Description
Technical field
The invention belongs to mobile terminal MultiMedia Fields, more particularly to by the dynamic data of device plays volume of music come real
When draw audio animation display effect.
Background technique
With the rapid development of scientific information technology, multimedia technology has also been deep into huge numbers of families, people's lives
Huge change has occurred, has also pushed the development of society.Incident mobile terminal is also almost that manpower has to the greatest extent, and movement is set
Standby increase has brought people's great convenience, and people is also allowed to become increasingly conspicuous the demand of mobile terminal multimedia technology.At present
Various softwares emerge one after another in the market, and many softwares all have the function of audio broadcasting, and people are very easily using
While these functions, it has been not only to only require to hear sound that the effect requirements played to audio are also higher and higher,
It prefers to it can be seen that the dynamic variation tendency of entire audio.For by traditional music, result of broadcast cannot
Meet the user experience of people, so the audio based on mobile terminal now is played there is also the status that it is still necessary to improve,
Invent a volume change data for present terminal system and what the Dynamically Announce effect that plays to audio was handled
A kind of method, the more intuitive variation effect for reflecting entire audio in playing process in animated way, more intuitively
The dynamic melody for showing current music, brings the better visual effect of user, promotes the visual experience of user.
Summary of the invention
The purpose of the present invention is, there is also the status that it is still necessary to improve, provide one for existing audio result of broadcast
The processing method of the animation effect of the more intuitive reflection current volume amplitude variation of kind.Central principle is that current system is playing
When audio, corresponding current fluctuation can be generated, the data that the system sound volume by monitoring and obtaining present terminal changes, foundation is thought
The audio Dynamically Announce effect to be realized, writes the algorithm of a series of complex to draw out actual audio animation, reaching can
The control of animation is carried out according to the actual conditions that audio plays, while providing a dynamic again and receiving the variation of current system audio
The interface of data, to draw corresponding audio animation in real time.
The specific steps of the method for the present invention are as follows:
Step 1: android audio frame is called to provide the derived class Visualizer of base class AudioEffect, monitor
And obtain the volume change data in current system data.
Data source can generate corresponding current fluctuation when system is playing audio in system, and system bottom will be electric
Stream fluctuation is converted into byte (byte) data.
Firstly, it is necessary to register corresponding permission: " android.permission.MODIFY_AUDIO_ in android
SETTINGS ",
Secondly, obtaining Visualizer example in the activity for needing to show audio animation；
Then, corresponding sampled value setCaptureSize, monitor setDataCaptureListener are set, set
When setting monitor, need to select the interface of return parameters, the waveform sampling returned using onWaveFormDataCapture
Byte arrays；
Finally, starting to sample setEnabled (true).
Step 2: drawing animation by corresponding algorithm, and provide reception according to the audio display effect of desired realization
The interface of dynamic changing data.
Step 2 needs to be accomplished that a dynamic grid spectrogram, it is therefore desirable to the VIEW of a customized animation,
The relevant parameter of paintbrush Paint and painting canvas canvas are determined first, the parameter of paintbrush Paint includes: thickness, color and style,
Wherein brush color is made of 8 kinds of colors, and color sorts from top to bottom from shallow to deep；Thickness and style are specified one
Kind；Painting canvas canvas relevant parameter includes long and wide.
Specific according to incoming volume change data dynamic select gradation of color: the longitudinal axis is for showing square
Quantity, top-down color successively arrange from shallow to deep；
According to square columns fixed in the length of incoming volume change data, X direction, incoming volume change
The content of data, calculates the square quantity on each column longitudinal axis, then using the fixed blocks quantity in the X direction of setting as
Recurring number, circulation draw the square quantity on the longitudinal axis.
The square quantity calculating specifically calculated on each column longitudinal axis is accomplished by
Audio result of broadcast is indicated according to audio waveform data using the rectangle of color gradient, if the wave sequence obtained is
S{w1,w2,……wp, wherein p indicates the number of data in sequence S, if the maximum value of element is Max in sequence S, Max is big
In 0 natural number；Minimum value is-Max, if indicating that the rectangle of audio result of broadcast figure this moment is matrix Amn, wherein m and n are
Natural number, m indicate that the maximum number of lines of setting, n indicate the maximum number of column of setting, rectangle aijFor matrix AmnElement, wherein i, j
It is natural number, 0≤i < m, 0≤j < n, if the graduated colors sequence used is C { c0,c1,……,cq}
If rectangle aijThe rectangle number of column is Countj, then CountjFollowing calculation can be used to obtain
Work as wxWhen > 0, Countj=┌ m/2+ (Max-wx) * m/Max ┐ wherein x=┌ p/n*j ┐；
Work as wxWhen≤0, Countj=┌ m/2+ (- Max-wx) * m/Max ┐ wherein x=┌ p/n*j ┐；
So rectangle aijColor Vcolour obtained using following calculation
Work as m-i > Countj, Vcolour=0
As 0≤Countj- m+i < q, Vcolour=CCount-m+i
Work as Countj- m+i >=q, Vcolour=Cq
Wherein 0 expression color is consistent with background colour can not have to draw, using above-mentioned when changing wave sequence S
Calculation calculating matrix AmnThe color of each rectangle, right in the rectangle number and each column rectangular set that middle each column should actually be drawn
Rectangle AmnAgain it draws, can dynamically show audio result of broadcast figure.
Step 3: the volume change data got in step 1 to be passed to the interface provided in step 2, draw in real time
Audio animation effect processed.
Step 3 needs to show the XML file of frequency spectrum animation, quotes customized animation VIEW in step 2, in XML text
Monitoring in Activty belonging to part in setting steps one, and be passed to the volume change data got are monitored in step 1
The interface provided in step 2；Then music is played, the generation of continuous volume change data is had and incoming step 2 provides
Interface, the display effect of the dynamic data real-time rendering audio animation by volume can be realized.
The present invention has the beneficial effect that:
The main object of the present invention is to show the fluctuation of current device music VF being played in animated way, is given
User more intuitively shows the dynamic melody of current music, brings better visual effect, user experience to user.
This have the advantage that: by the Wave data of sampling system currently playing music, carry out real-time rendering animation,
The dynamic melody of current music is shown by different color blocks, to user with visual grand banquet, passes through the square of bounce
The innervation and pleasant sensation of user's music are brought, user experience is promoted.
Specific embodiment
The present invention is illustrated below with reference to embodiment.
When central principle of the present invention is that current system is playing audio, corresponding current fluctuation can be generated, passes through monitoring
And the data for obtaining the system sound volume variation of present terminal are write a series of according to the audio Dynamically Announce effect for wanting to realize
Complicated algorithm draws out actual audio animation, and the actual conditions that reaching can play according to audio carry out the control of animation
System, while the interface that a dynamic receives current system audio delta data is provided again, to draw corresponding audio in real time
Animation.
The specific steps of the method for the present invention are as follows:
Step 1: android audio frame is called to provide the derived class Visualizer of base class AudioEffect, monitor
And obtain the volume change data in current system data.
Data source can generate corresponding current fluctuation when system is playing audio in system, and system bottom will be electric
