Still very much a God's-ear view.  For realistic
interaural delays, you'd want to increase the
mic distance over human ear-to-ear gap by the
same factor as the time speedup.

So everything shifted 4 octaves up ... birds might still be
audible to some, but not me.

There was definitely some phase wierdness going on there,
but I wouldn't call the result stereo.  I wonder how much of it
could be accounted for by pathlength perturbations due
to wind turbulance, especially in the lowest couple of
hundred feet of atmosphere where there was distinctly
different air over each mic?
