In some recordings with music and voice, the voice is mixed to the
center and the music is panned from the left to the right.
If you have a recording like this, it would be possible to use an 
arrangement of OpAmps to add and subtract the left and right channels 
from each other to give a music only, music and voice, and voice only.
This is not perfect, there will always be something of the other 
signal feeding through.  There is nothing "magic" that can be done and 
it depends totally on the recording.
A few companies have sold circuits to do this but these have always 
been to take out the voice and leave the music ( so that you can sing 
along )
