Okay, so
@jix got it first without spoiling it too much, and@datenwolf said it out loud. The answer is that it sounds exactly the same as a square wave, because it is a square wave, with every frequency component phase shifted by 90 degrees.Show this thread -
So take the Hilbert transform, or multiply every component of the (positive/real) FFT by i.

Why do I feel like it’s an inversion (pull up / down) of a sine wave?
