Is there an audio separating program?

[asdfghqwer]

What I want is a program I can install that will let tone player's audio continue to play through the speakers, but send the audio of another program to the headphones.

Does this exist? Any suggestions of search terms or settings I can adjust?

I can't seem to find it, but I don't have the technical vocabulary to narrow it down.

This would work without any additional program, if you have TWO sound cards.
