It is that melody provided by the embodiments of the present application is dubbed in background music a schematic flow diagram of method referring to Fig. 1.As shown in Figure 1, the rotation Restraining the method for dubbing in background music may include step:

S101 obtains target melody tracks.

In some possible embodiments, the available target melody tracks of terminal.Wherein, in the target melody tracks It may include 16 to 24 melody trifles, may include at least one music beat, each music beat in each melody trifle In may include at least one melody note.For example, the time signature of target melody tracks is 4/4 bat, illustrate that 4 dieresis are a sound Happy beat, each melody trifle have 4 music beats；For another example the time signature of target melody tracks is 2/4 bat, illustrates that 4 dieresis are One music beat, each melody trifle have 2 music beats.On the target melody tracks one the moment only one pitch And duration.The time signature of melody can be using any one of common 4/4 bat, 3/4 bat, 2/4 bat in the target melody tracks, should The tonality of melody can be any tonality, such as the big tune of c major, c ditty, G or a ditty in target melody tracks.The target The duration of music beat is within the scope of preset duration in melody tracks.The preset duration may range from 0.75 second to 1 second Between namely the target melody tracks in melody performance speed between 60bpm to 80bpm.Bpm is music essential term, For indicating how many a music beats per minute.

It should be noted that the time is divided into impartial basic unit in music, each unit is called a Music Day It claps.The duration of music beat is indicated with the duration of note, the duration of a music beat can be crotchet (i.e. with Crotchet is a music beat), it is also possible to minim (with minim for a music beat) or quaver (with quaver for a music beat).The duration of music beat is an opposite concept of time, such as drilling when melody When to play speed be 60bpm (indicate per minute 60 music beats), the time that each music beat occupies is 1 second, half of music Beat is 0.5 second；When playing speed is 120bpm, the time of each music beat is 0.5 second, and half of music beat is exactly 0.25 second, and so on.

In some possible embodiments, the available original melody file including multiple melody notes of terminal, and At least one target melody note can be obtained from multiple melody notes of the original melody file, which can With for indicating the even number melody note in the original melody file, such as the 2nd melody note, the 4th melody note, the 6th Melody note, the 2m melody note are target melody note, and m can be integer, and the value range of m can arrive melody for 1 The half of the quantity of note.It may include initial time and the end time of each melody note in the original melody file.Eventually The initial time of each target melody note at least one target melody note can be shifted to an earlier date each target melody sound by end Corresponding object time threshold value is accorded with, and the end time of the previous melody note of each target melody note can be shifted to an earlier date The object time threshold value, to obtain target melody file.Terminal can obtain target melody sound from the target melody file Rail.The embodiment of the present application is carried out by the duration (initial time of target melody note in advance) to melody in original melody file Adjustment, and enchancement factor (object time threshold value) is introduced in the duration of melody, the unstable sense of music can be increased, to increase Add the unstable sense of melody in target melody tracks.

Wherein, which can be musical instrument digital interface (musical instrument digital Interface, MIDI) format single-tone melody file, which can indicate only one pitch of synchronization With the melody file of duration.The object time threshold value may include 1/2 (start [n]-start [n-1]), 1/3 (start [n]- Start [n-1]) or 1/4 (start [n]-start [n-1]), the start [n] can be used to indicate that n-th of melody note rise Begin time point, which can be used to indicate that the start time point of (n-1)th melody note, n can be to be greater than or wait In 2 even number.

For example, by taking the 2nd in original melody file, the 4th melody note as an example.Terminal will be in original melody file The initial time of 2nd melody note (target melody note) shifts to an earlier date 1/2 (start [n]-start [n-1]), 1/3 (start [n]-start [n-1]) or 1/4 (start [n]-start [n-1]) in any value, such as 1/3 (start [n]-start [n-1]), The end time of the previous melody note (i.e. the 1st melody note) of 2nd melody note is also shifted to an earlier date into 1/3 (start [2] [1]-start), start [2] indicates the initial time of the 2nd melody note, and start [1] indicates the 1st melody note Initial time.The initial time of the 4th melody note (target melody note) in original melody file is shifted to an earlier date 1/2 by terminal Appoint in (start [n]-start [n-1]), 1/3 (start [n]-start [n-1]) or 1/4 (start [n]-start [n-1]) One value, such as 1/2 (start [4]-start [3]), by previous melody note (i.e. the 3rd melody sound of the 4th melody note Symbol) end time also shift to an earlier date 1/2 (start [4]-start [3]), start [4] indicate the 4th melody note starting when Between, start [3] indicates the initial time of the 3rd melody note.

In some possible embodiments, the available original melody file of terminal, and can be from the original melody text The speed parameter (i.e. performance speed) of melody is obtained in part.Whether terminal can detecte the value of the speed parameter in preset speed In range.It, can should if the value of the speed parameter of melody is not in the preset velocity interval in the original melody file The value of speed parameter is adjusted to the target speed value in the velocity interval, obtains target melody file.Terminal can be from the target Target melody tracks are obtained in melody file.Wherein, since the time in music is divided into impartial basic unit, so mesh Mark melody file in music beat when 60 seconds a length of (one minute) divided by the quotient of the target speed value.For example, target is fast Angle value is 70bpm, then the duration of music beat is just 60/70=6/7 seconds in target melody file.Preset velocity interval can be with Between 60bpm and 80bpm.

In some possible embodiments, the available original melody file of terminal, and can be from the original melody text The speed parameter of melody is obtained in part.Terminal can detecte the value of the speed parameter whether in preset velocity interval.If should The value of the speed parameter of melody, then can be by the value of the speed parameter not in the preset velocity interval in original melody file The target speed value being adjusted in the velocity interval.Terminal can be obtained from multiple melody notes of the original melody file to A few target melody note, the target melody note can be used to indicate that the even number melody note in the original melody file, It may include initial time and the end time of each melody note in the original melody file.Terminal can by this at least one The initial time of each target melody note shifts to an earlier date the corresponding object time threshold of each target melody note in target melody note Value, and the end time of the previous melody note of each target melody note can be shifted to an earlier date into the object time threshold value, To obtain target melody file.Terminal can obtain target melody tracks from the target melody file.

S102 determines the first beat duration of dubbing in background music for dubbing in background music track according to the duration of music beat in target melody tracks.

In some possible embodiments, in the available above-mentioned target melody tracks of terminal music beat duration, And the beat duration of dubbing in background music that the duration of music beat in the target melody tracks can be dubbed in background music into track as first, it may be said that bright The speed parameter of the target melody tracks is identical as first speed parameter of track of dubbing in background music.For example, target melody tracks middle pitch Happy beat when it is 6/7 second a length of, then the first beat duration of dubbing in background music for dubbing in background music track is just 6/7 second.Wherein, it first dubs in background music track It can be violoncello track, the violoncello track and the small joint number of above-mentioned target melody tracks, beat number are all the same.

S103, the mapping relations between affiliated range and the first range based on target melody tracks, by target melody sound It is corresponding to obtain each music beat in target melody tracks for the pitch map of the reference melody note of each music beat in rail First pitch generates the corresponding first nervous atmosphere of each music beat according to corresponding first pitch of each music beat and dubs in background music Content, and the beat duration of dubbing in background music for dubbing in background music track based on first dubs in background music each music beat corresponding first nervous atmosphere content The correspondence that track is dubbed in background music in write-in first is dubbed in background music in beat.

In some possible embodiments, in the available target melody tracks of terminal each music beat reference Melody note.This with reference to melody note can in each music beat first melody note or the music beat it is previous First melody note of music beat.If first melody note of some music beat is rest, by the Music Day First melody note of the previous music beat clapped is determined as the reference melody note of the music beat；If the music beat First melody note be not rest, then first melody note of the music beat is determined as to the ginseng of the music beat Examine melody note.The affiliated range and above-mentioned first of the available above-mentioned target melody tracks of terminal is dubbed in background music first belonging to track Mapping relations between range, and can be according to the mapping relations, by the reference of each music beat in the target melody tracks The pitch of melody note is mapped, and corresponding first pitch of each music beat in the target melody tracks is obtained.Terminal can It is dubbed in background music content with generating each music beat corresponding first according to corresponding first pitch of each music beat, this first Content of dubbing in background music may include the pitch near corresponding first pitch of each music beat, e.g., than each music beat pair The pitch of the low sound of the first pitch answered and/or high half of sound.The section of dubbing in background music that terminal can dub in background music track based on above-mentioned first It claps duration and dubs in background music above-mentioned first and determine the corresponding beat of dubbing in background music of each music beat on track, and can be by each music The corresponding first nervous atmosphere of beat content of dubbing in background music is written first correspondence for dubbing in background music track and dubs in background music in beat.Wherein, above-mentioned mesh Marking range belonging to melody tracks can be between small character group G to two groups of g of small character, which can be violoncello track Range belonging to (above-mentioned first dub in background music track), range belonging to the violoncello track can be small character group #C to one group of C of small character Between this octave.

For example, terminal detects corresponding first pitch of each music beat is which sound in C#CD#DEF#FG#GA#AB Height, i.e. CM_pitch [n].CM_pitch [n] indicates corresponding first pitch of n-th of music beat in target melody tracks.It is false If CM_pitch [3] is E, then the corresponding first nervous atmosphere of the 3rd music beat is dubbed in background music, content can be in D, #D, E, F At least two pitch.Assuming that violoncello track dub in background music beat when it is 6/7 second a length of, then the 1st section of dubbing in background music of expression in 0 to 6/7 second It claps, the 2nd beat of dubbing in background music of expression in 6/7 second to 12/7 second, and so on.Terminal is existed based on the beat duration of dubbing in background music of violoncello track Corresponding 3rd beat of dubbing in background music of the 3rd music beat is determined on violoncello track, i.e., between 12/7 second to 18/7 second.Terminal will The corresponding first nervous atmosphere of 3rd music beat is dubbed in background music the 3rd section of dubbing in background music of content (such as #D and E) write-in violoncello track It claps, i.e., between 12/7 second to 18/7 second of write-in violoncello track.

S104, merges target melody tracks and the nervous atmosphere of write-in first is dubbed in background music after content first dubs in background music track, obtains Target melody tracks are matched music file and are exported.

In some possible embodiments, terminal can be according to the correlation in evolution of time, by above-mentioned target melody tracks It is merged with the above-mentioned first nervous atmosphere the first track (violoncello track) of dubbing in background music after content of dubbing in background music is written, obtains text of dubbing in background music Part, and this is exported with music file with midi format.This is with the theme that music file may include in the target melody tracks.Example Such as, in t moment, target melody tracks and violoncello track are simultaneously emitted by the sound of each comfortable t moment.The embodiment of the present application passes through The content of dubbing in background music of nervous atmosphere is written in violoncello track, to generate the sense of hearing accelerated, then violoncello track and target is revolved Note rail merges output, can increase the tension of music, thus realize that the melody not limited by the person's of dubbing in background music level is dubbed in background music, Obtain building nervous atmosphere with music file, while making music more harmonious true.
