Specific embodiment
The exemplary embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
It is limited.It is to be able to thoroughly understand the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention
It is fully disclosed to those skilled in the art.
Fig. 1 is a kind of step flow chart of method of canceling noise provided in an embodiment of the present invention, as shown in Figure 1, this method
May include:
Environmental audio information in step 101, acquisition for mobile terminal current environment.
Noise is that pitch and loudness of a sound variation are chaotic, sounds disharmonic sound, is also possible to irregular by sounding body
The sound generated is vibrated, noise interferes people normally to rest, and generates interference to the sound to be listened of user.
In embodiments of the present invention, mobile terminal usage scenario relevant to audio at least may include: audio recording field
Scape and audio play scene.For audio recording scene, refer to that mobile terminal obtains the recording in current scene by microphone
Audio, the recorded audio may include the sound that ambient sound and when User Activity generate in current scene；Field is played for audio
Scape refers to that mobile terminal by earpiece, plays the audio got, which can be any one audio.
Specifically, environment is more noisy if recording for audio recording scene, noise in the audio recorded and obtained will lead to
It is larger, influence the quality of audio recording.It is recorded for scene for most of, the noise in recording audio is usually to record environment
In environmental audio information the ambient sound in recording audio can be eliminated, be reached to reach higher recording quality
The purpose of noise in recording audio is greatly lowered.
In this step, the embodiment of the present invention can control microphone based on the mobile terminal for using low-power chip
State is maintained a normally open, obtains the environmental audio information in mobile terminal local environment in real time, and the environmental audio information is stored
In the terminal.
Step 102, mobile terminal determine the first audio-frequency information in the environmental audio information.
In embodiments of the present invention, since microphone is in acquisition environmental audio information in real time, so within a certain period of time, meeting
Multiple environmental audio information are generated, in order to reach better noise eradicating efficacy, can determine in multiple environmental audio information
One audio-frequency information, first audio-frequency information can be understood as and the immediate sound of noise in recording audio.
Determine the first audio-frequency information specific implementation can there are many, in a kind of implementation of the embodiment of the present invention
In, it can will receive the environmental audio information that the operation for actively opening microphone generates before and determine that the first audio is believed
Breath.It, can also be corresponding according to being generated when creating environmental audio information in another implementation of the embodiment of the present invention
Environmental labels voluntarily select an environmental audio information to determine that the first audio-frequency information e.g. creates by user according to environmental labels
The corresponding relationship of multiple environmental audio information and environmental labels: audio 1-is indoor, 2-auditorium of audio, 3-basement of audio, uses
If family is wanted to eliminate the influence of the noise in auditorium recording audio, can choose audio 2 is the first audio-frequency information.
Step 103, it after mobile terminal receives the operational order for actively opening microphone, is obtained by the microphone
Take the second audio-frequency information.
In embodiments of the present invention, when user needs to carry out recording operation, the processor of mobile terminal can receive master
The dynamic operation for opening microphone, and microphone unlatching is controlled, the acquisition operation of audio-frequency information is carried out, by taking recording as an example: microphone
Acquisition starts recording to the audio-frequency information at each time point during terminating, and obtains the second audio-frequency information.
Step 104, mobile terminal eliminates first audio-frequency information in second audio-frequency information.
In embodiments of the present invention, sound is also a kind of wave, can be in various Propagations, and therefore, sound wave is also competent
It relates to, if utilizing the feature of sound wave interference, so that it may the interference of the sound waves of some noises is balanced out (or at least reduce width
Degree).Using this point, the embodiment of the present invention can eliminate noise using the method offset.
Specifically, the elimination of noise may include: by generate it is identical as the opposite in phase of the first audio-frequency information, amplitude or
Similar reversed sound wave, reversed sound wave and the second audio-frequency information are neutralized, to eliminate first in the second audio-frequency information
Audio-frequency information realizes the effect of noise reduction.
Therefore, the embodiment of the present invention is directed to all second audio-frequency informations recorded by mobile terminal, may be by recording
System before obtain environmental audio information carry out noise Processing for removing, can be adapted for it is all by mobile terminal recording audio, no
It needs to carry out spectrum analysis for specific audio.
To sum up, a kind of method of canceling noise provided in an embodiment of the present invention, comprising: obtain the environment in current environment
Audio-frequency information；In environmental audio information, the first audio-frequency information is determined；Receive actively open microphone operational order it
Afterwards, the second audio-frequency information is obtained by microphone；Eliminate the first audio-frequency information in the second audio-frequency information, the present invention to by
The environmental audio information obtained before recording carries out audio neutralization with the second audio-frequency information that mobile terminal is recorded, utilizes sound wave
Principle of interference achievees the purpose that, to the progress noise elimination of the second audio-frequency information, the present invention is suitable for passing through mobile terminal to all
Recording audio carries out noise elimination, does not need to carry out spectrum analysis for specific audio, simplifies noise treatment process, improves
Treatment effeciency.
