I have posted something in this thread already. You can download it from megaupload here: www.megaupload.com...
The sound was quite different to what I have heard before, but probably a bit more like some of the sounds I've heard other people post on youtube. I
have tried to analyse the new sound, but without knowing what I'm looking for, and without any real knowledge of sound and frequency analysis, I'm
blundering about a bit.
I took a short, clean-ish sample from towards the end of the file, and I have started to look at it. I posted some pictures earlier on in this thread
which showed some peaks at 200, 300, 600, 800 and 1000Hz (and also at around 2000Hz). This seems odd to me, but it probably says more about my
frequency analysis skills.
Anyway, I decided to have a look at the amplitude of the signal during this same 0.6 second section:
It looks quite regular to me. I know this sample really isn't big enough, but I thought I would try to determine the 'wavelength'. I recorded the
bottom of the wave at 0.08, 0.22, 0.355, and 0.485 seconds, giving wavelengths of 0.14, 0.135, and 0.13 seconds. Lets call it 0.135 seconds. That's
7.4Hz - not a million miles away from 7.8 Hz - the fundamental Schumann resonance
I hope there's someone out there who understands this better than I do. Is any of this analysis meaningful?
