1. To remove the original sound but keep the background music, you first need to separate the original sound track from the dubbing video, then add the background music file to the video, and finally delete the original sound track from the video. That’s it.

2. Open Douyin and click the plus sign at the bottom. Click "Album" in the lower right corner to import video material from the album. After importing the video, click Next in the upper right corner. Click "Select Music" at the top. In the bottom options, uncheck "Video Original Sound" and the video original sound will be removed.

3. The prerequisite for removing the dialogue and retaining the background music is that the dialogue and background music are on two audio tracks. To remove one of the two audio tracks, you can use format conversion software, such as Format Factory.

4. First open the running software, click "New Project", and then click "OK" on the interface that pops up later. Double-click the blank space in the Project: Unnamed panel or click the right-click menu and click "Import". Select the video whose vocals you want to mute in the computer directory and click "Open".

5. The method of eliminating vocals and retaining background music is as follows: First open the GlodWave software, click on the file, and open the music we want to edit.
