With a normal stereo recording the "centre section" does not really
exist. Conventional stereo uses just left and right channels.
Sounds that are in the centre of the stereo field are an illusion that
is created by having identical content in both the left and the right
channels.
Vocal removal can be achieved by inverting (turning upside down) the
waveform of one channel and adding (mixing) it with the other channel.
Content that was previously identical in both channels becomes
"opposite", and so when added together the inverted data cancels out
the original version.
The act of "adding" the left and (inverted) right channels together,
by necessity, produces one output channel, which is then duplicated
into both channels.
There is a plug-in called "Channel Mixer" which allows other types of
manipulation of left and right audio channels. The Channel Mixer
plug-in is available here:
