Abstract

The invention discloses a recording method and a recording device of electronic equipment, belongs to the technical field of communication, and can solve the problem of improving the recording quality. The electronic equipment comprises M microphones, each microphone is connected with a first voice path and a second voice path, and the scheme comprises the following steps: acquiring a shooting focal length of a camera in a video shooting state; if the shooting focal length is changed from the initial focal length to the target focal length, determining a target gain according to the initial focal length, the target focal length and the initial gain, and adjusting the gain of a second voice path connected with the ith microphone to the target gain, the initial gain being the gain of a firstvoice path connected with the ith microphone; performing signal enhancement processing on the voice signal output by the first voice path connected with the ith microphone and the voice signal outputby the second voice path to obtain an ith voice enhancement signal; and performing signal fusion processing on the M voice enhancement signals to obtain a first recording signal.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a recording method and a recording device for electronic equipment. Background technique [0002] With the rapid development of communication technology, most mobile terminals have a recording function. For example, a user can use a mobile terminal to shoot a short video including voice. [0003] Currently, when the user is in different environments, the distance between the sound source and the mobile terminal usually changes. As the distance between the sound source and the mobile terminal gradually increases, the sound recorded by the mobile terminal will gradually decrease, which may cause the user to be unable to hear the sound clearly; and as the distance between the sound source and the mobile terminal gradually decreases, the sound recorded by the mobile terminal will gradually decrease. Gradually increases, resulting in possible crackling. Therefore...
