As requested earlier.
The checks are pretty basic, but comparing FFTs of different sizes
proved difficult (I tried doing some linear filtering to bring FFTs
to the same size, but the value changes are so sudden I'd need to
smooth a lot to avoid false negatives, which would make the test
be very prone to false positives. There may be techniques for doing
this kind of thing, but I'm FFT ignorant so comments welcome).
