Abstract

The embodiment of the invention provides a denoising method and a mobile terminal, relates to the technical field of communication, and aims to solve the problem that motor noise doped in a recorded audio file cannot be eliminated. The denoising method comprises the following steps: under the condition that a first target file contains noise data, obtaining a target feature fingerprint set of thefirst target file; under the condition that a first feature fingerprint set matched with the target feature fingerprint set is obtained from a database, obtaining a second target file corresponding tothe first feature fingerprint set; and updating the first target file according to the second target file, wherein the database is used for storing files without noise data. The denoising method in the embodiment of the invention is applied to the mobile terminal.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a noise removal method and a mobile terminal. Background technique [0002] At present, the telescopic and rotating cameras used in smart mobile terminals are gradually increasing, especially the rotating cameras, which can realize automatic follow-up shooting, directional recording and video recording and other functions within the rotation angle. and rotate. [0003] Among them, the stepper motor will generate steady-state noise during the working process, and the noise energy is concentrated at some fixed frequency points (such as 2400Hz, related to the control frequency). Usually, the frequency of this kind of noise is in the speech frequency band, which overlaps with the spectrum of effective speech, causing noise when the user uses the above-mentioned rotating camera to record and record, so that the recorded audio file is mixed with...
