Generally, different audio output units has different frequency response curves when audio-frequency information is presented, and the frequency response is bent
Line refers to the curve that gain changes with frequency.Preferable frequency response curve should be straight, and voice signal does not produce mistake after
Very, such amplifier is fewer for the influence of signal, and amplifier is under different power outputs, its frequency response be it is different,
Usual power output is bigger, and its frequency response index is poorer.For example, 1 ten times of amplifier, the multiplication factor to 1KHz signal is
10 times, and the possible multiplication factor of AC signal for 10KHz has reformed into 9.99 times, then, we are just it may be said that this puts
Big device generates frequency distortion.

The filter audio information exported after ripple device is represented with x (n), gathers at least section audio section in the filter audio information, i.e.,
At least one sampled audio section is determined from the filter audio information, the subframe energy of each sampled audio section is calculated, it is described
Subframe energy represents that the calculation formula of the subframe energy is as follows with E (m)：
In formula 1, XHPF(n) it is to pass through the High frequency filter audio-frequency information that high-pass filter filters out low-frequency component, n is height
The sampled audio frame of frequency filter audio information middle pitch frequency range, m is m-th of audio frame in the audio section of sampling, and m is positive integer,
And m=1,2 ... b, L are the frame length of the audio frame in the audio section of collection, b represents the frame of the audio frame included in audio section
Number.
Energy when calculating long further according to the subframe energy, energy can use E when described longLT(m) represent, its calculation formula
It is as follows：
ELT(m)=(1-a) ELT(m-1)+aE(m) (2)
In formula 2, m, b are positive integer, and m=1,2 ... b, 0<a<1.
Obtain the subframe energy value and it is described long when energy value after, the relatively value and the length of the subframe energy
Shi Nengliang value, if E (m) >=ρ × ELT(m), then the parameter value of the transient state sign parameter is 1, otherwise the transient state sign
The parameter value of parameter is 0.Wherein, ρ is the positive number less than 1.
Wherein, the filter audio corresponding with the audio-frequency information to be output is being obtained by the high-pass filter
Information, and according to the subframe energy of the filter audio information determine corresponding sampled audio frame transient state indicate parameter after, also
The transient state of smooth next frame can be gone to indicate parameter by smearing algorithm, the smearing algorithm can be used for the smooth filtering letter
The parameter value of adjacent subframe energy in breath, so that the transient state sign parameter of the audio frame in the filtering information keeps one
Cause, if for example, the parameter value of the transient state sign parameter of current audio frame is 1, then the transient state sign parameter of next audio frame
Parameter value be similarly 1.
, can will be described to be output if the characteristic parameter is the frequency domain energy parameter in the embodiment of the present invention
Audio-frequency information be transformed into frequency domain, with the parameter value for the frequency domain energy parameter for determining the audio-frequency information to be output.
For example, the audio-frequency information to be output be s (n), convert it to frequency domain, can obtain with it is described to be output
The value of frequency point of the corresponding frequency-domain audio information of audio-frequency information, is represented with y (k), then can just be counted according to the frequency-domain audio information
The frequency domain energy parameter of the audio-frequency information to be output is calculated, is represented with E (k).The frequency domain of the audio-frequency information to be output
The calculation formula of the parameter value of energy parameter can be as follows：
In formula 3, y (k) is the value of frequency point of frequency-domain audio information, and k is the frequency gathered in frequency-domain audio information, and p is small
In L/2 positive integer, L for the audio frame in the audio section of collection frame length.
, can be according to described to be output if the characteristic parameter is the peak-to-average force ratio parameter in the embodiment of the present invention
