Abstract

The invention discloses a directed recording control method and device of a mobile terminal. The method comprises that when a recording direction selection event is found via monitoring, recording direction information input by a user is obtained; the recording direction is determined according to the recording direction information; and according to the determined recording direction, at least three microphones of the mobile terminal are controlled to carry out recording, and a recording file is generated. According to the technical scheme of the invention, when the position of a target sound source changes or the target sound source changes, the user can input the recording direction information of the expected recording direction in the mobile phone needless of changing the position or orientation of the mobile terminal, and directed recording is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of recording, and in particular to a method and device for controlling directional recording of a mobile terminal. Background technique [0002] In order to meet the recording needs of users in life and work, most mobile terminals, such as mobile phones, tablet computers, music players and professional recording pens, have recording functions. [0003] When the user uses the recording function of the mobile terminal, there are often voices of multiple people speaking and various environmental noises in the recording environment, so for the microphone used to realize the recording function, there are multiple sound sources around it, and the microphone will The sounds of these sound sources are all recorded to form recording files. However, what the user is interested in is often only the sound of the sound source in one direction. When listening to a recording file containing the s...
