I am having trouble even figuring out where to begin in analyzing
infra-sound. Such as the UFO post, thunder post, or even a simple
bird such as my 200kb Grouse recording at
http://home.comcast.net/~richpeet/0298.wav
The spectral displays I have made with Cooledit seem to fall apart in
determination of very low frequency.
I also don't understand how waves work at low freqs. ie question 1.
1. If a wave length of 1/2 cycle audio is 2,260 feet long, can a wave
at the frequency be detected in a short burst such as this grouse?
2. How does one determine how low this bird goes?
3. How does one determine how low my recorder goes?
