Abstract

A method for suppressing the wind noise of a microphone and an electronic device are provided. The method for suppressing the wind noise of the microphone comprises the following steps: receiving an audio signal; obtaining a frequency spectrum and a power spectrum of the received audio signal; determining a wind noise power spectrum of the audio signal based on the power spectrum; determining a wind noise suppression gain based on the wind noise power spectrum and the power spectrum; correcting the frequency spectrum according to the determined wind noise suppression gain; and converting the corrected frequency spectrum to a time domain to obtain a corrected audio signal.

Description

technical field [0001] Some example embodiments relate to the field of audio processing. More specifically, it relates to a method and / or electronic device for suppressing wind noise of a microphone. Background technique [0002] With the development of technology, portable terminals are widely used. Many portable terminals support the audio capture function. The portable terminal can collect audio signals through the microphone, and then process the collected audio signals. However, when the audio signal is collected through the microphone, when there is wind in the external environment, the audio signal is sometimes inevitably affected by wind noise, which affects the quality of the collected audio signal. [0003] Therefore, a technique for suppressing or reducing wind noise of a microphone is being pursued. Contents of the invention [0004] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the De...
