I have a really cool video, but I don’t like the music. There are also people talking over the music. I want to add my own music but keep the people’s voices.
How would I do this?
If you add the FFMpeg software to Audacity, it will open up many videos directly—or at least the audio part of the video.
Scroll down to the additional software.

Then you can try Audacity Effect > Vocal Removal and Isolation.

And then you get stuck. Audacity has no way to put the new sound track back into the video. You need a video editor program.
