Separate voice from song?

Hello. I have Audacity 2.1.0. I just downloaded it. I found the “Vocal Remover” tool under effects which removes the vocals from songs and leaves the song itself, but I can’t find any effect to do the opposite, remove the song and leave the vocals. How do I do this? Or maybe separating the vocals from the song and having them in two files would work; like keeping the vocals separate from the song instead of just deleting the vocals like “Vocal Remover” does.

In Audacity 2.2.0 available here:

There is Effect > Vocal Reduction and Isolation.

Try it before you tell your client you can do this. There’s a long list of ways this can fail. It’s usually best if you go in assuming it’s not going to work.

For example, if you have a mono show (one blue wave), that’s the end of the story. It doesn’t work at all in Mono.

A cousin to this is having a stereo show (two blue waves) but the waves are the same. That doesn’t work, either.

And etc.
