But, if you take the photo from behind the mic looking in the direction of
the principal axis of the sonic image (if there is one) - so, maybe centre
stage for DWMM - you get both the atmosphere and the better chance of
eliminating error by actually including the mic.

Great idea, the only problem being the presence of un-synced digital
electronics near ultra sensitive analogue electronics in the microphone
which would necessitate some very, very careful design to avoid
interference. Might be better to develop a smartphone app that took a photo
of the mic,
Make a mic mount with an iPhone holder, and you can use compass and gyroscopes
as well as GPS.
That way you have location data and mic orientation data captured and can
auto-transform the signal based on that.
Just be sure to turn off the mobile phone radio, because GSM signaling causes

The usefulness may not be obvious. One application would be
forensics. If someone is trying to determine direction of a sound
source after post processing, this could be useful. But my initial
thoughts were
Very interesting idea Eric. There are also sorts of insects, birds etc
that navigate by the Earths magnetic field, the moon (thats why moths
fly round a candle etc) . To navigate by a sound though it would have
to be a fixed point or a sound that stayed in the same place pretty
consistently for
another thing that might be really cool would be to have a time of day and
GPS location feed,
so then you'd know exactly where and when it was recorded - this might be
useful for conservation projects...
