How to remove vocals from 5.1 Audio

Hello i tried removing it with audacity but its not working can anyone help me with how to remove vocals from 5.1 audio i already extracted ac3 file and even i have them in 6 wav format but vocals and sound are mixed in center channel.

There’s probably no way to extract vocals from other sound that is mixed into the same channel.

Once Center is contaminated, you’re stuck. What’s supposed to happen is Center contains all or almost all the dialog and Front Left and Front Right contain the stereo show and everything except the dialog.

LFE is for earthquakes and thunder and the two rear channels are ambience and the first things to throw away when you mix down.
