Embodiment
First embodiment
Fig. 1 is referred to, Fig. 1 shows a kind of flow chart for light generation method that the application first embodiment provides, bag
Include following steps：
Step S110, is handled voice data, obtains audio analysis result data.
Fig. 2 is referred to, step S110 specifically comprises the following steps：
Step S111, cutting is carried out to voice data, obtains multigroup voice data.
Cutting is carried out to voice data, to obtain multigroup voice data, specifically, can be stopped according between voice data
Immediately come to carry out cutting to voice data between, cutting can also be carried out to voice data according to prefixed time interval.
Step S112, Fast Fourier Transform (FFT) is carried out to every group of voice data in multigroup voice data, obtains spectrum number
According to.
Fast Fourier Transform (FFT) is carried out respectively to the multigroup voice data cut out, so as to obtain frequency spectrum data.
Step S113, carry out peakvalue's checking, the detection of rhythm point, loudness detection, energy spectrometer respectively to the frequency spectrum data
And tone color analysis, obtain audio analysis result data.
Peakvalue's checking, the detection of rhythm point, loudness detection, energy spectrometer and tone color minute can be carried out respectively to frequency spectrum data
Analysis.For example, carrying out loudness detection to frequency spectrum data, the dispersion of frequency spectrum data can be specifically detected, if dispersion is big, is illustrated
Loudness is higher；For tone color, then the tone color of itself and database purchase can be contrasted.
Step S120, according to the audio analysis result data and lighting effects material, obtain lighting effects driving life
Order, wherein, the lighting effects drive command includes multiple time points of the voice data, and every in multiple time points
Individual time point light light on and off data.
Wherein, step S120 can be specifically included：Obtain the dispersion of loudness numerical value in audio analysis result data.If the
The dispersion of loudness numerical value corresponding to one time point is more than default number of discreteness, then by voice data corresponding to the first time point
Labeled as climax.The first signal light control data corresponding with climax are searched from the lighting effects material database.Establish this first
Time point and the mapping relations of the first signal light control data.
Feature according to corresponding to audio analysis result acquisition voice data at each time point, such as loudness height are then designated as
Climax, signal light control data corresponding with climax are then searched from lighting effects material database again, such as A lamp is with high-high brightness
Chang Liang, you can using as signal light control data corresponding with climax, then using the signal light control data as the first signal light control number
Mapping relations are established according to the first time point occurred with climax.

Step S130, obtain the spectral energy values in audio analysis result data.
The spectral energy values in audio analysis result data are obtained, the spectral energy values can the frequency spectrum through frequency spectrum data point
Analysis obtains.
Step S140, obtain the spectrum energy section where the spectral energy values at the second time point.
After obtaining specific spectral energy values, judge the spectral energy values are located at which area in multiple spectrum energy sections
Between, for example, can specifically include 3 spectrum energy sections, the first spectrum energy section is a~b, and the second spectrum energy section is
B~c, the 3rd spectrum energy section are c~d.Acquisition spectral energy values are b1, and b1 is more than b and is less than c, then b1 and the second frequency spectrum
Energy section is corresponding.
Step S150, the emotional expression area corresponding to the spectrum energy section is obtained, and the emotional expression area corresponds to
The second signal light control data.
Each spectrum energy section corresponds to different emotional expression areas respectively, such as three spectrum energy sections can be distinguished
Corresponding cheerful and light-hearted, dull, tranquil three kinds of emotional expressions.And every kind of emotional expression has corresponded to different light.
Specifically, the emotional expression area is corresponding with multiple emotion expression service material ponds, the step specifically includes：Described in acquisition
Emotional expression area corresponding to spectrum energy section；It is random from multiple emotion expression service material ponds corresponding to the emotional expression area
An emotion expression service material pond is chosen, the signal light control data in the emotion expression service material pond are obtained, as the second light
Control data.
Every kind of emotion can be presented and expressed by different light, therefore, even same emotional expression area, also right
There should be multiple emotion expression service material ponds, different signal light control data are corresponding with each material pond, can be at random from multiple feelings
Thread expression material selects one kind in pond, and using its corresponding signal light control data as the second signal light control data.Second light
The light fixture of control data control can be different from the light fixture that the first signal light control data control, i.e. the first signal light control data and the
Two signal light control data can cooperate.
The element of the material effect superposition of every kind of affective characteristics is position, color, the quantity of time light fixture, can be basis
The database of the experience accumulation generation of light controller, these materials can be widely applied to various positions, color, light fixture, fold
These elements have been added just to turn into specific effect programs fragment or scene afterwards.
Step S160, establish the mapping relations at second time point and the second signal light control data.
Second signal light control data and the second time point are established into mapping relations, specifically, when the second time point is with first
Between point can be same time point.
First signal light control data and the second signal light control data can a series of be directed to lighting effects material unit
Presentation mode and combination, such as the control command of the 30th second is：1 signal lamp turns yellow, 2 signal lamp greenings, and 3 signal lamps are gradual in 5 seconds
It is changed into purplish red from pink, 6 signal lamps and 7 signal lamps start stroboscopic, and 8 signal lamps turn to 135 degree.The control command of the 40th second
It is changed into white light for all light fixtures, and irradiates the angle of some fixation.
The light generation method that the application first embodiment provides can be handled voice data in real time, obtain audio
Analysis result data, lighting effects driving life is then obtained by audio analysis result data and lighting effects material data again
Order.With existing tuner directly carry out light programming compared with, the application provide light generation method workload it is small, cost compared with
It is low.
