Hi Steve!
Thanks for pointing out this plug-in. It's really handy. However it
doesn't do for me what I'm after in this case. Sure there isn't really a
centre channel, but isn't it possible to filter what is perceived to be
the centre and simply lower the volume, leaving the sides in tact?

Cheers, Robbie

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:
