Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0040] Figure 1 FIG. 1 is a flowchart of a music arrangement method according to an embodiment of the present application. Figure 1 As shown, the music arrangement method of the embodiment of the present application includes the following steps:
[0041] S101: Obtain basic music segments;
[0042] Specifically, the basic music segment, that is, the initial music that has not been time-stretched or time-compressed, has its playback duration not processed accordingly, sounds unnatural, and does not reach the user's preset music playback duration.
[0043] S102: generating a fade-out music block by a telescoping logic algorithm according to a preset playing time of the music; and
[0044] Specifically, a fade-out music block refers to a music block in which sound or the like gradually fades out and disappears. The fade-out music block is usually the last music block of a basic music segment, and it ends the music in a gradually weakening manner. According to the preset playing time of the music, the fade-out music block is generated by a telescoping logic algorithm, so that the generated music can sound natural and the playing time can be precisely controlled.
[0045] S103: combining the basic music segment and the fade-out music block to obtain finished music that matches the preset playing time.
[0046] As described above, after the fade-out music block is generated, the fade-out music block is combined with the basic music segment to obtain the finished music that matches the preset playback duration, so as to complete the music arrangement operation.
[0047] Therefore, in the music arrangement method provided in the embodiment of the present application, after obtaining the basic music segment, a fade-out music block is generated according to the preset playing time of the music through a telescopic logic algorithm, and the basic music segment and the fade-out music block are combined to obtain a finished music that matches the preset playing time. Therefore, the music arrangement method provided in the embodiment of the present application can achieve a music effect with a natural listening sense and precise control of the playing time by processing the fade-out music block.
[0048] Further, refer to Figure 2a , Figure 2b and Figure 3 In some embodiments of the present application, the step of obtaining a basic music segment includes:
[0049] The material combination is combined with the basic arrangement to obtain the basic music segment.
[0050] like Figure 2a and Figure 2b As shown, the basic arrangement shown includes 4 music blocks, and the music blocks are used in combination with the audio in the material. The material combination is a collection of music materials (lead, pad, bass, drum) with four tracks. The audio in the collection must have the same music speed (BPM, Beat Per Minute, beats per minute). For example, there are two eight-beat music lengths in the material combination. Therefore, if the music speed of the material is 120BPM, the length of the material is 8 seconds. If the music speed of the material is 90BPM, the length of the material is 10.6666666666667 seconds. If the music speed of the material is 75BPM, the length of the material is 12.8 seconds. If the music speed of the material is 60BPM, the length of the material is 16 seconds. Figure 3 As shown, the basic arrangement shown is composed of four blocks horizontally. If the music speed of the material is 75BPM, then the length of the basic music segment after the material is combined with the basic arrangement is 12.8*4, that is, 51.2 seconds.
[0051] Furthermore, in some embodiments of the present application, the basic music segment includes a plurality of music blocks, and the plurality of music blocks have the same duration.
[0052] As mentioned above, the basic arrangement shown is composed of a total of four music blocks horizontally, and the duration of each music block is the same. For example, if the music speed of the material is 75BPM, then the length of the basic music segment after the basic arrangement is used is 12.8*4, that is, 51.2 seconds.
[0053] Further, in some embodiments of the present application, generating a fade-out music block by a scaling logic algorithm according to a preset playback duration includes:
[0054] Obtaining a multiple of the preset playing time divided by the time length of a single music block of the basic music segment;
[0055] rounding down the multiple to an integer multiple; and
[0056] The actual playing time of the music is subtracted from the product of the integer multiple and the time length of the single music block to obtain the time length of the fade-out music block, so as to generate the fade-out music block.
[0057] Specifically, the music arrangement method provided in the embodiment of the present application can extend or shorten the duration of the fade-out music block through the above steps, so that the total duration of the fade-out music block and other music blocks is equal to the preset playback duration, thereby achieving precise control of the playback duration of the final arrangement.
[0058] Further, in some embodiments of the present application, after subtracting the product of the integer multiple and the duration of the single music block from the actual playback duration to obtain the duration of the fade-out music block to generate the fade-out music block, the method further includes:
[0059] When the obtained duration of the fade-out music block is less than the preset minimum duration, the duration of a single music block of the basic music segment is used as the duration of the fade-out music block, and the actual playing duration of the music is the product of the integer multiple and the duration of the single music block.
[0060] Specifically, if the duration of the fade-out music block obtained according to the steps described above is too short, the listening quality of the final finished music is poor. Therefore, when the duration of the fade-out music block obtained is less than the preset minimum duration, such as 3 seconds, the duration of a single music block of the basic music segment is used as the duration of the fade-out music block, and the actual playback duration of the music is the product of the integer multiple and the duration of the single music block. At this time, there will be a certain time error between the actual playback duration of the music and the preset playback duration, and the range of the time error is between 0 and 3 seconds. The music arrangement method provided in the embodiment of the present application can ensure that the actual playback duration is close to the preset playback duration through the above operation, and at the same time can improve the listening quality of the finished music.
[0061] The music arrangement method provided in the embodiment of the present application, wherein the computer code of the telescoping logic algorithm is as follows:
[0062]
[0063] Figure 4a to Figure 4gThis is an example diagram of the generation process of the final arrangement or finished music involved in the music arrangement method provided in an embodiment of the present application, wherein the fade-out music block is generated by the above code.
[0064] Further, in some embodiments of the present application, after subtracting the product of the integer multiple and the duration of the single music block from the actual playback duration to obtain the duration of the fade-out music block to generate the fade-out music block, the method further includes:
[0065] When the obtained duration of the fade-out music block is less than the preset minimum duration, the last music block of the basic music section is faded out to serve as the fade-out music block.
[0066] That is, if the duration of the fade-out music block is too short, the listening quality of the final finished music will be poor. Therefore, when the duration of the fade-out music block is less than the preset minimum duration, for example, 3 seconds, the last music block of the basic music segment will be faded out as the fade-out music block, thereby ensuring the smoothness of the finished music and improving the listening quality of the finished music.
[0067] Further, in some embodiments of the present application, after obtaining the duration of the fade-out music block by subtracting the product of the integer multiple and the duration of the single music block from the actual playback duration to generate the fade-out music block, the method further includes:
[0068] When the obtained duration of the fade-out music block is greater than the preset minimum duration, the content of the fade-out music block is set to be the same as the content of the last music block of the basic music section.
[0069] As mentioned above, the fade-out music block refers to a music block in which the sound gradually fades out and disappears. The fade-out music block is usually the last music block of the basic music section, which completes the end of the music in a gradually weakening manner. When the duration of the fade-out music block obtained is greater than the preset minimum duration, the content of the fade-out music block is set to be the same as the content of the last music block of the basic music section, thereby further improving the listening experience of the finished music.

[0073] The finished product acquisition module 230 is used to combine the basic music section and the fade-out music block to obtain the finished music that matches the preset playing time.
[0074] In the music arrangement device provided in the embodiment of the present application, after obtaining the basic music segment, a fade-out music block is generated according to the preset playing time of the music through a telescopic logic algorithm, and the basic music segment and the fade-out music block are combined to obtain a finished music that matches the preset playing time.
