We have two ears, and two output channels to fool with on the Amiga.
Each of the stereo channels has two real hardware channels feeding
into it.  If I hack the audiotools to add the stereo support
that I need for a coming hack, I can send the same sound to
a left and right channel at the same time, one at a higher volume
and the other at a lower volume, moving the sound from left to
right as the volume is modified on both channels simultaneously.

Then, not only control the volume, but also control the phasing
between the two channels a little bit so as to create a distance
perception "somewhere out there in front of me to the left or the
right".

But what kind of controls must I apply to make the sound appear
to be "behind me"?????

Just thought someone else here might have a ready answer.  When
and if I manage any part of the above, it will become part of
the audiotools and made available to whomever wants it, prolly
through some public distribution channels near you.
