Wow, yeah you're right. I gave the feasibility analysis a more thorough read and it seems like they're exploiting the amplifier inside the mic itself to down-convert the frequency on portions of the signal. I don't fully understand what nonlinearity is being taken advantage of, but to as an acoustics layman this seems pretty impressive!
