Well, I did go onto the salt marsh yesterday to field test the
lightweight, head spaced barrier rig.  It was a bit of a mistake.  It
was late afternoon and a combine was harvesting wheat, maybe barley,
some two miles away.  It was also a peak time for aircraft en-route to
the London airports.  Consequently there was continuous background
noise of combine plus jets.  There was little bird activity. After 45
minutes I gave up and walked backwards and forwards in front of the
rig to, at least, test its ability to record something in stereo.  I
did not intend to post the results here as a field test.

However, after reading the following in Rob's post this morning

Hi Scott-
In addition to the fact that many natural events involve movement,
stereo imaging performance judgements based on trajectory and
momentum might be easier to make than those based on identifying
stationary "clock" positions. The closer the car or other moving
object comes to the mic array, the more depth imaging performance is
involved. There seem to be many qualities, including several
qualities of "motion" to appreciate in stereo imagining.

I decided it might be worthwhile posting the snippet with the
footsteps.  it is in the Files section with the name "footstepsb.mp3"

The combine is on the left, aircraft are overhead but left of centre.
 There are also some faint nature sounds -(better heard with
headphones) a curlew? green woodpecker and an insect buzzing around.
The footfalls on the dry marsh debris  could almost replicate clock
ticking (as referred to in Rob's extract above) as they progress from
right to left and back again.

For the record the 3032s were 1.5" from the front edge of the barrier.
 HiMD recording with mic volume set at 24.

Cheers
