Step 12: audio effect processing being carried out to the audio data, and is mixed into played data and plays out.
Step 12 can be specially to save after carrying out audio effect processing to audio data, then obtain treated sound from preservation place
Frequency evidence plays out.
The audio data processing method that the embodiment of the present invention one provides is mainly used in mobile terminal.
In view of that there may be digital audio processor in terminal, may not have, so, the embodiment of the present invention is directed to step 11
Two kinds of specific implementations are provided with step 12:
The first, for the terminal with digital audio processor, it is described using the layer adjacent with hardware layer from described hard
The step of audio data of part layer acquisition recording includes: the audio data for obtaining recording from the hardware layer using process layer；
It is described that audio effect processing is carried out to the audio data, and be mixed into the step of playing out in played data and include:
Audio effect processing is carried out to the audio data using process layer, and is mixed into played data and plays out；The process layer packet
Include digital audio processor.
Second, for the terminal of not digital audio processor, it is described using the layer adjacent with hardware layer from described hard
The step of audio data of part layer acquisition recording includes: the audio data for obtaining recording from the hardware layer using inner nuclear layer；
It is described that audio effect processing is carried out to the audio data, and be mixed into the step of playing out in played data and include:
Audio effect processing is carried out to the audio data using ccf layer, and audio data is mixed into broadcasting by treated using inner nuclear layer
It is played out in data.
Carrying out audio effect processing to the audio data using ccf layer can be enhanced the stability of system.
Audio effect processing is frequently executed in order to prevent to operate, it is described to utilize ccf layer to the audio in the embodiment of the present invention
The step of data progress audio effect processing includes: to utilize frame when the frame number of the audio data of recording is greater than or equal to preset value
Layer carries out audio effect processing to the audio data.
It could also say that, when the data in recording caching reach preset value, send an event and give KTV audio effect processing mould
Block processing.Preset value preferably 240 frames.
It is synchronized to guarantee to play with recording, staccato will not occur with sound, in the embodiment of the present invention one, the utilization
The step of layer adjacent with hardware layer obtains the audio data recorded from the hardware layer includes: to utilize the layer adjacent with hardware layer
The audio data recorded using the first sample rate from hardware layer acquisition；
It is described that audio effect processing is carried out to the audio data, and be mixed into the step of playing out in played data and include:
Audio effect processing is carried out to the audio data, and is mixed into played data and is played out using first sample rate.
Preferably, described the step of carrying out audio effect processing to the audio data includes: to disappear to the audio data
It makes an uproar, dynamic compression, equilibrium and reverberation processing.It certainly can also include other operations, it is not limited here.
Specifically, described carry out audio effect processing to the audio data, and it is mixed into the step played out in played data
It suddenly include: audio effect processing to be carried out to the audio data, and save；Will treated audio data is mixed into played data into
Row plays.
Audio data after saving audio effect processing is for the ease of by treated, audio data is mixed into played data
It plays out.
The audio data processing method provided below the embodiment of the present invention one is further described, with android system
For the terminal KTV of system.
In short, in order to realize that low delay ear returns, do not increase additional hardware cost, present applicant proposes
Android inner nuclear layer realizes that KTV ear returns the method with audio effect processing in digital audio processor (ADSP):
Mode one
Platform with digital audio processor (ADSP) realizes that KTV ear returns the method with audio effect processing, as shown in Figure 2:
It establishes audio and plays access (audio playback) with audio sound-recording access (audio record)；In digital sound
The data of recording (tx) are saved in frequency processor (ADSP)；It is stored in after carrying out audio effect processing to the data of the recording (tx) of preservation
It caches in (buffer)；The data mixing of recording (tx) to broadcasting (rx) in digital audio processor (ADSP) played data
In；Mixed data playback is come out.Recording is with playing using similarly using rate.
The method can directly take the data of hardware since digital audio processor (ADSP) is closer from hardware, warp
The caching (buffer) crossed seldom, along with digital audio processor (ADSP) is very fast to Digital Signal Processing ratio, handles the time
It is especially short, it can accomplish within 30ms, delay short in this way, people, which does not feel, to come.
In addition, playing the number in (rx) data recording (tx) after audio effect processing at digital audio processor (ADSP)
It is played in (rx) according to being mixed into, in addition playing with identical sample rate of recording, it is ensured that it plays and is synchronized with recording, it will not
There is staccato with sound.
Realize that low delay KTV ear returns with digital audio processor (ADSP) platform it can be said that this application provides one kind
The method of function saves hardware cost, while providing relatively good user experience.
Mode two
Without digital audio processor (ADSP) chip, realize that KTV ear returns the side with audio effect processing in android inner nuclear layer
Method, as shown in Figure 3:
It establishes audio and plays (audio playback) with audio sound-recording (audio record) access；In android
The data of recording are protected in core；When the data in recording caching reach 240 frames (5ms), sends an event and give KTV audio effect processing
Resume module；The data of recording are passed through de-noising, dynamic compression is balanced, is saved in android kernel after reverberation processing；?
Android kernel plays the hardware of access (the recording data mixing by audio effect processing in android kernel played data
Into broadcasting access；Mixed data playback is come out.Recording is with playing using similarly using rate.
The method is closer from hardware due to not having the android kernel with digital audio processor (ADSP) platform, can
Directly to take the data of hardware, the caching of process is seldom, it is possible to reduce the delay that ear returns；Processing is put into Android system
It goes to handle in layer, the stability of system can be enhanced.
In addition, in the hardware that android kernel plays access the data mixing of recording into played data, in addition broadcasting
It puts with identical sample rate of recording, it is ensured that play and synchronized with recording, staccato will not occur with sound.
Realize that low delay KTV ear returns without digital audio processor (ADSP) platform it can be said that this application provides one kind
The method of function, both saves hardware cost, also provides relatively good user experience.
The audio data processing method that the embodiment of the present invention one provides may be used also other than it can be applied to mobile terminal KTV
To be applied to the sound that other need to record, the scene played back in real time.
