Wierd vocal artifact merge with rhythm guitar!

Audacity 2.0.5

When making the beatles song She Loves You into stereo i have come across this.

On the right i have the rhythm guitar but some vocals are merged with it. Thats what i get for using noise removal. i dont want to use noise removal again to remove it because it will take down the quality of the rhythm guitar and create more artifacts. Is there anything I can do ?

So you’re trying to separate out different sounds from the stereo mix so that you can pan them to different positions in the stereo field?

Separating individual sounds from a stereo mix is at best difficult to do, and at worst is impossible.

Have you tried faking stereo? It can often sound remarkably effective and is very easy to do. There is a plug-in available here: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Pseudo-Stereo

when they mixed this song to mono, along with 3 other songs, they scrapped the tapes because in 1963 mono was more popular. no stereo was ever created. people have done duophonic mixes of this song before and it doesnt turn out too well. the only way to make a good stereo is to put each instrument at a different channel.

So you want to separate out the instruments from the mono mix?
Please let us know if you find a way to do that. The only way that I can think of that might work is to spend many many hours manually teasing apart the spectrum using Melodyne (expensive software by Celemony).
