Specific embodiment
Illustrated below in conjunction with accompanying drawing preferred embodiment of this disclosure, it will be appreciated that preferred reality described herein
Apply example and be merely to illustrate and explain the disclosure, be not used to limit the disclosure.
The embodiment of the present disclosure provides a kind of audio-frequency processing method, and the audio-frequency processing method can be realized in terminal device,
Such as mobile phone, panel computer, computer.The disclosure is described in detail below in conjunction with accompanying drawing.
In one embodiment, as shown in figure 1, audio-frequency processing method includes：
In step S101, when receiving audio, the audio-frequency information of audio is obtained.
Wherein, a kind of information in the frequency domain information of time-domain information and the audio of the audio-frequency information at least including the audio.
Wherein, the audio for receiving can be segmented and is obtained successively, the audio that will for example receive is according to 10ms（In the least
Second）For one section is divided, according to time order and function, it is one section with 10ms successively and obtains audio fragment, then the audio to obtaining
Fragment is analyzed and adjusts.
In step s 102, the audio-frequency information to audio is analyzed, and determines the audio frequency characteristics of audio.
Wherein, any one or more in tone color, tone, loudness of the audio frequency characteristics including audio.Audio is by many frequencies
The composite signal of the different component signal composition of rate, fundamental tone and overtone in audio determine tone color, and the frequency of audio is determined
Tone, the amplitude of audio determine loudness.In the audio-frequency information of acquisition
Wherein, audio frequency characteristics can also be based on Model in Time Domain, general model, the cepstrum coefficient LPCC based on LPC, be based on
The cepstrum coefficient MFCC of Mel frequencies bending, perception linear predictor coefficient and the audio frequency characteristics based on determinations such as chaos fractal theories.
Wherein it is determined that the audio frequency characteristics of audio, there is following two implementations：
Mode one：
Step A：When the time-domain information that audio-frequency information is the audio, by Fourier transformation, by the time-domain information of audio
It is transformed to the frequency domain information of audio.
Step B：Frequency domain information to audio is analyzed, and determines the audio frequency characteristics of audio.

Tone including audio.
In step S203, according to the tone of audio, the weighted value of audio is determined.
In step S204, according to the weighted value, the tone of the audio is adjusted.
For example, a comfortable range of pitch can be pre-configured with, user is comfortable in the comfortable range of pitch,
Will not think that sound is ear-piercing will not also think that sound is stuffy.When the tone of audio is not in the comfortable range of pitch, can be with
By to one weighted value of the audio setting, by the tone regulation of audio to the comfortable range of pitch.But it is different after regulation
Tone it is still different, in order to also be differed after causing different tones outputs, user can not only recognize the difference of tone,
And heard in comfortable range of pitch.As shown in figure 3, the signal changed with time for the tone of the audio in 10ms
Figure, dotted line a and dotted line b represent the comfortable range of pitch of the sense of hearing, wherein tone of the tone of a less than b in figure.To Fig. 3 middle pitches
After the tone of frequency is weighted calculating, the design sketch of the tone output of audio is as shown in Figure 4.Figure 4, it is seen that in 10ms
The tone of audio retains original difference, but audio tone all in comfortable range of pitch.
In step S205, the audio after output regulation tone.
In the embodiment of the present disclosure, the tone according to audio dynamically determines the weighted value of the audio in real time, realizes in real time
According to the tone of audio, the tone of dynamic adjustment audio so that the result of audio can more meet the demand of user, improve
The quality of the audio of output.
