The alternative to having multiple virtual

speakers fed with the same signal is to spread

a single channel out.  You split the channel

into a range of frequencies, and then place

each frequency at a different position.  This

was a technique used on the old analogue

Ambisonics studio kit.
The same idea is used in the PS22 Stereo

Maker plug-in from Waves Audio although, in

this case, it is being used to spread a

single channel into stereo.  The screenshot on

Page 21 of their manual should give you the

idea, visit:

It should also be straightforward to extend the

technique to 3-D using an elliptical spiral.

Martin
