I see that the question of making an FAQ for this group has come up before,
but so far there is none. As a new member with lots of questions, I'll
throw in my vote for one. Has anyone been collecting questions for making
an FAQ?
I have a question. My particular interest is in recording various natural
forms of energy that are NOT in sound form, and converting them to sound.
Are there any web sites you would suggest I look at? I've seen Stephen P.
McGreevy's atmosphere ELF-VLF web site - that's the kind of stuff that
interests me. But there are so many other possibilities. For example,
converting earthquake seismic data into sound. Or sensitive micro-seismic
data of an insect walking. Or atmospheric pressure variations (which are
essentially VLF sound) sped up to audible range. Cosmic rays? Earth's
natural electric field? Sound of ice freezing? CO2 (or other gases)
concentration in the air near a tree, measured over months, converted to
sound, sped up? Sound of a spider spinning a web?
Anything that changes with time is a possibility. But it wouldn't even hav=
e
to be that. You could record the height of the mountain range on the
horizon and convert that to a sound wave, mapping horizontal distance onto
time.
I thought it would be interesting to build an ultrasound receiver with a bo=
x
to bring the sound down to audible range, then walk around the environment
and find out what kinds of ultrasounds are out there.
Is there a web site containing a complete list of links to nature-recording
web sites with sound files?
