Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present disclosure is described, should be appreciated that preferred embodiment described herein is only for the description and interpretation disclosure, and be not used in the restriction disclosure.
Disclosure embodiment provides a kind of audio-frequency processing method, and this audio-frequency processing method can be realized in terminal device, as mobile phone, panel computer, computer etc.Below in conjunction with accompanying drawing, the disclosure is elaborated.
In one embodiment, as shown in Figure 1, audio-frequency processing method comprises:
In step S101, while receiving audio frequency, obtain the audio-frequency information of audio frequency.
Wherein, audio-frequency information at least comprises a kind of information in the time-domain information of this audio frequency and the frequency domain information of this audio frequency.
Wherein, the audio frequency receiving can be obtained successively in segmentation, for example by the audio frequency receiving according to 10ms(millisecond) be one section and divide, according to time order and function, the 10ms of take successively obtains audio fragment as one section, then the audio fragment obtaining is analyzed and is regulated.
In step S102, the audio-frequency information of audio frequency is analyzed, determine the audio frequency characteristics of audio frequency.
Wherein, audio frequency characteristics comprises any one or more in the tone color, tone, loudness of audio frequency.Audio frequency is the composite signal being comprised of the different component signal of many frequencies, fundamental tone and overtone in audio frequency have determined tone color, and the frequency of audio frequency has determined that the amplitude of tone, audio frequency has determined loudness.In the audio-frequency information obtaining
Wherein, audio frequency characteristics can also be based on Model in Time Domain, fall general model, cepstrum coefficient LPCC based on LPC, cepstrum coefficient MFCC based on the bending of Mel frequency, perception linear predictor coefficient and based on definite audio frequency characteristics such as chaos fractal theories.
Wherein, determine the audio frequency characteristics of audio frequency, have following two kinds of implementations:
Mode one:
Steps A: when time-domain information that audio-frequency information is this audio frequency, by Fourier transform, the time-domain information of audio frequency is transformed to the frequency domain information of audio frequency.
Step B: the frequency domain information to audio frequency is analyzed, determines the audio frequency characteristics of audio frequency.
