Separate background music from audio file

Hi everyone,

How can I separate the dialogue and background music in an audio file? I have a training course video where I would like to change the background music but Da Vinci Resolve 16 only shows me one audio track (both music and dialogue blended together) when I import the training course. I didn't make the training course so I don"t have the raw file. Please help.

Kind Regards,

Julia

You can't. The creator of the course would have to do it.

There should be 2 sounds separately. You cannot separate it from one file.
