my mistake i didn't realize spectrogram and spectrum were distinct objects.
>Also, it’s computationally intractable to individually train 2^N weights.
that's a good point - i'd forgotten for a moment (because i'm so used to cooley-tukey fft) that in principle getting the spectrum involves a matmul against the entire vector. which brings up a potentially interested question: can you get a DNN to simulate the cooley-tukey fft (stride permutations and all).
