resultant tones

No SAT, but I get a 349hz, and a 440hz, give or take 0.03hz depending on
where the FFT is done in the sample(s). The 440 tone seems to have a little
something else just on the high side of it that blends into the 440 peak
about 1.5hz above it. I'm not sure what it is or just how to read it yet,
but I'll see if I can figure it out.
