The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used to explain the present invention, rather than limitation of the invention.It also should be noted that for the ease of retouching
State, part related to the present invention rather than entire infrastructure are illustrate only in accompanying drawing.
Fig. 1 is a kind of flow chart of volume adjusting method provided in an embodiment of the present invention, and the present embodiment was applicable to end
End equipment carried out during source of sound broadcasting the situation of volume adjusting, and this method can be by terminal device provided in an embodiment of the present invention
To perform, the volume adjustment device of the terminal device can be realized by the way of software and/or hardware, as shown in figure 1, this implementation
The concrete scheme that example provides is as follows：
Step S101, when detecting that terminal device carries out source of sound broadcasting, the audio of the preset length of the source of sound is obtained
Information.
Terminal device can carry out source of sound by the audio and video playing software that the third party application or system of installation carry
Broadcasting.Wherein, the steps such as acquisition, decoding and output of audio files are mainly included.Exemplary, the audio files got
It can be the multicast data flow received by network, can also be the audio-video document that terminal device is locally stored；Get the sound
It is loaded into after source file in core buffer；The audio files for being loaded into core buffer are decoded, opened in decoding
Before beginning, if the audio files include video data, it is necessary to carry out the separation of voice data and video data simultaneously, it will divide
Voice data from after is inputted to audio decoder, wherein, audio decoder is mainly used in reading the audio in core buffer
Data, digital audio and video signals are obtained, and the digital audio and video signals are converted into simulated audio signal, the broadcasting device of terminal device
Audio broadcasting is carried out according to the simulated audio signal.In one embodiment, when listening to source of sound broadcast event and being triggered, really
Determine terminal device and commence play out source of sound, wherein, the trigger event can be the broadcast button quilt shown in the touch-screen detected
Press, can also be when detecting the broadcasting device of terminal device for example loudspeaker commencing play out sound, determine that terminal device carries out sound
Source plays.
When detecting that terminal device carries out source of sound broadcasting, the audio-frequency information of the preset length of the source of sound is obtained.One
In individual embodiment, the digital audio and video signals that can decode to obtain to audio decoder are sampled, and determine audio corresponding to the source of sound
Information, wherein preset length can be 3s, 5s or 10s etc..In another embodiment, currently playing source of sound can also be obtained
Original document, the audio-frequency information of preset length corresponding to source of sound is determined by the parsing to the original document.In another embodiment
In, by taking android system as an example, can by android.media.MediaRecorder classes or
Android.media.AudioRecord classes obtain the audio-frequency information of source of sound.
Step S102, the difference of vibration in the audio-frequency information of the preset length is determined.
Amplitude refers to the ultimate range of deviation origin-location during object vibrations, the loudness and source of sound of the sound that human ear is heard
Amplitude it is related, amplitude is bigger, and loudness is stronger.In one embodiment, obtained DAB letter can be decoded to audio decoder
Number it is sampled, obtains amplitude information, wherein, the amplitude information can be made up of multiple amplitudes, according to obtained multiple amplitudes
Value can determine difference of vibration accordingly.Exemplary, by taking 3s as an example, in the source of sound played in 3s durations, corresponding obtained audio letter
Multiple amplitudes in breath, the peak swing value and minimum amplitude value of acquisition are recorded, by peak swing value and minimum amplitude value
Difference be defined as the preset length audio-frequency information difference of vibration.
In one embodiment, when detecting source of sound broadcasting, determined every preset time (such as 1s, 3s or 10s) once pre-
If the audio-frequency information of length, or in real time, the amplitude of each frame of audio-frequency information is determined, when reaching preset length
Determine difference of vibration.Specifically, the audio-frequency information for obtaining the source of sound includes：The preset length for obtaining the source of sound
Audio-frequency information includes：Obtain the audio frame information of the preset length of the source of sound；Accordingly, it is described to determine the preset length

Audio-frequency information under each frame determine corresponding to amplitude, and then determine difference of vibration.
Step S103, judge whether the difference of vibration meets preparatory condition, if it is, performing step S104, if not
Then perform step S105.
In one embodiment, the difference of vibration meets that preparatory condition includes：The difference of vibration is more than default difference of vibration.Show
The default difference of vibration of example property can be 0.2db.When amplitude difference is bigger, it is meant that source of sound play when sound highest volume and
Minimum volume difference is larger so that user sounds wave volume big rise and fall, loftier.
Step S104, the amplitude of the source of sound is adjusted.
In one embodiment, the amplitude to the source of sound be adjusted including：To being more than the in the source of sound
One amplitude threshold and size less than the amplitude of the second amplitude threshold are adjusted.Wherein, the first amplitude threshold is shaken more than second
