How to Edit Sound in Video

Last Updated: April 8, 2021

This wikiHow teaches you how to change sounds in a video. You can adjust existing sounds as well as add new sounds, such as music or sound effects. Many phones, tablets, and computers come with apps that allow you to edit videos, but you might want to download a third-party app to give you more functionality.
