Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention is directed to existing middle terminal and realize the problem that KTV ear returns function time delay length, it is provided that multiple solution,
Specific as follows:
Embodiment one
As it is shown in figure 1, the audio data processing method that the embodiment of the present invention one provides, including:
Step 11: utilize the layer adjacent with hardware layer to obtain the voice data of recording from described hardware layer.
When being provided with digital audio processor in the terminal, the layer adjacent with hardware layer refers to comprise digital audio processor
Process layer；When not the most being provided with digital audio processor, the layer adjacent with hardware layer refers to inner nuclear layer.
Step 12: described voice data is carried out audio effect processing, and be mixed in played data and play out.
Sound after step 12 can be specially after voice data carries out audio effect processing and preserve, then acquisition processes at preservation
Frequency is according to playing out.
The audio data processing method that the embodiment of the present invention one provides is mainly used in mobile terminal.
In view of terminal may have digital audio processor, it is likely not to have, so, the embodiment of the present invention is for step 11
Two kinds of specific implementations are provided with step 12:
The first, for having the terminal of digital audio processor, the described utilization layer adjacent with hardware layer from described firmly
The step of the voice data that part layer obtains recording includes: utilization processes layer and obtains the voice data of recording from described hardware layer；
Described audio effect processing that described voice data is carried out, and be mixed into the step played out in played data and include:
Utilization processes layer and described voice data carries out audio effect processing, and is mixed in played data and plays out；Described process layer bag
Include digital audio processor.
The second, for there is no the terminal of digital audio processor, the described utilization layer adjacent with hardware layer from described firmly
The step of the voice data that part layer obtains recording includes: utilize inner nuclear layer to obtain the voice data of recording from described hardware layer；
Described audio effect processing that described voice data is carried out, and be mixed into the step played out in played data and include:
Utilize ccf layer that described voice data carries out audio effect processing, and the voice data after utilizing inner nuclear layer to process is mixed into broadcasting
Data play out.
Utilize ccf layer that described voice data is carried out audio effect processing and can strengthen the stability of system.
In order to prevent from frequently executing audio effect processing operation, in the embodiment of the present invention, described utilize ccf layer to described audio frequency
Data carry out the step of audio effect processing and include: when the frame number of the voice data of recording is more than or equal to preset value, utilize framework
Layer carries out audio effect processing to described voice data.
Could also say that, when the data in recording caching reach preset value, send an event to KTV audio effect processing mould
Block processes.Preset value preferably 240 frame.
In order to ensure to play with recording synchronizes, do not have staccato with sound, in the embodiment of the present invention one, described utilization yet
The layer adjacent with hardware layer includes from the step of the voice data that described hardware layer obtains recording: utilize the layer adjacent with hardware layer
Use the voice data that the first sample rate is recorded from described hardware layer collection；
Described audio effect processing that described voice data is carried out, and be mixed into the step played out in played data and include:

Preferably, the described step that described voice data carries out audio effect processing includes: disappear described voice data
Make an uproar, dynamic compression, equilibrium and reverberation process.Certainly can also include that other operate, and do not limit at this.
Concrete, described described voice data is carried out audio effect processing, and be mixed into the step played out in played data
Suddenly include: described voice data is carried out audio effect processing, and preserves；Voice data after processing is mixed in played data
Row is play.
Preserving the voice data after audio effect processing is to be mixed in played data for the ease of the voice data after processing
Play out.
The audio data processing method provided the embodiment of the present invention one below is further described, with android system
As a example by terminal KTV of system.
In short, return to realize low delay ear, do not increase extra hardware cost, present applicant proposes
Android inner nuclear layer or realize KTV ear in digital audio processor (ADSP) and return the method with audio effect processing:
Mode one
Realize KTV ear with the platform of digital audio processor (ADSP) and return the method with audio effect processing, as shown in Figure 2:
Set up audio frequency and play path (audio playback) with audio sound-recording path (audio record)；At numeral sound
Processor (ADSP) preserves the data of recording (tx) frequently；It is saved in after the data of recording (tx) preserved are carried out audio effect processing
In caching (buffer)；The data mixing of recording (tx) to playing (rx) in digital audio processor (ADSP) played data
In；Mixed data playback out.Record with broadcasting uses same employing rate.
The manner is closer from hardware due to digital audio processor (ADSP), can directly take the data of hardware, warp
The caching (buffer) crossed is little, adds digital audio processor (ADSP) to Digital Signal Processing ratio comparatively fast, processes the time
The shortest, within can accomplishing 30ms, the shortest time delay, people does not feels.
It addition, recording (tx) number after audio effect processing in digital audio processor (ADSP) plays (rx) data
According to being mixed in broadcasting (rx), add that broadcasting is with the identical sample rate of recording, it is ensured that play with recording synchronizes, also will not
Staccato occurs with sound.
A kind of realize low delay KTV ear with digital audio processor (ADSP) platform it can be said that this application provides and return
The method of function, saves hardware cost, provides reasonable Consumer's Experience simultaneously.
Mode two
Without digital audio processor (ADSP) chip, realize KTV ear at android inner nuclear layer and return the side with audio effect processing
Method, as shown in Figure 3:
Set up audio frequency and play (audio playback) with audio sound-recording (audio record) path；In android
Core is protected the data of recording；When the data in recording caching reach 240 frames (5ms), send an event to KTV audio effect processing
Resume module；The data of recording are saved in android kernel after processing through de-noising, dynamic compression, equilibrium, reverberation；?
Android kernel is play the hardware of path and (in android kernel played data, the recording data through audio effect processing is mixed
To playing in path；Mixed data playback out.Record with broadcasting uses same employing rate.
The manner is closer from hardware due to the android kernel of not band digital audio processor (ADSP) platform, can
Directly to take the data of hardware, the caching of process is little, it is possible to reduce the time delay that ear returns；Process is put into Android system
Go in Ceng to process, the stability of system can be strengthened.
It addition, in the data mixing of recording to played data in android kernel plays the hardware of path, add and broadcast
Put with the identical sample rate of recording, it is ensured that play with recording synchronizes, also do not have staccato with sound.
A kind of realize low delay KTV ear without digital audio processor (ADSP) platform it can be said that this application provides and return
The method of function, had both saved hardware cost, also provided reasonable Consumer's Experience.
