Basic pitch in music is corresponding with the frequency that it is vibrated, and represents the height of note.In a kind of embodiment, to complete
Duan Yinle carries out frequency-domain transform, and then extracts pitch sequence, and not only speed is slow for this mode, and accuracy rate is not also high, it is contemplated that
In computer identification, Short Time Fourier Transform efficiency and accuracy are relatively high, therefore in the present invention, using Fourier in short-term
It converts to extract the spectrogram of music, that is, converts out frequency, and then extract the pitch parameters of music, i.e., obtained in above-mentioned S10
Pitch sequence method particularly includes:
S11: the spectrogram of music is extracted using Short Time Fourier Transform, obtains the frequency sequence of music；
S12: the pitch sequence of music is determined according to frequency sequence.
Wherein, S11 specifically:
First read the data of music；Then, multiple regions are splitted data into, each region progress Fourier transformation are obtained more
A frequency domain；Then, the corresponding frequency of amplitude maximum point in each frequency domain is obtained, field frequency is denoted as, each field frequency forms frequency
Sequence.That is, successively moving Fourier's window in each region carries out multiple Fourier transformation, multiple frequency domains are obtained, are passed through
The frequency values that each frequency domain finds out amplitude maximum point in the frequency domain are scanned, carry out low-pass filtering is equivalent to；Then in amplitude maximum point
Searched whether in corresponding frequency environs with local maximum magnitude point, the environs can as the case may be into
Row setting, as according in " a kind of novel note starting point detection algorithm ", existing musical frequency distribution can be by modern piano
The frequency band of 27.5Hz to 3520Hz is divided into 7 octaves by frequency standard, and each octave is divided into 12 frequency points, then according to calculating
(3520-27.5)/(7*12) ≈ 41.5Hz, the environs can be selected as -20Hz~20Hz, if so, by the local maxima width
Degree point is denoted as region amplitude peak point, if nothing, which is region amplitude peak point, then, most substantially by region
The corresponding frequency of degree point is denoted as field frequency, and each field frequency is arranged successively to form frequency sequence.In this way, Neng Gougeng
Fastly, the pitch parameters of music are more accurately extracted, and then coordinate the variation of the rhythm and light of music more, preferably reminds and uses
Family.
It is formed it should be noted that above-mentioned duration of a sound sequence can be arranged by the duration of a sound in above-mentioned each region, i.e. a region frequency
Rate has a duration of a sound, can also have multiple duration of a sound with a region.
Specifically, the selection in above-mentioned each region can carry out according to the actual situation, if the same area can be continuous and phase
The same duration of a sound.
The rhythm sequences of music are determined in above-mentioned S20 according to pitch sequence and duration of a sound sequence, specifically:
The rhythm sequences of music are determined according to rhythm mapping table according to pitch sequence and duration of a sound sequence, wherein rhythm mapping
Table includes the corresponding relationship of pitch, the duration of a sound and rhythm, wherein and at least one of the corresponding pitch of different rhythm and the duration of a sound are different,
That is, possible pitch is different or the duration of a sound is different, it is also possible to which pitch, the duration of a sound are different in any two rhythm.
There are four kinds of pitch, the duration of a sound, power and tone color different features in music, respectively corresponds the frequency of vibration, continues
The physical quantitys such as time, amplitude and spectrum distribution.Frequency (i.e. the pitch) of vibration this feature is used in the present invention, and is carrying out
The features such as the duration of a sound, power and tone color can cause certain deviation to final field frequency in Short Time Fourier Transform, for example hold
Continuous time (i.e. the duration of a sound) is elongated to impact to the short-term stationarity characteristic of frequency transformation, while its period also has certain change
Change.But in the rhythm mapping table set up in the present invention, by the different duration of a sound, the frequency of the identical pitch of different strong and weak, different tone colors
Rate standard criterion turns to the same frequency, and frequency and duration of a sound combined standard specification are then turned to rhythm, and then forms rhythm and reflect
Firing table improves control efficiency to simplify rhythm mapping table.
Inside music, duration of a sound instantaneous value, different length corresponds to different notes, duration on the basis of whole note successively
Divide half, forms following seven kinds of notes: whole note, minim, crotchet, quaver, semiquaver, 32 partials
Symbol and hemidemisemiquaver.And pitch can be normalized to seven frequencies after obtaining corresponding frequency with Short Time Fourier Transform
Rate respectively corresponds seven pitches do, re, mi, fa, so, la, xi (ignoring herein " tune ", i.e. the pitch position of keynote).Therefore,
In a kind of embodiment of the invention, in rhythm mapping table, the duration of a sound is equipped with seven kinds, is respectively as follows: whole note, minim, quarter step
Symbol, quaver, semiquaver, demisemiquaver and hemidemisemiquaver；Pitch be equipped with seven, be respectively as follows: do, re,
Mi, fa, so, la, xi, do, re, mi, fa, so, la, xi respectively correspond different frequencies, in this way, different groups of pitch, the duration of a sound
Close corresponding available 7*7=49 kind rhythm.For example, when the scale (pitch) of a sound is do, when note (duration of a sound) is whole tone
The first corresponding rhythm；Corresponding second of the rhythm when the scale of another sound is re, and note is eight partial；And work as a sound
Scale is do (ottava alta), when note is also whole tone, since frequency has been normalized inside mapping table, is at this moment corresponded to
Rhythm be also the first rhythm.
In view of only there are five types of (i.e. whole note, minim, crotchet, quaver, ten for note common in music
Six dieresis), and human ear has certain limitation to the length for differentiating a sound to the limited resolution of note, and work as
Continuous two points of the length of one sound when becoming smaller, the difference between adjacent note can also be ignored.In addition to this, in the processing of pitch
On, between seven pitches in tone, the frequency of the latter pitch is that 1.06 times of previous pitch are (average according to 12
Rule), according to human ear to the resolution ratio of pitch, since 32 points are too short with hemidemisemiquaver, ordinary people fails obviously to distinguish；
The present invention is to be mapped as light flash scheme simultaneously, and the note of this short length can be ignored in fact；It can also incite somebody to action
It gets demisemiquaver or hemidemisemiquaver is substituted later with semiquaver, therefore above-mentioned note can letter
It is melted into five pitches.In addition, according to the ancient Chinese five notes of traditional Chinese music: palace-quotient-angle-sign-plumage, i.e. do, re, mi, so, la this five
Sound can take this five notes of traditional Chinese music since the frequency of other fa sound and xi sound is little with the frequency phase-difference of neighbouring sound.It is based on
This, rhythm mapping table of the invention can be further simplified, there are five wherein the duration of a sound is set, be respectively as follows: whole note, minim,
Crotchet, quaver and semiquaver；There are five pitch is set, it is respectively as follows: do, re, mi, so, la, in this way, above-mentioned
49 kinds of rhythm are just reduced to 25 kinds of rhythm.
Light flash sequence is determined according to rhythm sequences in above-mentioned S30, specifically:
Determine light flash sequence according to light mapping table according to rhythm sequences, wherein light mapping table include rhythm with
The corresponding relationship of flashing mode a, wherein rhythm is corresponding at least one flashing mode, i.e., a rhythm can correspond to one kind
Flashing mode, such as above-mentioned 25 kinds of rhythm correspond to 25 kinds of flashing modes, and flashing mode is formed to correspond and be closed in 25 kinds of rhythm and 25
System；It can also be with a rhythm corresponding two kinds, three kinds or more kinds of flashing modes；Or multiple rhythm correspond to a kind of flashing side
Formula.
In addition, in above-mentioned light mapping table, power, color, duration and the change of the light of any two kinds of flashing modes
Change at least one of the frequency (i.e. dwell interval time) difference, i.e., flashing mode can according to the power of light, color, continue when
Between and variation the frequency be arranged to different light flash effects.Certainly, in flashing mode can also other features to light into
Row control.

The assembled arrangement in domain etc. is formed, and is then that different user groups is chosen and its music as adaptable as possible by proposed algorithm.
When formulating user group and selection music, the similar user's set of target user's feature can be found first by filter algorithm,
It is set to a user group, and the music that the user group is liked is recommended into the user group.Specifically, it is necessary first to calculate and use
Family similarity is arranged difference to the weight of different music, takes behavior that can more illustrate user unexpected winner music when calculating
Between similarity, therefore weight can be set higher, be calculated in combination with its individualized feature (such as age).Recommending
When, the music that the highest user of similarity likes listening is recommended into target user.
And in terms of the selection of music, need to consider the length of music.If music is too long, user, which does not allow, easy to identify is
Which music, and can not produce sympathetic response, therefore, it is recommended that music when it is 5 seconds~30 seconds a length of, such as 5 seconds, 6 seconds, 8 seconds, 10 seconds
Deng.
When the control method of above-mentioned light flash is implemented, according to the rhythm of specified music, rhythm mapping table is searched, is rhythm
