Detailed description of the invention
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.It is understood that this
Specific embodiment described by place is used only for explaining the present invention, rather than limitation of the invention.The most also need
It is noted that for the ease of describing, accompanying drawing illustrate only part related to the present invention and not all knot
Structure.
It also should be noted that, for the ease of describing, accompanying drawing illustrate only portion related to the present invention
Divide rather than full content.It should be mentioned that, some show before being discussed in greater detail exemplary embodiment
Example embodiment is described as process or the method described as flow chart.Although flow chart by operations (or
Step) it is described as process sequentially, but many of which operation can be by concurrently, concomitantly or together
Time implement.Additionally, the order of operations can be rearranged.The most described process can
To be terminated, it is also possible to have the additional step being not included in accompanying drawing.Described process can correspond to
Method, function, code, subroutine, subprogram etc..
Embodiment one
The flow chart of a kind of channel data matching process that Fig. 1 provides for the embodiment of the present invention one, the present embodiment
Being applicable to user by being configured with the situation of the terminal plays stereo music of two speakers, the method can
Performing with the channel data coalignment provided by the embodiment of the present invention, typically, this device can be integrated in
In terminal, such as mobile phone.As it is shown in figure 1, described method specifically includes:
Step 110, according to terminal attitude, determine the first speaker and the second speaker and L channel and R channel
Current matching relation.
Terminal that is concrete, that sell in the market, great majority are equipped with two speakers, with user just
When often using terminal to make a phone call or send short messages premised on the attitude of terminal, the most described first speaker is arranged
At the upper edge of terminal, described second speaker is arranged on the lower edge of terminal；Or described first
Speaker and described second speaker are disposed in parallel in upper edge or the lower edge of terminal, more specifically,
Described first speaker can be arranged on the left side of described second speaker.Such as first speaker is used for playing
Left channel data, the second speaker is used for playing right data, thus realizes the broadcasting of stereo music.
But when be used for playing the first speaker of left channel data from user the more left ear of auris dextra piece closer to time, the
One speaker the most also plays left channel data, from the left ear of user compared with auris dextra piece closer to the second speaker depend on
So also play right data, therefore can cause the stereo music poor effect play, allow some music like
Good person cannot accept.
So in order to realize more preferable stereo music result of broadcast, optionally, can current according to terminal
Attitude, determines the first speaker and the second speaker and L channel and the current matching relation of R channel.Described
I.e. where terminal attitude specifically may refer to two speakers of configuration in terminal and the relative position relation of user,
Individual speaker is close to the left ear of user, and which speaker is close to the auris dextra piece of user.
Step 120, according to described current matching relation, adjust in the present frame of pulse code modulation PCM
Left channel data and the position of right data.
Wherein, described PCM data frame is to exist with certain data form, and described data form can identify
Store in which data bit in PCM data is left channel data, and in which data bit, storage is R channel
Data.When the first speaker and the second speaker and L channel and the current matching relation of R channel and initialization
Time acquiescence matching relationship difference time, then by hardware abstraction layer adjust PCM present frame in L channel number
According to the position with right data.Such as, during initialization, the matching relationship of acquiescence is that left channel data is by first
Speaker is play, and right data is play by the second speaker, when the first speaker and the second speaker are with left
The current matching relation of sound channel and R channel is that the first loudspeaker distance R channel is relatively near, the second loudspeaker distance
When L channel is nearer, then adjusted the left channel data in the present frame of PCM and R channel by hardware abstraction layer
The position of data.
Optionally, above-mentioned steps can be specifically if left channel data and right sound in the present frame of described PCM
When the position of track data is different from described current matching relation, extracted in described present frame by hardware abstraction layer
Left channel data and right data cache, and exchange described left channel data and right data work as
Position in front frame, forms new Frame, and replaces described present frame.
It should be noted that because a lot of third party's algorithms are all at audio frequency ccf layer load operating, such as
Described third party's algorithm can be control particular speaker play the control algolithm of channel data that matches with
And particular channel data are carried out the backoff algorithm of special audio compensation, the voice data after algorithm process
Just can be read by speaker hardware layer and be played out by corresponding speaker.But passing through third party
Before voice data is processed by algorithm, system is not aware that the current matching relation of each speaker and each sound channel,
Therefore, if carry out the exchange of left and right acoustic channels data at speaker hardware layer, can have a strong impact on and raise one's voice with left and right
The third party's algorithm of the device cavity strong correlation compensation effect to voice data, such as certain speaker chamber
Modeling optimization compensates sound effect algorithms.Therefore, it can before loading third algorithm, according to described current matching
Relation, adjusts the left channel data in the present frame of pulse code modulation PCM and right sound by hardware abstraction layer
The position of track data.
Further, according to described current matching relation, adjust the left channel data in the present frame of PCM and
Before the position of right data, described method can also include:
Voice data is processed based at least one algorithm, to obtain described PCM data；
Alternatively, described algorithm can be Doby sound effect algorithms or audio frequency fidelity Dirac algorithm.
When using Doby sound effect algorithms, it is possible to use Doby decoder obtains PCM data；When using Dirac
During algorithm, it is possible to use obtain PCM data after Nuplayer or AwesomePlayer decoding.
Further, on the basis of technique scheme, according to described current matching relation, adjust PCM
Present frame in left channel data and right data position after, described method can also include:
Described PCM data is processed based at least one algorithm following: Doby sound effect algorithms, audio frequency are protected
True Dirac algorithm.To improve the result of broadcast of stereo music or to realize playing except musical sound simultaneously
Other sound in addition.
Step 130, present frame is sent to speaker hardware layer, read present frame for speaker hardware layer
In voice data, and export to described first speaker and the second speaker and play out.
Wherein, present frame is made up of left channel data and right data, can pass through loading third-party algorithm
Controlling left channel data to be play by the first speaker, right data is play by the second speaker, or left sound
Track data is play by the second speaker, and right data is play by the first speaker.
A kind of channel data matching process that the present embodiment provides, by according to terminal attitude, determines that first raises
Sound device and the second speaker and L channel and the current matching relation of R channel, and close according to described current matching
System, adjusts the left channel data in the present frame of pulse code modulation PCM and the position of right data, so
After present frame is sent to speaker hardware layer, read the voice data in present frame for speaker hardware layer,
And export the technological means played out to described first speaker and the second speaker, it is achieved that improve solid
The result of broadcast that sound is happy.
