Example Embodiment

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0047] In order to solve the technical problem that audio recording based on dual microphones set on the terminal in the traditional technology cannot adapt to different usage scenarios, the sound reception effect is poor. In this embodiment, a recording method based on dual microphones is proposed. The implementation of the method can rely on a computer program, which can run on a computer system based on the Von Neumann system, and the ...

Abstract

The embodiment of the invention discloses a recording method based on double microphones, and a terminal. The method is applied to the terminal equipped with the double microphones. A first microphone is arranged at the bottom of the terminal. A second microphone is arranged on the top of the terminal. The method comprises the steps of detecting a screen state of the terminal; collecting first audio data and second audio data by use of the first microphone and the second microphone at the same time when the screen state of the terminal is a transverse screen; and superimposing the first audio data and the second audio data, thereby synthesizing the recorded audios. According to the method and the terminal, the recording quality of the device with the double microphones can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a recording method and terminal based on dual microphones. Background technique [0002] With the development of terminal technology, most of the microphones on terminal devices such as smartphones adopt a dual-microphone design or more microphone designs. For example, in figure 1 In the shown application scenario, two microphones are set on the terminal, namely a first microphone M1 set at the bottom of the terminal and a second microphone M2 set at the top of the terminal. [0003] Generally speaking, during a call, the two microphones are subtracted, which can better ensure that the two microphones point in the direction (see figure 1 , the dual microphone pointing direction and the vertical direction of the dual microphone pointing direction) to collect the human voice effect, while shielding the sound reception effect from the side. During the recording process, ...
