The step of frequency of audio signal can be：Terminal obtains the preset field of corresponding audio data of each note moment, according to
The frequency of the audio signal at note moment is calculated in the audio data stored in the preset field.
Wherein, which can need to be arranged and change according to user, and the embodiment of the present invention does not limit this specifically
It is fixed, for example, if the note moment corresponding piece of digital signal is " 01111000101001011000-
00111000011100110010 ", which can be the 21st to the 40th field of the audio data, and therefore, this is default
The audio data stored in field can be " 00111000011100110010 ".
Wherein, predetermined interval can need to be arranged and change according to user, and the embodiment of the present invention is not especially limited this.
For example, the predetermined interval can be 1 second, 10 milliseconds etc..
Step 2022：Terminal is according to the frequency of the audio signal at each note moment, from the correspondence of frequency range and pitch
In relationship, the pitch of the audio signal at each note moment is obtained.
In this step, terminal determines the frequency model where the frequency according to the frequency of the audio signal at each note moment
It encloses, due to the correspondence of frequency range and pitch in terminal storage standard music score, terminal can be according to the frequency institute
Frequency range obtain the corresponding pitch of the frequency from the correspondence of frequency range and pitch, i.e. the frequency is corresponding
The pitch of the audio signal at note moment.
Wherein, the pitch of standard music score can be to indicate that each pitch corresponds to by seven fundamental notes of different scales
Different frequency ranges, the frequency range can need to be arranged and change according to user, and the embodiment of the present invention is not made this specifically
It limits.For example, the corresponding pitch of frequency range of 435 hertz to 445 hertz of the frequency range is 1.
It should be noted that in order to more accurately obtain the destination multimedia file each note moment audio signal
Frequency, terminal can repeat step 202, and when executing 202 every time, and corresponding predetermined interval is different.For example, terminal
When executing step 202 for the first time, to obtain one from the audio signal of the destination multimedia file every 1 second predetermined interval
Note moment corresponding audio signal, terminal next time can be every 0.1 second predetermined intervals from the sound of the destination multimedia file
A note moment corresponding audio signal is obtained in frequency signal.In this way, terminal can be by reducing predetermined interval, and then improve
Obtain the accuracy of the corresponding pitch of multimedia audio file sound intermediate frequency signal.
Step 203：The pitch of the audio signal at each note moment is formed pitch sequence by terminal, according to the pitch sequence
Predetermined interval between row and note moment, determines the sequence of notes of the destination multimedia file.
In this step, terminal can form the pitch of the audio signal at multiple note moment of the destination multimedia file
One pitch sequence, then, terminal determine sound according to the predetermined interval between the adjacent note moment in the destination multimedia file
The corresponding note duration of each pitch in high sequence, and then determine the corresponding note sequence of the destination multimedia file
Row, therefore, this step can be realized by following steps 2031-2032.
Step 2031：Continuous in the pitch sequence and identical multiple pitches are merged into a pitch by terminal, are somebody's turn to do
Each note that the sequence of notes of destination multimedia file includes.
In this step, terminal detection continuously occurs in the pitch sequence and identical multiple pitches, when terminal detects
Continuously occur in the pitch sequence and when identical multiple pitches, multiple pitch is merged into a pitch, since pitch can
With to be indicated by the seven of different scales fundamental note, therefore, it is more to obtain the target according to the pitch sequence after the merging for terminal
The sequence of notes of media file, the sequence of notes include multiple notes.
For example, wherein one section of pitch sequence that the pitch sequence includes can be " 111022200666 ", by the pitch
After 1,2,6 continuously occurred in sequence merge, the corresponding sequence of notes of the pitch sequence can be " 10206 ".
Step 2032：What terminal obtained that each note in the sequence of notes continuously occurs in the pitch sequence goes out occurrence
Number, terminal determine every in the sequence of notes according to the occurrence number and the predetermined interval of each note in the sequence of notes
The lasting duration of a sound of a note.
In this step, the occurrence number which continuously occurs in the pitch sequence should that is, in the pitch sequence
The occurrence number that the corresponding pitch of note continuously occurs, when which is two neighboring note in the destination multimedia file
Time interval between quarter.For each note, terminal is according to the occurrence number and predetermined interval of the note, by the note
The product of occurrence number and the predetermined interval, the duration lasting as the note, the i.e. lasting duration of a sound of the note.
For example, wherein one section of pitch sequence that the pitch sequence includes can be " 1110222006666 ", the pitch sequence
It can be " 10206 " to arrange corresponding sequence of notes, if predetermined interval is 0.3 second, in " 10206 ", and 1,2 lasting sound of note
A length of 0.9 second, the lasting duration of a sound of note 6 was 1.2 seconds.
Step 2033：Terminal by the sequence of notes each note and the duration of a sound form the sequence of notes.
In this step, the duration of a sound is the lasting duration of each note in the sequence of notes, and terminal is according in the sequence of notes
Each note position, each note duration of a sound corresponding with the note is formed into the corresponding note sequence of the destination multimedia file
Row.
Wherein, the lasting duration of each note can be indicated with the type of note in the sequence of notes.For example, if pre-
If the duration of a sound of crotchet is 2 seconds, and the duration of a sound of " 2 " is 2 seconds in sequence of notes, then it is 2 that " 2 " can be expressed as to a duration of a sound
The crotchet of second：2；If the duration of a sound of default quaver is 1 second, and the duration of a sound of " 3 " is 1 second in sequence of notes, then can be with
" 3 " are expressed as the quaver that a duration of a sound is 1 second：3.
Similarly, in order to more accurately obtain the destination multimedia file sequence of notes, terminal can repeat step 202
With 203, and when executing 202 every time, corresponding predetermined interval is different.
Step 204：The sequence of notes is divided into multiple note subsequences by terminal, obtains the section of each note subsequence
It claps.
In this step, sequence of notes is first divided into multiple note subsequences by terminal, according to every in each note subsequence
The pause duration of the duration of a sound of a note and two neighboring note determines the beat of each note subsequence.Therefore, this step can
To be realized by following steps 2041-2043.
Step 2041：Terminal is determined in the sequence of notes and is divided according to the duration of a sound of each note in the sequence of notes
The sequence of notes is divided into multiple note subsequences by the position of beat, terminal according to the position of the division beat.
In the embodiment of the present invention, the duration of a sound that note is preset in sequence of notes is determined as stopping between two neighboring note by terminal
The duration to pause is parked on the position in the sequence of notes according to this, determines the position for dividing beat, therefore, this step can lead to
Following steps 2041a-2041c is crossed to realize.
Step 2041a terminals count each duration of a sound for presetting note according to the duration of a sound of each note in the sequence of notes
With the occurrence number of each duration of a sound.
In this step, which can be the note that pitch is predetermined threshold value, which can be according to user
It needs to be arranged and change, the embodiment of the present invention is not specifically limited this.For example, the predetermined threshold value can be pitch is 0 hertz,
0.1 hertz of pitch.
Step 2041b：Terminal is selected according to the occurrence number of each duration of a sound and each duration of a sound from each duration of a sound
Meet the duration of a sound of preset condition.
In this step, terminal presets the primary pause at note at this using each default note as the sequence of notes, then
The default position of the note in the sequence of notes is the position paused, and the default duration of a sound of the note in the sequence of notes is
The duration of a sound of pause, terminal determine the duration each to pause in the sequence of notes and position, every with this according to each duration of a sound
The occurrence number of a duration of a sound selects the duration of a sound for meeting preset condition from multiple duration of a sound.
Wherein, which can need to be arranged and change according to user, and the embodiment of the present invention does not limit this specifically
It is fixed, for example, the preset condition can be that occurrence number is most；Alternatively, occurrence number is more than the first preset times, or go out occurrence
Number is more than the second preset times and the duration of a sound is more than the default duration of a sound.For example, preset condition, which can be occurrence number, is more than 30 times and sound
It is long to be more than 1 second.
The default duration of a sound, the first preset times and second preset times can need to be arranged and change, this hair according to user
Bright embodiment is not especially limited this.For example, the default duration of a sound can be 1 second, 0.5 second etc., which can be with
It is 80% etc. of total occurrence number of all default notes in 30 times or the sequence of notes, which can be 50
The half etc. of total occurrence number of all default notes in the secondary or sequence of notes.
Step 2041c：Terminal determines the duration of a sound difference between the duration of a sound and the duration of a sound of selection in default model in the sequence of notes
Enclose interior default note, terminal is by the position that location determination of the default note selected in the sequence of notes is division beat.
In the embodiment of the present invention, since the audio signal of the destination multimedia file was waited by a series of compressing and converting
Journey, compressed audio signal can not accurately react the sound of each note in the sequence of notes of the destination multimedia file
Long, therefore, in this step, terminal also needs the duration of a sound to presetting note further to be screened, to accurately determine to draw
The position that merogenesis is clapped.
In this step, terminal is first averaged the multiple duration of a sound for meeting preset condition that terminal in step 2041b selects,
The average duration of a sound of the duration of a sound of multiple selection is obtained, terminal determines the sound between the duration of a sound and the average duration of a sound in the sequence of notes
The default note of long difference within a preset range.
Wherein, which can need to be arranged and change according to user, and the embodiment of the present invention does not do this specific limit
It is fixed.For example, the preset range can be 0.01 second, 0.03 second etc..
Then, terminal obtains the default position of the note in the sequence of notes, is to divide beat by the location determination
Position.
