Embodiment one
Fig. 1 is the schematic flow sheet of the method for the volume adjusting that the embodiment of the present invention one is provided.As shown in figure 1, the method
Specifically include following steps：
101：Obtain the original sound volume of audio-video document to be played.
The audio-video document to be played can be the audio or video file of various forms, such as MP3, WAV, WMA,
The audio file of the forms such as CDA, MID, or the form such as MP4, AVI, WMV, MPEG video file.
The voice data of the audio-video document can be analyzed, obtain the original sound volume of the audio-video document.
102：The first regulation coefficient to the original sound volume is determined according to reference volume.
In the present embodiment, the reference volume can be default volume.For example, being adapted to the medium volume of human ear about
It is 50~70dB, the reference volume can be arranged in the range of 50~70dB, for example, is set to 60dB.
The reference volume can be as needed configured by user.For example, user can be accustomed to according to personal reception
The reference volume of larger (such as 70dB) or smaller (such as 50dB) is set.
In another embodiment, the reference volume can be obtained according to the audio-video document specified.For example, can obtain
The average volume of the audio-video document specified, the average volume of the audio-video document that this is specified is used as the reference volume.
The reference volume can also determine according to the system sound volume of electronic equipment.
It is described to determine that to the first regulation coefficient of the original sound volume be according to the audio frequency and video according to reference volume
The original sound volume of file calculates the average volume of the audio-video document, is determined with the average volume according to the reference volume
To the first regulation coefficient of the original sound volume.For example, the reference volume is Q, the average volume of the audio-video document is
Q1, then first regulation coefficient can be Q/Q1.
First regulation coefficient can be more than 1, the original sound volume for improving the audio-video document.Described first adjusts
Integral coefficient can also be less than 1, the original sound volume for reducing the audio-video document more than 0.
103：Judge the original sound volume of audio in the preset period of time that will be played in the audio-video document through described
Whether the volume of one regulation coefficient adjustment is being preset in volume range, if not, it is determined that the preset period of time corresponding second is adjusted
Integral coefficient.
The maxima and minima of volume can be set, and the default volume range is defined as greater than being equal to the minimum value
And less than or equal to the maximum.
In the present embodiment, it can be determined that the audio in preset period of time that will be played in the audio-video document it is original
Whether volume is more than the maximum of the default volume range through the volume that first regulation coefficient is adjusted, if the audio frequency and video
The original sound volume of the audio in preset period of time that will be played in file is more than institute through the volume that first regulation coefficient is adjusted
The maximum of default volume range is stated, then using the value after first regulation coefficient reduction as the preset period of time corresponding the
Two regulation coefficients.The original sound volume of audio in the preset period of time that will be played in the audio-video document can be calculated through described

104：Original sound volume according to the audio in second regulation coefficient and the preset period of time plays described pre-
If the audio in the period.
Sometimes more than max volume or shorter less than the time of minimal volume, in order to avoid sound variation is too lofty,
In the embodiment of the present invention, volume is gradually adjusted in correlation time region, or begin to gradually become before relevant range is entered
Change volume, such as：There is the time point A more than max volume, at first 2 seconds of A, begin to be gradually reduced amplification coefficient and (now adjust
Integral coefficient is amplification coefficient), the amplification coefficient of A points is reached exactly to when to A, 2 after A second, then be gradually increased and put
Big coefficient is until the average amplification coefficient of arrival audio.
In the present embodiment, first regulation coefficient can be gradually adjusted to described in the preset period of time
The mode of the second regulation coefficient is adjusted and plays to the original sound volume of the audio in the preset period of time.
In another embodiment, can be in the preset period of time, with second regulation coefficient to the preset period of time
Interior audio is played out.
The method of the volume adjusting of embodiment one obtains the original sound volume of audio-video document to be played；According to reference volume
It is determined that to the first regulation coefficient of the original sound volume；Judge the sound in the preset period of time that will be played in the audio-video document
Whether the original sound volume of frequency is being preset in volume range through the volume that first regulation coefficient is adjusted, if not, it is determined that described
Corresponding second regulation coefficient of preset period of time；According to the original of the audio in second regulation coefficient and the preset period of time
Volume plays the audio in the preset period of time.Embodiment one can be to sound too high or too low in audio-video document to be played
Amount is adjusted, and improves user's listening experience.
In another embodiment, methods described can also include：If will be played in the audio-video document it is default when
The volume that the original sound volume of the audio in section is adjusted through first regulation coefficient in the default volume range, then according to institute
State the audio that the original sound volume of the audio in the first regulation coefficient and the preset period of time is played in the preset period of time.
