Embodiment
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 is applicable to terminal
Situation about volume being adjusted during device plays source of sound, this method can be held by terminal device provided in an embodiment of the present invention
OK, the volume adjustment device of the terminal device can be realized by the way of software and/or hardware, as shown in figure 1, the present embodiment carries
The concrete scheme of confession is as follows：
Step S101, when detecting that terminal device carries out source of sound broadcasting, the audio-frequency information of the source of sound is obtained.
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 source of sound is obtained.In one embodiment,
The digital audio and video signals that can decode to obtain to audio decoder are sampled, and determine audio-frequency information corresponding to the source of sound.Another
In embodiment, the original document of currently playing source of sound can also be obtained, source of sound pair is determined by the parsing to the original document
The audio-frequency information answered.In another embodiment, by taking android system as an example, can pass through
Android.media.MediaRecorder classes or android.media.AudioRecord classes obtain the audio-frequency information of source of sound.
Step S102, the amplitude of the source of sound is determined according to the audio-frequency information.
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 the amplitude information in preset time period T, wherein, the amplitude information can be made up of multiple amplitudes, foundation
Obtained multiple amplitudes can determine the amplitude curve of the source of sound played in preset time period T accordingly.In another implementation
In example, 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.In another embodiment, when step S101 is got
Audio-frequency information be the amplitude that can obtain corresponding source of sound corresponding to source of sound during original document by being parsed to original document
Data, and then the amplitude data is defined as to the amplitude of source of sound.

After section condition, the data of the sign amplitude information in obtained voice data can be carried out by being parsed to audio files
Modification, is packaged again after modification, and when being buffered to corresponding audio files and being played, the amplitude of source of sound is corresponding
It is increased；It is also possible that in the decoding process that source of sound plays, shaken by being analyzed obtained digital audio and video signals
Width data, the amplitude data is multiplied by corresponding adjustment factor to change amplitude size, and then the volume of source of sound is adjusted.
Hereby it is achieved that being adjusted on the premise of not changing the original volume of terminal device system to the size of source of sound volume, adjust
Process can play load or in the source of sound in buffering area before audio files are introduced into buffering area to reduce
Appearance is adjusted to improve regulation efficiency.
In another embodiment, the amplitude size of each frame of source of sound is adjusted.Specifically, it is directed to during regulation
The difference of the amplitude size of each frame distributes different amplitude adjustment factors to carry out corresponding regulation, exemplary, specific corresponding
