- If there is a howling wind, then capture it on your tape! What you have
- to avoid is the microphone diaphragm being flapped around by the wind.
- Foam on its own is not realy good enough. I used to use a foam windshield
- surrounded by a very thin cotton handerkerchief, but you can also use
- nylon stockings or tights. That worked reasonably well even when hung
- out of train windows.
-
- If you can afford it get a professional windshield with what I call a
- "shaggy dog" cover. Various sizes are available. These have a much thinner
- layer of foam and you don't loose so much 'top'.
-
- Another point to bear in mind is that omnidirectional (pressure) microphones
- are much less susceptible to wind than cardioids, and figure-of-8 (velocity)
- mics are the worst. Even if you are recording in stereo it is worthwhile
- considering using omnis in high winds.
-
- I would also suggest that you place your mics a lot further back from the
- tracks, particularly if you are recording in stereo. This will resuce the
- air disturbance from the train itself, and will also reduce the dynamic
- range of the recording so you can turn the recording level up and get a
- better recording of the train approaching. In stereo there will be less
- of a tendency to get a hole in the middle of the stereo image.
-
- Good luck!
