Removing soundtrack

hello im bob and im working on a project to copy a dvd and remove the soundtrack but leave the dialogue. I can only rip the soundtrack to mp3 but not remove from the dvd. Can anyone help me with a solution to my problem please thanks. Ive not done this before but my email address is

If it’s 5.1 soundtrack you may be able to minimize the music by de-multiplexing the soundtrack, importing it into a multi channel audio editor like Audacity and saving just the center channel. That’s where most of the dialog will be, but there’s still likely to be traces of the music and sound effects. I believe Audacity now imports AC3 (DolBy Digital) directly.

PS: AVI DeMux can probably de-mux and save the AC3 audio track for you.
