In electronic equipment can be allowed to determine different audio encoding types according to different audio output scenes, and then promoted
Coding control method, device and the electronic equipment for the flexibility that electronic equipment is encoded.
Present embodiments are specifically described below in conjunction with attached drawing.
Referring to Fig. 1, a kind of coding control method provided by the present application, is applied to electronic equipment, which comprises
Step S110: current audio output scene is obtained.
Wherein, as a kind of mode, electronic equipment can determine current according to the application program that front and back is run
Audio output scene.Wherein, application program can be divided into following a few classes according to its operating status:
Foreground application: can usually interact with user, can operate in the application program on foreground, when it is invisible
When will be suspended (such as: game).
Background application: and user's interaction is very limited, during having gone out configuration, the other times of life cycle are all hidden
Hiding (such as: SMS automatically replies program and alarm clock program).
Batch type application program: the application program that can switch between foreground and backstage.
And usually user is during using electronic equipment, if there is application program is in front stage operation, then user's meeting
By the application program of focus to front stage operation.So in order to promote user experience, the current meaning of more intelligent identification user
Whether figure, the application program that electronic equipment can first detect the front stage operation of electronic equipment have audio output, if front stage operation
Application program has audio output, using the corresponding audio output scene of the type of the application program of the front stage operation as current
Audio output scene, it is if the application program of front stage operation does not have audio output, the type of the application program of running background is corresponding
Audio output scene as current audio output scene.
Wherein, as a kind of mode, electronic equipment is android operating system, can pass through execution
The getRunningTasks method of ActivityManager is got currently in the title of the application program of front stage operation.This
Outside, electronic equipment can also obtain the list for the program that user uses by UsageStatsManager, will remember in the list
The most recently used application program of record is identified as current foreground application.Furthermore accessible function can also be carried by android
Can, the variation of window focus is monitored, focus window is taken and corresponds to packet name as the current application program in front stage operation.
Wherein, as a kind of mode, all there is a possibility that playing audio in multiple applications, it is contemplated that how to hand between application
Mutually extremely important, to avoid each music application while playing, the electronic equipment based on Android operation system is burnt using audio
It puts to coordinate the broadcasting of audio, in this case, the application for only getting audio focus can play audio.So electronics
Equipment can detecte get audio focus application program whether be front stage operation application program, to judge front stage operation
Whether application program has audio output.Similarly, it if the application program of detection front stage operation does not have audio output, can also equally adopt
Whether there is the application program of running background to have audio output in manner just described.
Wherein, it should be noted that as a kind of mode, the corresponding audio output scene of application program and application program
Type is related.For example, if the type of application program is game, then corresponding audio output scene is scene of game, if using
The type of program is music, then corresponding audio output scene is music scenario.
Furthermore there may also be different scenes for the same application program.For example, for the application journey of type of play
Sequence may have interface, it is also possible to have music scenario.So in this case, current audio output scene and there is sound
The type at the interface that the application program of frequency output is currently shown is related.If the interface of display is interface, then current sound
Frequency output scene is scene of game, if the interface of display is music-playing interface, then current audio output scene is music
Scene.
It should be noted that game above-mentioned and music are only exemplary citing, the type of application program, using journey
The type and audio output scene at the interface of sequence are not limited to above two.
Step S120: audio encoding type corresponding with the current audio output scene is obtained.
Tables of data storage audio output scene and audio coding class can be stored in advance as a kind of mode, in electronic equipment
The corresponding relationship of type.
In addition, alternatively mode, the available current audio output scene of electronic equipment apply kind
Class, using with it is described using the corresponding audio encoding type of type as the current corresponding audio coding of audio output scene
Type.
Wherein, as a kind of mode, it can still be stored by way of tables of data and be answered belonging to audio output scene
Use type.For example, as shown in the table:
| ID | Back_type | Application_type |
| 1 | Game | 1 |
| 2 | Music | 2 |
Wherein, Field ID indicates the mark of data, and field Back_type indicates audio output scene, Application_
Type indicates to apply type.For example, the corresponding audio output scene of data that ID is 1 is Game (scene of game), and it is corresponded to
Application type be 1, wherein 1 characterization the first kind.The corresponding audio output scene of the data that ID is 2 is (the music field music
Scape), and its corresponding application type is 2, wherein 2 characterization Second Types.Wherein, the corresponding transmission delay of the first type of coding is full
Sufficient pre-set delay condition.The corresponding audio sample rate of second type of coding meets default sampling condition.
It so in this case, will be described if the application type of the current audio output scene is the first kind
Corresponding first type of coding of the first kind is as the current corresponding audio encoding type of audio output scene.If described
The application type of current audio output scene is Second Type, using corresponding second type of coding of the Second Type as institute
State the current corresponding audio encoding type of audio output scene.
Step S130: the audio data based on audio encoding type opposite direction audio-frequence player device transmission is encoded.
A kind of coding control method provided by the present application, before the audio data of exports coding, by obtaining currently
Then audio output scene obtains audio encoding type corresponding with the current audio output scene again, is then based on institute
The audio data for stating the transmission of audio encoding type opposite direction audio-frequence player device is encoded, so that electronic equipment can basis
Different audio output scene determines different audio encoding types, so improve electronic equipment encoded it is flexible
Property.
Referring to Fig. 2, a kind of coding control method provided by the present application, is applied to electronic equipment, which comprises
Step S210: current audio output scene is obtained.
Step S220: the history audio encoding type of the current audio output scene is obtained.
As a kind of mode, if electronic equipment, there is currently audio output, electronic equipment can be in response to acting on electronics
The touch control operation of equipment switches current audio encoding type.
Wherein, touch control operation includes pressing operation and slide.Wherein, pressing operation, which refers to, touches electronic equipment
Display screen after, the operation of certain pressure is persistently generated to the touch position in the display screen.And slide refers to and is touching
Behind a position into display screen, touch points are made to be moved to the operation of another location from the position, and in moving process always
It keeps touching with display screen.
As a kind of mode, in the available preset time period before current time of electronic equipment, with it is described
Frequency is used described in the current identical scene of audio output scene more than setpoint frequency, or it is more than pre- for being used duration
If the audio encoding type of duration is as the history audio encoding type.
As a kind of mode, electronic equipment can be after the current audio output scene of determination, by the determining audio of user
Type of coding storage corresponding with current audio output scene.Wherein, the audio encoding type that user determines can be logical for user
The audio encoding type that manually mode is selected is crossed, or may be that electronic equipment is compiled according to the audio that the rule of setting determines
In the case where not being changed in set period of time after code type, the audio encoding type determined by electronic equipment.
For example, if electronic equipment has triggered music playing process starting, then can on the interface of music playing process
To show multiple alternative audio coding options.For example, as shown in figure 3, showing the name of audio encoding type in control 99
Claim, after detecting user's touch-control control 99, as shown in figure 4, an alternative menu 98 can be shown, in the alternative menu 98
In can show all or part of alternative audio type of coding, so that user can select oneself in the alternative menu 98
Required audio encoding type.
In addition, alternatively mode can also controlled directly other than showing audio encoding type on control
The corresponding effect of audio encoding type is shown on part, not know the corresponding effect of every kind of audio encoding type or advantage
User can the more intuitive audio encoding type selected needed for oneself.For example, as shown in figure 5, in control 99 and alternative dish
It is all that every kind of audio encoding type is shown in a manner of effect in single 98, so that user can more intuitive selection oneself
Required audio encoding type.
It is so based on aforesaid way, electronic equipment, can will be current after getting audio encoding type determined by user
Audio encoding type determined by user carries out corresponding storage with current audio output scene (being music scenario in figure).It can be with
Understand, for stored audio encoding type can by electronic equipment as a history audio encoding type, so as to
After it is music scenario above-mentioned that electronic equipment gets current audio output scene again, music scenario can be directly acquired
Corresponding history audio encoding type is as the corresponding audio encoding type of current music scene.And when defeated for the same audio
When scene has multiple history audio encoding types to be selected out, electronic equipment can be from multiple history audio encoding types to be selected
One type of middle determination is as the history audio encoding type chosen, so that the history audio encoding type chosen is determined as working as
The corresponding audio encoding type of preceding audio output scene.
How the history audio chosen so is determined from multiple history audio encoding types to be selected for electronic equipment
Type of coding will be made below detailed introduction.
Wherein, as a kind of mode, the audio types that scene is played can be exported according to present video to determine.That
, electronic equipment can also correspond to storage and work as in corresponding storage audio output scene and audio encoding type in this case
Preceding audio types.
For example, audio types may include popular song, rock song, supper bass etc. as a kind of mode.If that
Electronic equipment is recorded in this audio output scene of music, for having selected sound under this audio types of popular song
Frequency type of coding is Apt-X coding mode, then electronic equipment can be using Apt-X coding mode as one under music scene
A history audio encoding type to be selected.Similarly, if having selected audio coding under for this audio types of popular song
Type is SBC coding mode, then electronic equipment SBC coding mode can be also used as one under music scene it is to be selected
History audio encoding type.So in this case, electronic equipment detects current institute in the case where entering music scene
The audio types of broadcasting are popular song, then electronic equipment can be from multiple history audio coding classes to be selected of aforementioned determination
In type, when according to history frequency of use length and history using selecting frequency of use maximum in time span and history use
Length is longest as the history audio encoding type chosen.
In addition, alternatively mode, can also determine according to current login user.It is understood that right
In different users, even identical audio output scene, the demand of different users may also can be different, if that root
The history audio encoding type chosen is determined according to the hobby of different users, and electronic equipment can be enabled more flexible
Determine audio encoding type.
So in this case, correspondingly, electronic equipment is in corresponding storage audio output scene and audio encoding type
When, it can also correspond to the user account number for storing and determining the audio encoding type.
Or by taking music scene as an example.If the account number of currently logged on user is account number A under music scene
(account can be the account number of music application program, be also possible to the account number of electronic device system), then for
If the user of account number A has selected Apt-X coding mode, electronic equipment can it is corresponding by account number A, music scene with
And Apt-X coding mode carries out corresponding storage, and then using pt-X coding mode as account number is logged in as account number A in the case where,
A history audio encoding type in music scene, similarly, if still under music scene, if account number
The user of A has selected SBC coding mode, then electronic equipment corresponding can compile account number A, music scene and Apt-X
Code mode carries out corresponding storage, so using pt-X coding mode as account number is logged in as account number A in the case where, in music
A history audio encoding type in scene.So in electronic equipment in the case where entering music scene, detect current
The account number of login is account number A, then electronic equipment can be compiled from the corresponding multiple history audios to be selected of account number of aforementioned determination
In code type, according to history frequency of use length and history, using selecting in time span, frequency of use is maximum or history makes
Use duration longest as the history audio encoding type chosen.
Furthermore in addition to according to other than audio types perhaps user account number can also according to locating for electronic equipment environment or
Other states determine the history audio encoding type chosen.For example, if detecting the current electromagnetic environment of electronic equipment more
Complexity, then in order to guarantee audio frequency effect as far as possible, electronic equipment can choose the good audio encoding type of transmission quality (for example,
Sample rate meets the audio encoding type of preset condition).
In this application, whether electronic can determine electromagnetic environment by detecting the complexity of determining electromagnetic environment
It is complex, and electronic equipment can determine the complexity of current electromagnetic environment in several ways.Optionally, as one
Kind mode, electronic equipment may determine that the quantity for the wlan network for being currently able to search, by the quantity and electromagnetism of wlan network
The complexity of environment is corresponded to.For example, a segment is arrived when the quantity of wlan network is in 0, then corresponding complexity is
1, if the quantity of wlan network is in a to b segment, then corresponding complexity is 2, and so on.In this case,
Higher complexity can correspond to the higher audio coding mode of encoder bit rate.
It is understood that wlan network and bluetooth can work in 2.4GHz frequency range.But it is specifically broadcasted
The channel of signal still have difference.Outside quantity so except through detecting wlan network, electronic equipment can also judge
How many other equipment of channel are also using where the signal of the bluetooth of current broadcast, and then obtain the complexity of electromagnetic environment.
For example, a segment is arrived when the quantity of channel occupancy is in 0, then corresponding complexity is 1, if at the quantity of channel occupancy
In a to b segment, then corresponding complexity is 2, and so on.In this case, higher complexity can correspond to
The higher audio coding mode of encoder bit rate.It is understood that wherein channel occupancy refers to current current electronic device broadcast
Channel used in Bluetooth signal has other electronic equipments also in a situation of use where simultaneously, the quantity of other electronic equipments.
It and in this application, can be in addition to the type above-mentioned by application program is come other than determining audio output scene
Audio output scene is determined by the attribute or classification of audio-frequence player device.For example, currently being connect if electronic equipment detects
The audio-frequence player device for receiving the audio data of its transmission is earphone, then current audio scene can be determined as defeated to earphone
The scene of audio data out.If electronic equipment detects that it is general for currently receiving the audio-frequence player device of the audio data of its transmission
Speaker, then current audio scene can be determined as to general speaker export audio data scene.Furthermore if electric
Sub- equipment detects that the audio-frequence player device for currently receiving the audio data of its transmission is mobile unit, then can will be current
Audio scene is determined as exporting the scene of audio data to mobile unit.
Step S230: using the history audio encoding type as the corresponding audio coding class of current audio output scene
Type.
Step S240: the audio data based on audio encoding type opposite direction audio-frequence player device transmission is encoded.
A kind of coding control method provided by the present application, before the audio data of exports coding, by obtaining currently
Then audio output scene obtains history audio encoding type corresponding with the current audio output scene, then base again
It is encoded in the audio data of history audio encoding type opposite direction audio-frequence player device transmission, so that electronic equipment
Different audio encoding types can be determined according to different audio output scenes, and the audio output scene can be used
The usual history audio encoding type of lower user encodes, so that electronic equipment can preferably match user's habit,
Improve the flexibility that electronic equipment is encoded.
Referring to Fig. 6, a kind of data processing equipment provided by the present application, runs on electronic equipment, described device 300, packet
It includes: scene acquiring unit 310, type of coding acquiring unit 320 and coding unit 330.
