I've been wondering about how to recreate this effect for quite a while now. It's that sort of artificial-background-vocal effect you here in a lot of pop songs.
From what I can tell, it involves some sort of double-tracking and stereo-field expansion, but that tends to leave things sounding really hollow and metallic. Does anyone know of a way to give the vocals a little more clarity and solidity while still having a strong chorus effect? I'm sure it's all fairly complicated but there must be some basic trick to it.
I could be missing what you are looking to create, but it sounds like the vocal is just doubled meaning the vocalist just came back and sang with the original vocal ... I have done things where I have had a bit of verb on the main vocal and took dry copies and panned one left 70 and right 70, on these vocals I added a chorus effect and mixed them in 2 to 3 db lower than the original vocal which gave me a very similar effect of what you are looking to create ... You may have to experiment with the type of chorusing you want, I believe I used the ACOUSTIC DUET setting in the delay effects menu ......... WILLIE
