Glenn,

That's the art of field recording. Full stop. :-)

When I got paid for doing it, my job description was virtually "minimising=

noise".

First train your ears to hear noise. They are very good at ignoring noise.=

When I had trainees. I started out by asking them to list everything they
could hear. Top marks if they included tinnitus. :-)

Cup your hands behind your ears and listen all round and up and down.

Try baffling the unwanted sound. Try putting the mics on the ground or
behind a vehicle or buiding or anything that can form a baffle including
your body if you can breathe quietly.

I've got a grain mill about a mile away and the wind can bring in a whine a=
t
a fixed pitch. I sometimes use a mild narrow notch filter in the free
Audacity editor to reduce it provided it doesn't interfere with the natural=

sounds I want.

Oh yes you can. :-) If not, wave a directional mic around and listen out at=

a higher level.

More directional mics are more complex to use in stereo, but starting with =
a
cardiod, you can face this away from a noise source rather than directly at=

the scene you want to record. For instance if you have a low reflective
ground texture and a pair of cardioids, try tilting them downwards to
minimise plane noise.

Bear in mind than many stereo mic rigs are also sensitive to sounds/noise
above, below and to the rear.

If all else fails, read the arguments on this list on how best to get good=

natural sounds.
