Hello everyone,

Thank you all very much indeed for your helpful replies. The naturerecordis=
ts group is the friendliest and most supportive of all internet resources f=
or field recordists.

It's been a real pleasure listening to those excellent recordings from Aust=
ralia, Iceland, the United States and elsewhere.

The points which stand out as particularly relevant are:

* The Rode NT1A is remarkably good for what it costs. However, high wind sp=
eeds and moisture or humidity levels can pose problems. The Scottish Highla=
nds have plenty of both, yet the Icelandic recordings come from an equally,=
 if not more challenging environment and they show how patient and skillful=
 recordists can overcome them.

* The Audio Technica 4022 looks very promising as a more robust workhorse w=
ith wider application. Tony/Binaural Brisbane - thanks very much for linkin=
g to Vicki Powys's series of comparisons. It was good to see how well the A=
T 4022 did alongside much more expensive mics like the MKH 8020. But this i=
sn't a total surprise - I own an AT BP4025 and would recommend it to anyone=
 who wants a go-anywhere single-point stereo mic.

Someone asked what environments are so quiet as to require mics with extrem=
ely low self-noise levels.

About ten years ago I began hiking and hill-walking in the Cairngorms and e=
lsewhere in the Scottish Highlands, equipped with a tent and a supply of pa=
sta and instant porridge.

It was in mid-March and daytime temperatures were just above zero centigrad=
e. I was heading eastwards from Corrour towards Ben Alder and Loch Ericht a=
long a small valley. It was a tiring journey and eventually I climbed out o=
f the valley onto a path skirting the western flank of Ben Alder. What a re=
lief to walk on a path again, rather than hopping from peat hag to peat hag=
, or sinking into boggy patches of moss!

I sat down on a small boulder to get my breath back. The Alder Burn chatter=
ed a few dozen yards away. Geese honked briefly in the distance on Loch Eri=
cht, then stopped. My breathing slowed and without the sound of my backpack=
 creaking my ears began to adjust.

I became aware of what sounded like a jet flying high up. Even here it seem=
ed you couldn't get away from them. Minutes went by and it didn't grow any =
weaker - faint yet somehow monumental in its changeless and indifferent sou=
nd. Then I realised it must be the sound of the wind, of great masses of ai=
r rushing and spilling over the top of the mountain. It was a moving moment=
 and one which I think of from time to time, here in the city with all its =
meaningless racket.

Best wishes
