Ok i will try too make this clear as possible. you know how at the end of a tv show that the tv station talks a few secs well i would like too drop out that forground audio and bring up the background audio. dose any budy know a program or a filter for virtualdub?

whoo, tough one

you could try adobe auditions centerchannelextarctor to remove center/mono information, the stereo parts of the music would remain

the easiest part would be to find a complete version of the music and replace the useless part in the cap

well dose adobe auditions drop out the forground and bring up the background?

no, that is not possible with any method i can imagine
it'll only remove the mono/center part
not worth it IMO

the problem is this:
1st: you need a somewhat mathematical description of what you call foreground, because computers are dumb and only understand numbers
2nd: if you make somethign quiter and put somethign lauder over it you destroy part of it, and the technology to recreatesuch losses isn't there (yet) AFAIK

so as i said, it's best to get some clean version of the ending-music and replace the "damaged" ones

Well, someone once compared the process of restoring distinct audio tracks (which you'd need here) from a mixdown with restoring a fully working cow from a pot of beef stew - it just can't be done.

np: Francesco Sansalone - Spleen (Texhnolyze OST Music, Only Music, But Music)

yeah it can be done it's a just a matter of time before some1 devels software too bring up the background and drop out the forground it the man or woman that is taking in the forground that's what need's too be droped out

you can recreate it to a certain extend, sure, BUT:
it's a lot of work, much more than it's worth
and it'll never ever be 100%

let's take this analogy:
you have a painting, you spray a graphity over it and take a pic of that with your digicam
now on that digital picture try to remove the graphity and get back the painting (including the parts that where totally covered by the graphity)
see? you can't the information isn't there
you can interplorate and extrapolate stuff, but that'll not be your original painting, just some stuff fitting in

the main problem in your case is again:
a progammer needs a definition of "foreground" and "background" he can put into math
got one?
