Optionally, referring to Fig.2, the control method of another kind terminal device disclosed in another embodiment of the present invention, comprising:
S201, audio signal is obtained.
Step S201 is identical as the implementation procedure of the S101 in Fig. 1 and principle, and which is not described herein again.
S202, sub-frame processing is carried out to audio signal, obtains multiple audio frames.
Step S201 is identical as the implementation procedure of the S102 in Fig. 1 and principle, and which is not described herein again.
S203, audio frame to be judged in multiple audio frames is determined；Wherein, audio frame to be judged is in audio signal
Each audio frame.
It should be noted that successively determining each audio frame to be judged, and right according to the playing sequence of audio signal
The audio frame to be judged determined executes step S204 to step S206.
S204, judge whether the average value of audio frame to be judged is less than the average value of the former frame of audio frame to be judged.
Wherein, each audio frame includes N number of sampled point, and the corresponding sampled value of N number of sampled point, which carries out summation, to be obtained
To the sampling and value of the audio frame, the sampling of audio frame and value are subjected to mean value calculation again, being averaged for audio frame can be obtained
Value.Therefore, the average value of audio frame refers to: the average value for the corresponding sampled value of multiple sampled points that audio frame includes.
In this step, the average value of audio frame to be judged can be expressed as AVE (n), the former frame of audio frame to be judged
Average value is expressed as AVE (n-1).After obtaining multiple audio frames that audio signal includes, successively by the audio frame of front cross frame into
Row average value compares, that is, compares AVE (n-1) and AVE (n).If judging AVE (n-1) >=AVE (n), illustrate AVE (0) extremely
Not comprising there is signal specific, the corresponding audio frame of AVE (n) is possible to include specific letter the corresponding audio frame of AVE (n-1)
Number.Therefore, the average value AVE (n-2) of the front cross frame of audio frame to be judged is recorded, the former frame of audio frame to be judged is averaged
The average value AVE (n) of value AVE (n-1) and audio frame to be judged.
It should be noted that the average value of signal specific is other letters that can be greater than in audio signal in audio signal
Number, average value substantially belongs to maximum.That is, several audio frames are averaged before and after signal specific in audio signal
Value is shown with waveform diagram, is wave crest in this audio frame comprising signal specific.But due to being comparing audio frame by frame
The average value of frame can just determine the audio frame only after determining next audio frame of the audio frame after maximum average value
Former frame to be practical include signal specific audio frame, but the audio frame has finished, and therefore, can only select wave crest position
The next audio frame for the audio frame set is as the audio frame including signal specific.
For example, the average value of a certain audio frame to be judged of audio signal is less than sound to be judged in the game of shooting
The average value of the former frame of frequency frame then illustrates that the former frame of audio frame to be judged is the audio frame for actually including shot, wait sentence
Disconnected audio frame is a later frame that sound disappears after shot sounds.It can rapidly disappear after being sounded due to shot, disappearance when shows
Decline for the energy of audio frame, therefore audio frame to be judged is less than the former frame of audio frame to be judged, can illustrate audio to be judged
The former frame of frame is the audio frame for actually including shot.But in audio signal, the interval of two adjacent audio frames is big
About 20 milliseconds, human ear is difficult to tell hear gunshots and hear gunshots after 20 milliseconds or so of sound, usually two sound
As being a sound.Therefore, using the audio frame to be judged as the audio frame that may include shot.
If judging, the average value of audio frame to be judged is less than the average value of the former frame of audio frame to be judged, executes
S205, judge wait judge whether the sampled value of the first sampled point in audio frame is greater than the reference sample value of signal specific.
Wait judge the first sampled point in audio frame for wait judge the maximum sampled point of the sampled value in audio.
Wherein, if judging, the average value AVE (n) of audio frame to be judged is less than being averaged for the former frame of audio frame to be judged
Value AVE (n-1), then explanation should audio frame be judged be possible to include signal specific, it is therefore desirable in conjunction with the in the audio frame
The sampled value of one sampled point further judges whether audio frame to be judged includes signal specific.Specifically, audio frame to be judged
In the sampled value of the first sampled point can be expressed as MAX (n).The reference sample value of signal specific can be expressed as LastMax,
LastMax=MAX (x) * X1, MAX (x) is the maximum sampled value for the last time judging the audio frame comprising signal specific, X1It can be with
Take 80% or other values.If not judging the audio frame comprising signal specific before, the reference sample value of signal specific
LastMax can be zero.
It should also be noted that, it includes therefore signal specific is judging audio frame by frame that audio signal, which may be continual,
During whether frame includes signal specific, it is possible to occur judge at least once include signal specific audio frame.Therefore,
According to the sampled value of the maximum sampled point of sampled value in the last audio frame comprising signal specific judged, spy is calculated
Determine the reference sample value LastMax of signal.
It therefore, will be wait judge the sampled value MAX (n) of the first sampled point in audio frame and the reference sample of signal specific
Value LastMax is compared, and is the maximum sampled value of the audio frame including signal specific judged with the last time, come judge to
Judge whether audio frame includes signal specific.
If judging, the sampled value wait judge the first sampled point in audio frame is greater than the reference sample value of signal specific,
Further illustrate that audio frame to be judged may include signal specific.
If judging, the sampled value wait judge the first sampled point in audio frame is greater than the reference sample value of signal specific,
It executes S206, judge whether the average value of the first audio frame is greater than the reference average value of signal specific；First audio frame include to
Judge the front cross frame of audio frame, the former frame of audio frame to be judged or audio frame to be judged.
The average value of first audio frame can be expressed as the average value AVE (n) of audio frame to be judged, audio frame to be judged
The average value AVE (n-2) of the front cross frame of the average value AVE (n-1) or audio frame to be judged of former frame.The reference of signal specific
Average value can be expressed as LastAVE, LastAVE=[AVE (x-1)+AVE (x)]/2*X2, X285% or other values can be taken.
AVE (x) is the last average value for judging the audio frame comprising signal specific, and AVE (x-1), which then judges for the last time, includes
The average value of the former frame of the audio frame of signal specific.Also, if the audio frame comprising signal specific is not judged before,
The reference average value LastMax of signal specific can be zero.
If judging, the average value of the first audio frame is greater than the reference average value of signal specific, thens follow the steps S207, control
Terminal device processed executes specific operation while playing audio frame to be judged.
Wherein, if judging, the average value of the first audio frame is greater than the reference average value of signal specific, illustrates wait judge
Audio frame includes signal specific, and therefore, controlling terminal device plays audio frame to be judged while executes specific operation.
It should also be noted that, if judging, audio frame to be judged includes signal specific, utilizes audio frame to be judged, more
The new reference sample value LastMax of the signal specific and reference average value LastAVE of signal specific；And it returns to step
S203 determines next audio frame to be judged of multiple audio frames of audio signal, and to the audio frame to be judged determined
Execute step S204 to step S206.
In the present embodiment, in step S204, if judging the average value of audio frame to be judged not less than audio frame to be judged
Former frame average value；Or in step S205, judge that the sampled value wait judge the first sampled point in audio frame is little
In the reference sample value of signal specific；Or in step S206, judge the average value of the first audio frame no more than signal specific
Reference average value, then illustrate that audio frame to be judged then is recorded as invalid sound wait judge not include signal specific in audio frame
Frequency frame, i.e., invalid audio frame count INVALIDNUM adds 1, and returns to step S203.
Threshold value is reset when invalid audio frame count INVALIDNUM is greater than, then resets invalid audio frame count
The reference average value LastAVE of INVALIDNUM, the reference sample value LastMax of signal specific and signal specific.Reset threshold value
It can be set as desired value, it herein can value 5.
It should be noted that step S204, step S205 and step S206, can disclose according to the present embodiment and execute sequence
It successively executes, can also execute, or execute in other orders, not illustrate one by one herein side by side.
