Part 2 Replace Audio in YouTube Video with Your Own File

Once your video is uploaded, though you can add an audio or change the audio track through the YouTube editor, you cannot change it to an audio track from somewhere other than the YouTube Audio Library. That's to say, there is no way for you to replace audio in a YouTube video with your own file after uploading the video to YouTube.

To replace audio in YouTube video with your own file, the only workaround is to replace audio in the video before uploading it to YouTube. Then, you'll need a third-party YouTube video editor. Here, we strongly recommend FlexClip. It is a powerful online video editor that allows you to remove and change the audio to your own file in a video. It gives you many controls over the added audio track details. You can set up the start time and the end time of the audio track, you can trim the audio length to match the video length, you can tune the original video sound volume as well as the imported audio track volume. Almost all audio formats and video formats are well-supported.

Now, let’s learn how you can replace audio in a YouTube video with your own file with FlexClip.
