The frequency response point of adjustment of one audio file is 3, respectively A, B and C, wherein, the regulated value on A points is 3 units of regulation downwards,
To adjust downwards 5 units, the regulated value on C points is to be adjusted up 9 units to regulated value on B points, then according to the first audio frequency
When regulated value in each frequency response point of adjustment of file is adjusted to each frequency response point of adjustment of the first audio file, can be by A
Point adjusts downwards 3 units, B points is adjusted downwards 5 units, C points are adjusted up 9 units.
Available second audio file is adjusted by each the frequency response point of adjustment to the first audio file.Wherein,
The form of two audio files can be WMA (Windows Media Audio, Microsoft's audio format), AMR (Adaptive
Multi-Rate, adaptive multi-rate coding), MP3 (Moving Picture Experts Group Audio Layer
3) etc. III, the present embodiment does not make specific limit to the form of the second audio file to dynamic image expert's compression standard audio frequency aspect
It is fixed.The size of the second audio file can be for 20K, 300K etc., and this enforcements equally is not made specifically to the size of the second audio file
Restriction.
In step 204, the phase place by the phase place of the second audio file with the first audio file is compared, according to comparing
As a result judge whether the phase place of the second audio file changes with respect to the phase place of the first audio file, if change, performs step
Rapid 205.
In order to improve the audiovisual experience effect of user, make the audio of the audio file of broadcasting better, to the first sound
After each frequency response point of adjustment of frequency file is adjusted, the method that the present embodiment is provided also will determine that second obtained after adjusting
Whether the phase place of audio file changes with respect to the phase place of the first audio file.If the phase place of the second audio file is with respect to first
After the phase place change of audio file, then the phase place of the second audio file can be adjusted by subsequent step.Specifically, exist
When judging whether the phase place of the second audio file changes relative to the phase place of the first audio file, can be by the second audio file
Phase place be compared with the phase place of the first audio file, and then judge that the phase place of the second audio file is relative according to comparative result
Whether the phase place of the first audio file changes.
In step 205, the phase place of the second audio file is adjusted according to the phase place of the first audio file, obtains
Three audio files, and using the 3rd audio file as the result that audio regulation is carried out to the first audio file.
As the phase place of relative first audio file of the phase place that the second audio file is will determine that out in above-mentioned steps 204 is sent out
Changing, therefore, in order to improve the experience effect of user, making that the audio of the audio file of broadcasting is better, this step is upper
On the basis of stating step 204, the phase place of the second audio file is adjusted according to the phase place of the first audio file.By to
The phase place of two audio files is adjusted available 3rd audio file, and the 3rd audio file is to enter the first audio file
The result that row audio is adjusted.So far, realized by above-mentioned steps and the audio of the first audio file to be regulated is adjusted.
It should be noted that what said process was only illustrated so that the audio to the first audio file is adjusted as an example, for
The audio of other audio files adjusts process and can refer to the above-mentioned regulation process to the first audio file, and here is omitted.
Alternatively, when the audio after according to regulation is played out, in order to avoid the audio played causes damage to loudspeaker,
The method that the present embodiment is provided, is gone back using the 3rd audio file as after the result that audio regulation is carried out to the first audio file
Gain-adjusted will be carried out to the 3rd audio file according to the corresponding gain ranging of predetermined each loudspeaker, so as to obtain each
Corresponding 4th audio file of loudspeaker, and then corresponding 4th audio file of each loudspeaker is played by each loudspeaker.
Wherein, the corresponding gain ranging of each loudspeaker can be 10dB (decibel, decibel)～20dB, 30dB～50dB
Specific restriction is not made to the corresponding gain ranging of each loudspeaker Deng, the present embodiment.It is corresponding with regard to predefining each loudspeaker
The mode of gain ranging, including but not limited to determines corresponding gain for each loudspeaker previously according to the performance parameter of each loudspeaker
Scope.Wherein, the performance parameter of each loudspeaker includes but is not limited to rated power, rated impedance, temperature coefficient, frequency response amplitude
Deng the present embodiment specific restriction of performance parameter work not to each loudspeaker.Specifically, in the performance parameter according to each loudspeaker
When determining corresponding gain ranging for each loudspeaker, including but not limited to：First, by the rated power of each loudspeaker, specified work(
The fitting of the performance parameters such as rate, temperature coefficient, frequency response amplitude obtains a curve；Secondly, obtain value on the peak of curve and
Value in minimum point；Again, using the value in the minimum point of curve as gain minima, using the value on the peak of curve as
Gain maximum.After the corresponding gain minima of each loudspeaker and gain maximum is obtained, can be according to each loudspeaker correspondence
Gain minima and gain maximum determine the corresponding gain ranging of each loudspeaker.For example, according to the performance parameter of loudspeaker A it is
Loudspeaker A determines that corresponding gain ranging is 30dB～60dB, determines corresponding gain for loudspeaker B according to the performance parameter of loudspeaker B
Scope is 50dB～100dB.
Alternatively, when corresponding gain ranging is determined for each loudspeaker according to the performance parameter of each loudspeaker, if loudspeaker A
It is identical with the performance parameter of loudspeaker B, then identical gain ranging can be determined for loudspeaker A and loudspeaker B, can such as be loudspeaker A and loudspeaker B
Corresponding gain ranging is determined for 10dB～30dB etc.；If loudspeaker A is different with the performance parameter of loudspeaker B, can be loudspeaker A and loudspeaker
B determines different gain rangings, such as can determine corresponding gain ranging for 25dB～40dB for loudspeaker A, and it is right to be that loudspeaker B determines
The gain ranging answered is 35dB～60dB etc..
Alternatively, as each loudspeaker can produce heat during the 4th audio file is played, and work as each loudspeaker
Play the 4th audio file yield value it is bigger when, it is more that each loudspeaker plays the heat that the 4th audio file produces.And each
The heat produced during loudspeaker four audio file of broadcasting is more, and the temperature of each loudspeaker is higher, while the damage degree to loudspeaker
It is bigger.And when hour is got in the gain that each loudspeaker plays the 4th audio file, each loudspeaker plays the heat that audio file is produced
Fewer, the temperature of each loudspeaker is lower, at the same it is less to the damage degree of loudspeaker, but when each loudspeaker plays the 4th audio file
Yield value it is too small when, by cause each loudspeaker broadcast the 4th audio frequency volume it is relatively low, so as to have influence on the audio experience of user.Cause
This, in order to avoid each loudspeaker is damaged to loudspeaker because gain is excessive when four audio files is played, while not affecting
To user audio experience on the premise of, the method that the present embodiment is provided is playing each loudspeaker corresponding the by each loudspeaker
During four audio files, the yield value of the 4th audio file played to each loudspeaker is needed to be adjusted.Specifically, can be by such as
Under type is realized：
First, during corresponding 4th audio file of each loudspeaker is played by each loudspeaker real-time reception each
The voltage signal and current signal of loudspeaker feedback；
Wherein, with regard to the real-time reception during corresponding 4th audio file of each loudspeaker is played by each loudspeaker
The mode of the voltage signal and current signal of each loudspeaker feedback, the present embodiment do not make specific restriction.When being embodied as, can root
The voltage signal and current signal of each loudspeaker feedback are received according to the physical device being connected with each loudspeaker.
Secondly, the 4th for each loudspeaker being played according to the voltage signal and current signal of each the loudspeaker feedback for receiving
The yield value of audio file is adjusted.
Specifically, for each loudspeaker being played according to the voltage signal and current signal of each loudspeaker feedback for receiving
The mode that the yield value of four audio files is adjusted, including but not limited to：
The corresponding gain-adjusted parameter of each loudspeaker is determined according to the voltage signal and current signal of each loudspeaker feedback, and
Gain ranging each loudspeaker corresponding gain-adjusted parameter corresponding with each loudspeaker is compared；
If the corresponding gain-adjusted parameter of arbitrary loudspeaker is higher than the maximum of the corresponding gain ranging of arbitrary loudspeaker, will appoint
The yield value of the 4th audio file that one loudspeaker are played is turned down；
If the corresponding gain-adjusted parameter of arbitrary loudspeaker is less than the minima of the corresponding gain ranging of arbitrary loudspeaker, will appoint
The yield value of the 4th audio file that one loudspeaker are played is heightened.
Wherein, with regard to determining that the corresponding gain of each loudspeaker is adjusted according to the voltage signal and current signal of each loudspeaker feedback
The mode of JIESHEN number, the present embodiment do not make specific restriction.When being embodied as, the voltage signal that can be returned according to each loudspeaker and
The relational expression of current signal gain-adjusted parameter corresponding with each loudspeaker is determined.
For said process, in order to make it easy to understand, explanation explained in detail will be carried out with a specific example below.
By taking loudspeaker A as an example, the maximum of the corresponding gain rangings of loudspeaker A is set as 60dB, the corresponding gain rangings of loudspeaker A
Minima be 20dB, the i.e. corresponding gain rangings of loudspeaker A be 20dB～60dB.If according to loudspeaker A feedback voltage signal and
Current signal determines the corresponding gain-adjusted parameters of loudspeaker A for 70dB, by each loudspeaker corresponding gain-adjusted parameter with it is every
When the corresponding gain ranging of individual loudspeaker is compared, as the corresponding gain-adjusted parameters of loudspeaker A are higher than the corresponding gains of loudspeaker A
The maximum of scope, accordingly, it would be desirable to the yield value of the 4th audio file that loudspeaker A is played is turned down；If according to loudspeaker A feedbacks
Voltage signal and current signal determine that the corresponding gain-adjusted parameters of loudspeaker A are 15dB, and each loudspeaker corresponding gain is being adjusted
When JIESHEN amount gain ranging corresponding with each loudspeaker is compared, as the corresponding gain-adjusted parameters of loudspeaker A are less than loudspeaker A
The minima of corresponding gain ranging, accordingly, it would be desirable to the yield value of the 4th audio file that loudspeaker A is played is heightened.
It should be noted that it is above-mentioned when corresponding four audio file of each loudspeaker is played by each loudspeaker, the 4th
Audio file is played out in real time, and the yield value of the 4th audio file played to each loudspeaker is adjusted being according to reality
