Background
In order to meet the recording requirements of users in life and work, most mobile digital terminals have the recording function, such as mobile phones, tablets and the like. When a user uses the recording function of the mobile terminal, environmental noise often exists in the recording environment. Therefore, for the microphone for realizing the recording function of the user, a plurality of sound sources exist around the microphone, and the microphone can record the sound sources together to form recording during recording. However, the user is interested in the sound of the sound source with only one direction, which causes the recorded noise to affect the user identification. In order to make the total sound source of the recording file clearer, a user often needs to point a microphone in a mobile device terminal to the required sound source, and when the position of the sound source is changed continuously or the user changes the recording requirement of one sound source into the recording requirement of another sound source, the user needs to debug the mobile device manually to record continuously, which is inconvenient.
