S101 obtains the playing duration of pending audio data and pending audio data.
In one implementation, it can be when getting new audio file, be obtained according to audio file pending
Audio data.Wherein, when getting new audio file, can be specifically received for the first time from other-end or for the first time from
Network it is locally downloading without audio file at the time of or locally recording obtain new audio file at the time of.
When detecting to have obtained pending audio data, from the attribute information of pending audio data, such as obtained in data head
To the playing duration of pending audio data.Such as the recording file locally recorded after End of Tape, it is obtained from file header
Playing duration to the recording file is 10 minutes.
In another implementation, it can be when receiving the request for playing audio file, be obtained from the audio file
Pending audio data or when receiving the request of audio data for playing and specifying, using specified audio data as treating
Handle audio data.Wherein, when receiving the request for playing audio file, pending audio data is obtained from the audio file
Specific implementation can be：After audio playing request is obtained, audio file to be played is decoded, after obtaining decoding
Pending audio data, pending audio data for example can be decoded coding modulation data (pulse code
Modulation, referred to as：PCM).Obtain the playing duration of pending audio data again after pending audio data is obtained.
S102, according to the playing duration of pending audio data, being obtained from pending audio data has preset tail
The tail portion audio data of portion's playing duration.
Wherein, tail portion playing duration can be specifically according to largely there are the audio data sample of POP sounds, obtain most
The tail portion playing duration of POP sounds may be caused.Tail portion playing duration for example can be 1 second, 2 seconds or 3 seconds.When tail portion plays
It is long, can also be specifically to be determined, such as with pending audio data with the playing duration percentage of pending audio data
The 1% of playing duration is used as tail portion playing duration, such as the pending audio data that playing duration is 300 seconds, tail portion play
Shi Changwei 3 seconds.In an optional implementation manner, it is interior according to the content and this of the pending audio data of playing sequence acquisition
Hold corresponding play time, and whether be tail according to the content that the judgement of the playing duration of pending audio data is currently got
Portion's audio data if the content got is not tail portion audio data, plays out the content got, if obtained
To content be tail data, then carry out the processing step of S103.

Specifically, can be first determining acquisition multiple audio amplitudes maximum amplitude, with maximum amplitude and POP threshold values into
Row multilevel iudge if maximum amplitude is less than or equal to POP threshold values, shows the multiple audio amplitudes obtained both less than or is equal to
POP sound threshold values will not generate POP sounds in the case where POP sound threshold values are sufficiently small, then pending audio data can not be carried out
The processing of POP sounds can further be judged whether there is the possibility for generating POP sounds.If maximum amplitude is more than POP thresholds
Value then shows the audio amplitude for having more than POP sound threshold values in the audio data of tail portion, it is possible to create POP sounds.
After the tail portion audio data that pending audio data is determined is there may be POP sounds, then with preset replacement sound
Frequency is according to the tail portion audio data replaced in pending audio data, the audio data that obtains that treated.Specifically, can be by
The audio-frequency unit for replacing audio data and pending audio data removing tail portion audio data is spliced, the sound that obtains that treated
Frequency evidence.In one implementation, it can be generated according to tail portion audio data to replace audio data, replace audio data
Playing duration it is identical with tail portion audio data, thus obtained treated audio data has and pending audio data phase
Same playing duration.Such as when the playout length of tail portion audio data is 3 seconds, generate one section of replacement audio data of 3 seconds.
In another realization method, replacing audio data can also prestore, and playout length is fixed, with tail portion audio number
According to playing duration may be different, thus obtained treated the playing duration of audio data and broadcasting for pending audio data
Putting duration may be different.Such as the replacement audio data that playing duration is 2 seconds is previously stored with, in tail portion, audio data length is
At 3 seconds, still spliced by the replacement audio data of 2 seconds of playing duration, thus obtained treated audio data
1 second fewer than the playing duration of pending audio data of playing duration.
Wherein, POP sounds threshold value can be determined according to the corresponding amplitude of POP sounds in multiple audio data samples.It replaces
All audio amplitudes of audio data are respectively less than or equal to POP sound threshold values.Specifically, all audio amplitudes of audio data are replaced
Can all be identical audio amplitude or the audio amplitude being gradually reduced.The audio amplitude being gradually reduced has preferable
Fading effect, and with preferable user experience.
