Abstract
Implementations disclose filtering wind noises in video content. A method includes receiving video content comprising an audio component and a video component, detecting, by a processing device, occurrence of a wind noise artifact in a segment of the audio component, identifying an intensity of the wind noise artifact, wherein the intensity is based on a signal-to-noise ratio of the wind noise artifact, selecting, by the processing device, a wind noise replacement operation based on the identified intensity of the wind noise artifact, and applying, by the processing device, the selected wind noise replacement operation to the segment of the audio component to remove the wind noise artifact from the segment.
