Line A is the intrinsic frequency response curve of output of electronic equipment, can be known by curve A, for each Frequency point electronic equipment institute
The maximum gain that can be exported, if most being increased by the enhanced gain of audio greater than what electronic equipment can be output at the frequency
Benefit, due to the limitation on electronic equipment hardware, it will cause output to be distorted, influence audio effect.
In addition, the first audio enhancement method is, for example, bass boost, then then can be to the increasing of the frequency corresponding to bass
Benefit is adjusted, such as frequency range corresponding to bass is the frequency less than 500HZ, and N number of frequency can refer to 20HZ- at this time
480 frequencies included by 500HZ, i.e., the value of N is 480 at this time.
Step 102: the first frequency response curve of output is corresponding with the identical frequency institute in predetermined frequency response curve of output
Gain is compared, to determine the second frequency response curve of output according to comparison result；Wherein, predetermined frequency response curve of output sets for electronics

Shown in curve A in 2, at 100HZ, it is seen that the corresponding gain of curve B (97dB) is greater than the corresponding gain of curve A (90dB),
So export distortion at 100HZ in order to avoid audio signal at this time, then it can be using 90dB as in the second frequency response curve of output
The corresponding gain of 100HZ, for example, by using second frequency response curve of output such as Fig. 3 of the acquisition after the scheme in the embodiment of the present invention
In curve C shown in, that is to say, that can by gain be greater than predetermined frequency response curve of output in gain Frequency point gain all
The gain being reduced in predetermined frequency response curve of output, such as the curve C in Fig. 3, the gain of the frequency near 100HZ is all by song

The enhanced gain of audio can be directly used to be exported, to guarantee the effect of audio enhancing as far as possible.
Continue by taking Fig. 2 as an example, such as at 1KHZ, the corresponding gain hypothesis of curve A is 93dB, and the corresponding increasing of curve B
Benefit is assumed to be 84dB, then at this time can be directly using 84dB as the frequency at 1KHZ in the second frequency response curve of output.
The third situation:
If the first gain of the first frequency in the first frequency response curve of output is less than first in predetermined frequency response curve of output
Second gain of frequency, then using the second gain as the gain of the first frequency in the second frequency response curve.
Alternatively, when carrying out the gain after audio enhancing without departing from the maximum gain that electronic equipment can export, in order to
The effect of audio enhancing is further promoted, the maximum gain that electronic equipment can be exported is exported as the second frequency response
The gain of first frequency in curve.
Continue by taking Fig. 2 as an example, such as at 1KHZ, the corresponding gain hypothesis of curve A is 93dB, and the corresponding increasing of curve B
Benefit is assumed to be 84dB, then in a third situation, can directly using 93dB as 1KHZ in the second frequency response curve of output at
Frequency.

If the first gain of the first frequency in the first frequency response curve of output is less than first in predetermined frequency response curve of output
Second gain of frequency, then using between any gain stated between the first gain and the second gain as in the second frequency response curve
The gain of first frequency.
Continue by taking the example in the third situation as an example, it can be using any gain between 84dB and 93dB as the
The gain of first frequency in two frequency response curves of output, such as using 88dB or 90dB as first in the second frequency response curve of output
The gain of frequency.
Optionally, first frequency can be any one frequency in M frequency, such as by taking Fig. 2 as an example, first frequency can
To be any one frequency in 20HZ-20KHZ.
Optionally, first frequency can be any one frequency in N number of frequency, it is assumed that the first audio enhancement method is used for
Audio enhancing is carried out to the gain of the bass part of 20HZ-500HZ, then first frequency can be any in 20HZ-500HZ
One frequency is the equal of being operated for the targeted frequency of the first audio enhancement method, and specific aim is stronger.
In the embodiment of the present invention, when electronic equipment carries out audio increasing to the first voice data stream with the first audio enhancement method
When strength is managed, the first frequency response curve of output can be obtained, i.e. the first frequency response curve of output be according to the first audio enhancement method into
Row enhancing treated frequency response curve of output, further, electronic equipment is intrinsic by the first frequency response curve of output and electronic equipment
Frequency response curve of output (i.e. predetermined frequency response curve of output) be compared, be the identical frequency that will include in the two specifically
Ingredient the value of corresponding gain carry out size comparison, and then determine the second frequency response curve of output further according to comparison result,
Finally the first voice data stream is exported according still further to the second frequency response curve of output.
That is, electronic equipment can will pass through enhancing side before exporting to enhanced voice data stream
Formula carries out the enhanced frequency response curve of output frequency response curve of output intrinsic with electronic equipment and is compared, and then further according to comparing
As a result the second frequency response curve of output is obtained, and since the intrinsic frequency response curve of output of electronic equipment is the hardware feature of electronic equipment
Embodiment, the maximum gain that can be exported at each frequency with characterization of electronic equipment, if carry out enhancing treated increase
Benefit is greater than the maximum gain that can export, then will due to electronic equipment itself hardware limitation and cause output to be distorted, and
It, can be as far as possible by the hardware of electronic equipment itself during carrying out audio enhancing in technical solution in inventive embodiments
