A kind of more audio services of highly efficient, function, preferably improve the experience of user.
After the detailed description of embodiment of the present invention is read in conjunction with the figure, other features of the invention and advantage will become more
Plus it is clear.
Brief description of the drawings
Fig. 1 is the flow chart of the embodiment according to the inventive method.
Fig. 2 is the structural representation of the embodiment according to present system.
For clarity, these accompanying drawings are figure that is schematic and simplifying, and they are only gived for understanding institute of the present invention
Necessary details, and omit other details.
Specific embodiment
Embodiments of the present invention and embodiment are described in detail with reference to the accompanying drawings.
By detailed description given below, the scope of application of the invention will be evident that.It will be appreciated, however, that detailed
While thin description and specific example show the preferred embodiment of the present invention, they are given only for illustration purpose.
At present, the audio framework of Android phone is：AudioFlinger audio services call downwards Audio Hal layers
(full name of HAL is Hardware Abstraction Layer, i.e. hardware abstraction layer), Audio Hal can be instructed with AT is sent
The mode and modem Modem of (AT is Modem commands language) are communicated, while Audio Hal layers can be downward
TinyAlsa (function library of Google audio) is called, ASOC frameworks (ALSA System on Chip are called downwards afterwards
(ALSA (Advanced Linux Sound Architecture) refers to senior Linux sound framework)), finally it is transferred to Audio
Driver layers (audio driven).
Audio framework on personal computer is：Pulseaudio audio services call downwards alsa storehouses, afterwards to downward
ASOC frameworks are used, Audio Driver are finally transferred to.
The present invention proposes to be supported using a kind of audio hardware platforms based on ALSA frameworks, using PulseAudio as
The solution of audio service.
With reference to flow chart shown in Fig. 1 to it is of the invention offer audio service method an embodiment each step
Suddenly it is specifically described.
In step S102, will be handed over modem in the audio hardware level of abstraction Audio Hal of mobile terminal such as mobile phone
Mutual logical gate is separated and obtains transplanting Audio Hal.Three parts are mainly included in Audio Hal layers of Android：
Voice data hop, voice-frequency channel control section, voice voice calls part, wherein voice voice calls part is
The logical gate interacted with modem.According to a kind of implementation method, transplanting Audio Hal are obtained by following treatment：Cut out
Fall the voice data hop in mobile terminal Audio Hal and voice-frequency channel control section, retain voice voice calls portion
Point；Alsalib storehouses are called by calling the interface function in TinyAlsa storehouses to be all substituted in the voice voice calls part of reservation
Interface function；The voice voice calls part treated by back is recompilated with glibc function libraries, is transplanted
Audio Hal。
In step S104, the transplanting Audio Hal are packaged into an Audio Hal plug-in unit.
In step S106, the Audio Hal plug-in units are integrated into PulseAudio audio services and obtain new
PulseAudio audio services so that the new PulseAudio audio services can automatically call the Audio upon actuation
Hal plug-in units.
In step S108, the new PulseAudio audio services are used as the audio service of the mobile terminal, replaced
For previous AudioFlinger audio services.
According to a kind of implementation method of the inventive method, methods described also includes：The new PulseAudio audios clothes
The ALSA storehouses of standard are called downwards in business, afterwards, ASOC layers are further called downwards, and further call audio driven downwards afterwards
Device Audio Driver.
The present invention neutralizes the logical gate transplanting that Modem is interacted by Audio Hal layers that cell phone apparatus manufacturer is provided
Operation out is gone as a plug-in unit of PulseAudio, Audio Hal can downwards call the ALSA storehouses of standard afterwards, and no longer
Call TinyAlsa storehouses.Meanwhile, Audio Hal layers still can interact communication using AT instructions and modem, complete phone phase
The treatment in logic closed.Pass downwardly through afterwards and call ASOC layers, Audio Driver are called still further below.So that
PulseAudio can be used in cell phone apparatus so that the audio service of cell phone apparatus has the advantages that PulseAudio.
