Specific embodiment be described in detail, above and other purpose of the invention, feature and advantage will be become apparent from.Complete
Identical reference indicates identical part in portion's accompanying drawing.Not deliberately accompanying drawing drawn to scale, it is preferred that emphasis is show this hair
Bright purport.
Referring to Fig. 1, a kind of flow chart of audio play control method first embodiment that the figure is provided for the present invention.
In the present embodiment, including：
S101：Monophonic audio is obtained, as the first audio；

One audio is exported according to the described first right audio output intensity level in R channel.
When processing mono audio file, monophonic audio is got first, as the first audio.
In the voice data, the parameters such as intensity of sound (decibel) value of monophonic audio can be got.
For monophonic audio, in the absence of the problem of multiple sound source datas.Therefore, control is played out in left and right acoustic channels
When processed, audio frequency process all also is carried out to the monophonic audio for getting.Specifically, the intensity of sound value of the first audio is obtained, will
The numerical value and specified left position angle multiplication, are calculated and produce a numerical value, and the audio of audio is exported as left audio
Intensity level.
Meanwhile, in order to build the stereophonic effect of multichannel audio, in addition it is also necessary to which right audio channel is processed.Cause
This left audio has been enhanced or has weakened, thus right audio channel the result of broadcast broadcasting that then needs with left audio
Effect is opposite.Specifically, by the intensity of sound of the first audio and right position angle multiplication, to obtain R channel output audio
Audio intensity value.

Relation carries out correspondence.
If target source of sound is on the left side of the coordinate system longitudinal axis, referring to Fig. 2A and 2B, then with the angle value and vertical angle
Ratio based on, the audio intensity interval (1,2] in value.
In fig. 2, the position of target source of sound is 135 degree, the left position in the longitudinal axis.By 135 degree of ÷ 90 degree=1.5,
It is 1.5 to obtain left position angle bottom coefficient.In fig. 2b, the position of target source of sound is -135 degree, is also at the left side of the longitudinal axis
- 135 degree ÷ -90 are spent=1.5 by position, that is, it is 1.5 to obtain left position angle bottom coefficient.
If the target audio is on the right of the coordinate system longitudinal axis, referring to Fig. 3 A and 3B, then with the angle value with
Based on the ratio of vertical angle, the audio intensity interval [0,1) in value.
In figure 3 a, the position of target source of sound is 45 degree, the location right in the longitudinal axis.By 45 degree of ÷ 90 degree=0.5, i.e.,
It is 0.5 to obtain left position angle bottom coefficient.In figure 3b, the position of target source of sound is -45 degree, is also at the position on the right of the longitudinal axis
Put, -45 degree ÷ -90 are spent=0.5, that is, it is 0.5 to obtain left position angle bottom coefficient.
If the target audio is on the coordinate system longitudinal axis, referring to Fig. 4 A and 4B, 90 degree of ÷ 90 degree=1 or -90 spend
÷ -90 degree=1, value is 1.
After above-mentioned left position angle coefficient is obtained, then it is calculated right position angle coefficient.
Finally, export the first audio according to the left audio intensity level that is calculated in L channel, R channel according to
The right audio channel intensity level being calculated exports the first audio.
By using above method, the two-channel stereo voice output to single audio frequency is capable of achieving, improves the audiovisual body of user
Test, while also not recorded with binaural format necessarily in audio recording, reduce recording cost.
