Thanks yes, this is totally correct -- the FFT uses a Tukey window, which should be able to match the main lobe. I got some other feedback that perceptual training tasks have a very long tail, so it's possible that the network will learn better if I run it for a few hours (I only ran it for about 10 minutes.) I'll give it a shot (and edit the post.)
