Dan,
No physics perhaps, but we often need to describe a stereo illusion
and in particular how well it resolves. That's what the sonel
provides.

Perhaps it is pushing a simple concept too far, but there is often
pincushion or barrel distortion between the original sound object and
the recorded sound image and unless we can describe this in an
elemental way, how else can it be quantified?

How does he describe the individual placings in the stereo image?
