So today I sat down and implemented the algorithm. I was unsurprised but
rather disappointed to discover that IT DOESN'T WORK.
I tried it on an artificially simplified 1D example. Invented a fake
signal, convolved it with a simple filter kernel, and then let the
algorithm try to recover the original signal. The end result bore
absolutely no resemblance to the original.
It's possible that 44 samples just isn't enough for a reasonably unique
solution to exist. More likely I've implemented the DFT wrong or
something...
