The present embodiment can be applied to equally and utilize this electronic equipment to carry out voice call, or in the scene of voice recording.
In the present embodiment, when determining the relative position relation of user and this electronic equipment, according to the angular relationship information in this relative position relation, adjust the sound collection direction of sound collection unit, and then make sound collection unit can collect voice signal more accurately, and the noise signal that sound collection unit is collected reduces, thus improve voice collecting quality.Like this, again according to the sound generation source of this voice signal and the first distance of this sound collection unit, after have adjusted the signal intensity compensating parameter of the voice signal that this voice signal collects in this sound collection unit, after adjusting according to the intensity of this signal intensity compensating parameter to the voice signal in voice signal, thus advantageously in the quality improving the voice signal in the voice signal after adjusting, and then the quality of the voice signal of raising voice call quality or recording.
The effect of voice quality is gathered in order to sound collection unit can be improved further, in the present embodiment according to the angular relationship of this user and this electronic equipment, while the sound collection direction of this sound collection unit is adjusted, can also according to this angular relationship, the sound collection width of adjustment sound collection unit, with the noise signal outside sound collection width described in filtering.The concrete width that can adjust the beam forming of multiple sound collection subelement in sound collection unit, and then while making the collection direction of sound collection unit point to the sound generation source of this voice signal, the width making this sound collection unit gather sound reduces, thus the noise signal that sound collection unit is gathered outside width is not collected.
For the ease of understanding the solution of the present invention, see Fig. 3, show the schematic flow sheet of a kind of another embodiment of audio signal processing method of the present invention, the method of the present embodiment can be applied to equally arbitrarily can collected sound signal, and can carry out in the electronic equipment of respective handling to voice signal, if this electronic equipment can be mobile phone, pad, notebook computer, MP3 or MP5 etc., the electronic equipment of the present embodiment has sound collection unit, it is example that the method electronic equipment of the present embodiment is in call mode, and the method for the present embodiment comprises:

This opposite end electronic equipment, for set up voice call with this electronic equipment, carries out the electronic equipment that speech data is mutual.
Wherein, this user refers to the local user of this electronic equipment, also can be understood as this electronic equipment user.
Step 302: according to the angular relationship of this user and this electronic equipment, the sound generation source of this voice signal is pointed in the sound collection direction of adjustment sound collection unit, and adjust the sound collection width of sound collection unit, with the noise signal outside this sound collection width of filtering.
Because the angular relationship of this user and this electronic equipment is the sound generation source of voice signal to be collected and the angular relationship of this electronic equipment, in the process of voice call, by this angular relationship, the collection direction of sound collection unit is adjusted with collection width, make the noise signal outside this sound collection direction and sound collection width not collected, thus decrease the collection of noise signal, and then improve the quality of the voice signal collected.
Step 303: by the distance of this user and this electronic equipment, be defined as the sound generation source of voice signal to be collected and the first distance of this electronic equipment.
Step 304: according to this first distance, adjusts the signal intensity compensating parameter in the voice signal that this voice signal collects in sound collection unit.
Step 305: the intensity adjusting this voice signal according to this signal intensity compensating parameter, and the voice signal after adjustment is sent to opposite end electronic equipment.
Optionally, this process can be utilize automatic growth control principle to adjust in the process of the signal intensity of other voice signals that voice signal sound collecting unit collects, according to this first distance, adjust described voice signal gain compensation value in automatic gain control, thus when utilizing automatic growth control to adjust this voice signal, according to this gain compensation value, this voice signal is amplified, make the voice signal in the voice signal exported and noise signal to reach balance, and the intensity of voice signal is larger.
By the method for the present embodiment, the noise collected in voice signal can be made to believe relatively less, simultaneously according to the sound generation source of voice signal and the first distance of electronic equipment, determine the signal intensity compensating parameter of this voice signal in voice signal adjustment process, and then after can making to amplify according to the intensity of this signal intensity compensating parameter to voice signal, voice signal is better in the sharpness of voice signal.
