S1: when described electronic equipment is connected with described audio frequency output attachments, utilizes auxiliary described the first audio collection unit, described the second audio collection unit to determine and intend gathering voice data and noise sound data.

S2: gather described plan and gather noise sound data described in voice data filtering.

Specifically, the electronic equipment in the embodiment of the present application comprises the first audio collection unit, as is arranged on the microphone of mobile phone bottom, is arranged on the microphone of panel computer sidepiece, or is arranged on the microphone etc. in the keyboard of notebook computer lower left corner.Electronic equipment can be connected with output audio with audio frequency output attachments, and in the embodiment of the present application, audio frequency output attachments has the second audio collection unit.Specifically, audio frequency output attachments can be common wired earphone, output audio after being connected with electronic equipment by data line, and the audio frequency that can gather by the data line input ear microphone of same group; Audio frequency output attachments can be also bluetooth earphone, by bluetooth and electronic equipment, set up wireless connections, electronic equipment by Bluetooth protocol by audio transmission to bluetooth earphone, bluetooth earphone output audio, microphone on bluetooth earphone gathers audio frequency simultaneously, by Bluetooth protocol, the audio frequency of collection is transmitted to telegram in reply subset again; Certainly, audio output apparatus can be also earphone, sound equipment of by WIFI, Zigbee etc., realizing connection etc., and the application does not do concrete restriction.In introduction below, will suppose that audio frequency output attachments is wired earphone, in specific implementation process, includes but not limited to wired earphone.

For when gathering audio frequency, can determine and intend gathering voice data and noise sound data, need to utilize the auxiliary of the second audio collection unit.In step S1, to utilize auxiliary the first audio collection unit, the second audio collection unit to determine and intend gathering voice data and noise sound data, detailed process is:

(1) utilize auxiliary described the first audio collection unit inspection in described the second audio collection unit to obtain the first angle that the first sound source vertical plane vertical with the placed side of described electronic equipment becomes.

Specifically, in the embodiment of the present application, in order determining, to intend gathering voice data and noise sound data, to need first electron gain equipment and the first sound source angulation, the namely angle of the vertical plane of the first sound source and placed side, electronic equipment place.For convenient, explain how the application obtains the first angle, the distance between hypothesis electronic equipment and the second audio collection unit is constant, please refer to Fig. 3 below.

In Fig. 3, continuous perpendicular bisector between the first audio collection unit and the second audio collection unit represents the vertical plane of electronic equipment placed side, in order to obtain the first angle, need to rotate two collecting units, so that two collecting units obtain many group acoustic informations, according to many groups acoustic information, determine the position of the first sound source, thereby obtain the first angle.

The initial position of supposing two audio collection unit is the horizontal linear in Fig. 4, by two audio collection finite element rotations time of one week, is T, and the sampling rate of two audio collection unit is 6kHz, and the length of a frame sound is M.So, rotate a circle collectable N frame voice data or N group voice data, wherein, N=6000T/M.Different owing to arriving the distance of the first sound source between the first audio collection unit and the second audio collection unit, so, the time that the voice signal of the first sound arrives the first audio collection unit and the second audio collection unit also can be different, so, utilize the mistiming of two audio collection unit of voice signal arrival of the first sound source, just can estimate the position of the first sound source, and then obtain the first angle.

Suppose in rotation two audio collection unit process of a week, gather N group voice data, the mistiming that every group of voice data arrives the first audio collection unit and the second audio collection unit is followed successively by t ₀, t ₁..., t _n-1.Below by the mutual pass function that calculates the voice data of the first audio collection unit collection and the data of the second audio collection unit collection, calculate mistiming t ₀, t ₁..., t _n-1.Because the processing for every group of data is identical, so below only with the 1st frame of collection, first group of voice data is that example is introduced.If a ₁be the data that the first audio collection unit collects, a ₂be the data that the second audio collection unit collects, by

$R_{12}=\left(\mathrm{\τ}\right)=\underset{n=0}{\overset{M-1}{\mathrm{\Σ}}}{a}_1\left(M\right)a_2(M-\mathrm{\τ})$ Formula 1

Calculate and obtain a ₁and a ₂mutual pass function.Wherein, τ is a ₁and a ₂phase differential.

Further by Fourier transform, formula 1 is transformed to frequency domain, convert:

$R_{12}=\left(\mathrm{\τ}\right)=\underset{n=0}{\overset{M-1}{\mathrm{\Σ}}}{A}_1\left(k\right)A_2(k-\mathrm{\τ})e^{j2\mathrm{\πk\τ}/M}$ Formula 2

The value that changes so τ just can calculate a plurality of R ₁₂(τ), wherein τ minimum gets 1, and maximal value is determined by the distance between the first audio collection unit and the second audio collection unit and the concrete velocity of sound.Finally, by

$t_1=\arg \left(\underset{\mathrm{\τ}}{\max }{R}_{12}\left(\mathrm{\τ}\right)\right)$ Formula 3

Calculate and obtain in first position, while namely gathering first group of voice data, the signal of the first sound source arrives the mistiming t of two audio collection unit ₁.All the other t ₂, t ₃..., t _n-1also by similar method, obtain.

Obtain time of arrival of each voice signal poor after, just can obtain the angle of the first sound source and two audio collection unit line perpendicular bisectors,

γ _i=arcsin (ct _i/ L) formula 4

Wherein, c sound propagation velocity now, L is two distances between audio collection unit, the γ calculating _ihave two values, one is the true estimated value of the first sound source and the angle γ of two audio collection unit line perpendicular bisectors _i1, also having one is the angle γ of mirror image estimated value and two audio collection unit line perpendicular bisectors _i2, by the known γ of geometric relationship _i1+ γ _i2=180 °.In addition, two audio collection unit are when gathering i group data, and the line of two collecting units and the angle of initial position are α _i=i360 °/N, i=0～N-1.

By above-mentioned calculating, can obtain the angle β of the first sound source actual position and initial position _i1angle β with mirror position and initial position _i2,

β _i1＝α _i+90°-γ _i1

β _i2=α _i+ 90 °-γ _i2, formula 5

Wherein, i=0,1 ..., N-1.Calculate the difference △ β between each angle of organizing the first sound source actual position and initial position and mirror position and the angle of initial position _i, mean value is done in the many groups estimated position that is less than threshold value, average bits is put the actual position of sound the most at last.

By above-mentioned algorithm, calculate the position that obtains the first sound source, and then with regard to the first angle between energy electron gain equipment and the first sound source, as shown in Figure 3.Specifically, in the embodiment of the present application, suppose that the first angle is specially the continuous perpendicular bisector in the first audio collection unit and the second audio collection unit and the angle angle of the first sound source, certainly, in specific implementation process, can directly use angle angle between the first audio collection unit and the first sound source as the first angle, concrete the application does not do concrete restriction yet.

Suppose by algorithm above, calculating and obtaining the first sound source perpendicular bisector angle between the first audio collection unit of electronic equipment and the second audio collection unit is the place of 27 °, can determine that so the first angle is 27 °; Calculate to obtain the first sound source perpendicular bisector angle between the first audio collection unit of electronic equipment and the second audio collection unit and be the place of 30 °, can determine that so the first angle is 30 °.

(2), based on described the first angle, determine that first sound sound data corresponding to described the first sound source is that described plan gathers voice data or described noise sound data.

In step (1), obtained the first angle, below, based on the first angle, just can determine first sound sound data is to intend having gathered voice data or noise sound data, thereby the voice data of subsequent acquisition is processed, to improve recording quality.

In the embodiment of the present application, by the first angle, judge that first sound sound data is to intend gathering voice data or noise sound data, is specifically as follows:

1) judge whether described the first angle is less than or equal to the first predetermined angle, obtain the first judged result;

2), when described the first judged result shows that described the first angle is less than or equal to described the first predetermined angle, determine that described first sound sound data is that described plan gathers voice data;

Or when described the first judged result shows that described the first angle is greater than described the first predetermined angle, determine that described first sound sound data is described noise sound data.

By the first angle, determine that first sound sound data is to intend gathering voice data or noise sound data, specifically, judges the size of the first angle and the first predetermined angle exactly.

Wherein, the first predetermined angle can be producer at before sales through the preferably angle that repeatedly test obtains, arbitrarily angled as in 30～35 °, and be built in electronic equipment, user can not arbitrarily change; Also can be user according to liking or being accustomed to selecting the selection in electronic equipment to arrange, as electronic equipment provides 3 options to user, be respectively 30 °, 32 ° and 35 °, user selects by button or touch-control.Suppose that the first predetermined angle is 30 °, the first angle is 31.4 °, and the first angle is greater than the first predetermined angle so, and first the determination result is NO; The first predetermined angle is 30 °, and the first angle is 30 °, and the first angle equals the first predetermined angle so, first judgment result is that and is; The first predetermined angle is 30 °, and the first angle is 15 °, and the first angle is less than the first predetermined angle so, first judgment result is that and is.

Judgment result is that while being when first, show that the first angle is less than or equal to the first predetermined angle, the angle of the first sound and electronic equipment is less, can determine that so first sound sound data is for intending gathering voice data; When first when the determination result is NO, show that the first angle is greater than the first predetermined angle, the angle of the first sound and electronic equipment is larger, can determine that so first sound sound data is noise sound data.

Below, execution step S2.
