As shown in Figure 1, the process flow of this method may include following step：
Step 101, each note that the note data for obtaining target song includes determines the sound level frequency belonging to each note In rate section, the most sound level frequency separation of occurrence number.
In force, when user wants with simultaneously recording song is sung, it can be opened in terminal and sing application program, sung In the song list for singing application program offer, the song (i.e. target song) for oneself wanting to sing, click is selected to start to record button, then The accompaniment of target song can be played with triggering terminal, and the voice audio data that user sings is detected by microphone, be transmitted to Memory is stored.After recording, terminal can extract note data, note data in the voice audio data of recording Middle mark, sart point in time and the duration for recording the frequency, affiliated sound level frequency separation that have each note.Determine each note Sound level frequency range belonging to frequency chooses the most sound level frequency of occurrence number in these sound level frequency ranges determined Rate range.
Optionally, can be first regular in a series of sound is grouped by all notes, corresponding processing can be as follows：
Step 1, the frequency values for each note for including to note data carry out zooming in or out for 2 integral multiple, respectively It will be in the regular grouping to the preset series of sound of each note.
Wherein, preset series of sound grouping can be arbitrarily arranged according to demand, it is preferred to use the most important frequency band pair of voice The series of sound grouping answered, i.e. the 4th series of sound grouping (series of sound of number 3 is grouped).
In force, by taking the preset series of sound is grouped into the grouping of the 4th series of sound as an example, the 4th series of sound grouping one shares 12 sound levels Frequency separation, each sound level frequency separation have certain frequency range, wherein (the sequence of series of sound grouping of sound level frequency separation 31 Number be 3, sound level frequency separation the series of sound grouping in serial number 1, it is subsequent number with this similarly) lower-frequency limit be The upper frequency limit of 127.088Hz, sound level frequency separation 312 are 254.175Hz.For any note in note data, it is assumed that The frequency values of the note are Note, if Note is more than 254.175Hz, Note=Note/2, until Note is less than or equal to 254.175Hz；If Note is less than 127.088Hz, Note=Note*2, until Note is greater than or equal to 127.088Hz.By After above-mentioned processing, the note is then by the regular grouping to the preset series of sound.Because adjacent series of sound grouping is to differ the pass of octave System multiplies 2 except 2 adjustment will not change serial number of the sound level frequency separation of note in series of sound grouping, so, multiply 2 and is equivalent to By note improve one 8 degree, note is moved to right into a section in table 1, except 2 be equivalent to by note reduction by one 8 degree, in table 1 It is middle that note is moved to left into a section.
During regular processing, after carrying out above-mentioned 2 scaling of integral multiple, the frequency values of note can also be advised The whole centre frequency to the sound level frequency separation being currently located.
Step 2 is determined by the sound level frequency separation belonging to regular treated each note, occurrence number is most Sound level frequency separation.
In force, after carrying out regular processing to note data, some notes are adjusted in note data, some Adjustment (because these notes just belong to preset series of sound grouping originally) does not occur for note.At this point it is possible to determine by regular Sound level frequency range belonging to the frequency of treated each note selects in these sound level frequency ranges determined The most sound level frequency range of occurrence number.
Step 102, it is based on sound level to sort, multiple sound level frequency separations of corresponding basic sound level is set, this multiple sound level frequency Rate section includes the most sound level frequency separation of above-mentioned occurrence number.
Wherein, sound level sequence is that sound level specified in music theory sorts, specially C, C#/Db、D、D#/Eb、E、F、F#/ Gb、G、G#/Ab、A、A#/Bb, B sequence.
In force, multiple sound level frequency separations of corresponding basic sound level can be set, keep above-mentioned occurrence number most Sound level frequency separation is herein among multiple sound level frequency separations, and the corresponding sound level of sound level frequency separation meets sound level sequence.Example Such as, the most sound level frequency separation of occurrence number is sound level frequency separation 33, and sound level frequency separation 31 can be arranged and correspond to C sounds Grade, sound level frequency separation 33 correspond to D sound levels, and sound level frequency separation 35 corresponds to E sound levels, and so on, at this time it can be deduced that sound level Frequency separation 32 corresponds to C#/DbSound level, sound level frequency separation 34 correspond to D#/EbSound level, etc., furthermore it is also possible to deduce, sound level Frequency separation 21, sound level frequency separation 11, sound level frequency separation 41 etc. correspond to C sound levels, because of them and sound level frequency separation The one or more octaves of 31 differences.
Optionally, in addition to determining by the sound level frequency separation belonging to regular treated each note, occurrence number Most sound level frequency separations can also be determined by the sound level frequency separation belonging to regular treated each note, going out Occurrence sound level frequency separation more for several times.In turn, when more if there is the occurrence number of secondary more sound level frequency separation for several times, It can be also configured as to the sound level frequency separation of corresponding basic sound level.Corresponding processing can be as follows：
Situation one, if there is the secondary sound that the occurrence number of more sound level frequency separations includes with above-mentioned note data for several times The ratio for according with number is less than or equal to predetermined threshold value (such as 20%), then is based on sound level and sorts, and the multiple of corresponding basic sound level are arranged Sound level frequency separation, this multiple sound level frequency separation include the most sound level frequency separation of occurrence number.
Specifically, if there is the secondary sound that the occurrence number of more sound level frequency separations includes with above-mentioned note data for several times The ratio for according with number is less than or equal to predetermined threshold value, then the most sound level frequency separation of occurrence number is arranged and corresponds to C sound levels, is based on Sound level sorts, and corresponds to the sound level frequency separation of C sound levels, multiple sound level frequency separations of the corresponding other basic sound levels of setting.
For example, the most sound level frequency separation of occurrence number is sound level frequency separation 35, then sound level frequency can be arranged Section 35 corresponds to C sound levels, sound level frequency separation 37 corresponds to D sound levels, sound level frequency separation 39 corresponds to E sound levels, sound level frequency separation 310 correspond to F sound levels, sound level frequency separation 312 corresponds to G sound levels, 32 corresponding A sound level of sound level frequency separation, sound level frequency separation 34 Corresponding B sound levels, the corresponding sound level of other all sound level frequency separations can deduce according to above-mentioned setting.
Situation two, if there is the secondary sound that the occurrence number of more sound level frequency separations includes with above-mentioned note data for several times The ratio for according with number is more than predetermined threshold value, then is based on sound level and sorts, and multiple sound level frequency separations of corresponding basic sound level are arranged, this Multiple sound level frequency separations include the most sound level frequency separation of occurrence number and the secondary more sound level frequency separation of occurrence number.
Specifically, can be with as shown in Fig. 2, carrying out in accordance with the following steps：
Step S1, if there is the secondary note number that the occurrence number of more sound level frequency separations includes with note data for several times Purpose ratio is more than predetermined threshold value, then the serial number N when the more sound level frequency separation of occurrence number time in the grouping of the preset series of sound The sound level frequency separation most more than occurrence number determines diff=N-M, when N is small in the serial number M during the preset series of sound is grouped When M, diff=N-M+12 is determined.
Wherein, diff is a median for subsequently calculating
Step S2 is handled in the following way according to the difference of diff values：If diff is 1,3,8,10, it is determined that M adds Upper diff is again divided by 12 remainder is serial number P, and setting serial number P corresponding sound level frequency separations in the grouping of the preset series of sound correspond to C sound levels；If diff be 6, it is determined that M plus 7 again divided by 12 remainder be serial number Q, setting serial number Q the preset series of sound grouping in Corresponding sound level frequency separation corresponds to C sound levels；If diff is the numerical value except 1,3,6,8,10, it is most that occurrence number is set Sound level frequency separation corresponds to C sound levels.
Step S3 is sorted based on sound level, and corresponds to the sound level frequency separation of C sound levels, the corresponding other basic sound levels of setting Multiple sound level frequency separations.
The processing of the step is referred to content above.Based on the processing of above-mentioned several steps, then occurrence can be provided The most sound level frequency separation of more sound level frequency separation and occurrence number is all corresponding with basic sound level for several times.
Step 103, in above-mentioned note data, the note of basic sound level is not corresponded to for affiliated sound level frequency separation, it will The frequency values of the note are adjusted in the sound level frequency separation of corresponding basic sound level, obtain revised note data.
In force, by the processing of above-mentioned steps, it may be determined that each corresponding sound level of sound level frequency separation, it can also It is corresponding basic sound level which sound level frequency separation determines, which has, which sound level frequency separation does not correspond to basic sound level.Into one Step, for the note in note data, the sound level frequency separation belonging to note is determined, if the sound level frequency zones belonging to note Between correspond to basic sound level, it may be considered that the note is correct, need not correct, if the sound level frequency separation belonging to note Basic sound level is not corresponded to, then is based on Principles of Acoustics, such note generates discomfort when user can be caused to listen to note data, It is considered that the note is the modified note of needs of mistake, the sound level frequency separation of a corresponding basic sound level can be selected, The frequency values of the note are adjusted in the sound level frequency separation.It may be adjusted to the centre frequency of the sound level frequency separation.
It optionally, can be basic in each correspondence in the sound level frequency separation of one corresponding basic sound level of above-mentioned selection In the sound level frequency separation of sound level, selection and the immediate sound level frequency separation of the note frequencies, because, if belonging to note Sound level frequency separation does not correspond to basic sound level, then, it is certainly corresponding basic with the immediate sound level frequency separation of the note frequencies Sound level.That is, by the frequency values of note, it is adjusted to the sound level frequency zones of closest with the note frequencies and corresponding basic sound level Between in.For example, the frequency of note is 177 hertz, sound level frequency separation 36 does not correspond to basic sound level, then can be by the note Frequency values are adjusted in sound level frequency separation 37, are adjusted to 185 hertz.
Optionally, for above-mentioned the case where carrying out regular processing to note, the processing of step 103 may include such as Fig. 3 institutes The step of showing：
Step T1 does not correspond to basic announcement in by regular treated each note for affiliated sound level frequency separation The frequency values of the note are adjusted in the sound level frequency separation of corresponding basic sound level, the note after being adjusted by the note of grade.
Step T2 carries out the frequency values of the note after each adjustment zooming in or out for 2 integral multiple, respectively will be each Note after adjustment is restored in the grouping of the series of sound where the note before corresponding regular processing, obtains corresponding revised sound Symbol.
