Interesting article. I don't know much about sound processing but it reminded me of the Fruity Convolver in FL Studio, which can somehow apply the characteristics of one sound (an impulse?) to your audio stream. It has interesting effects built in, reverbs recorded in different unusual spaces, as well as guitar amps.

I would have liked to compare the audio clip from the beginning of the article, at the end too! Instead I had to record my own voice. And there doesn't seem to be a way to toggle the effect on and off? So it's a bit hard to get a sense of what it actually does.

This also reminds me of this cool mp3 from the 2000s — maybe it's on YouTube these days — called virtual barbershop, which was recorded with binaural microphones.
