alt Hacker NewsInteresting 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.

Yes, it's called impulse response, used to capture convolutional reverbs, to model "real" sound stages like a large hall or what have you
Yup, that would be an impulse response, and if the room acts as a linear (and time-invariant) filter, then you can easily figure all that out, and the write-up is basically about testing if it's so and how good the reconstruction is.
And there is a way to toggle it: the icon which is orange can be tapped on and off, and you can adjust the "bass" which is built in with the ring around it. Also, it's likely to have no effect on voice, more complex arrangements will have an audible difference.
There is similarly an example on Wikipedia too, which got me interested: https://en.wikipedia.org/wiki/File:BinauralPaper.ogg.
