current time according to the current time. For example, 12 and 25 correspond to christmas, and then corresponding instructions are sent to the tutorial module, the tutorial module can push a tutorial for editing christmas songs according to the instructions, so that the purpose of reminding holidays of festivals can be achieved, and an editing tutorial which meets the scene can be pushed for a user.
It should be noted that the present invention is specifically applied to the music module of the source code editor. The source code editor is a code editor and comprises a drawing board module, a music module and the like.
