It often happens that the audio track of your home video lacks quality: the background music is noisy, or there is unwanted sound. Thus you need to enhance the quality of the audio track to improve the overall quality of your video, and you can also reverse audio to make your video funnier.

It is so easy to edit an audio track with Filmora. This program will allow you to open a video file, edit its audio track, and save the result as a video file with the new, modified audio track. Filmora is a full-featured professional video editing and audio editing software for Windows and Mac computers. You can use the built-in editing tools to cut, copy, paste, or insert audio files, mute the audio in video, add your voiceover, or add a new audio track from the Audio Library. Follow this simple guideline below to edit the audio track of your video.

Step 2: Start editing the audio track

The second thing is to drag and drop the video or audio file into the tool’s timeline. After that, you can start editing the audio track of your video.

Separate audio from video

If you are editing a video with audio built-in, you can first separate the audio from the video. Wondershare Filmora enables you to detach audio from video. To do this, just move the cursor into the video to highlight it. Then right-click and choose Audio Detach. The audio file from your video will immediately appear in the music timeline. Since it is separated from the video, you can easily delete the audio track or cut and choose the proper section.
