So, there I was contemplating the easiest way to decode (as a non-keyer) the single-frequency pattern, reminiscent of Morse Code, hiding from time to time in the background noise of the Evanescence song My Immortal. (Yeah yeah, formally admitting that I listen to that stuff.) As an afterthought while thinking of the changes I'd need to make to my already-existing
Matlab Fourier Slicer (R)(tm)(c) for semi-automated decoding, I Googled to see if maybe some equally obsessive sap had already done the work for me.
Aww, le disappoint. When/if the GAS tank* refills, I might apply the
slicer to looking for
patterns in the noise of some industrial stuff. (Although in all reality, this easily exceeds the tank's maximum capacity.)
* the notional tank that buffers my Give-A-Shit reserve for a rainy day.
