The article talks about the white noise resonating with the signal but not the noise. I'm trying to picture white noise as a summation of all frequencies, but I've never thought about the phase of the components. If two signals of the same frequency are in phase then they resonate, but if they are out of phase they cancel each other out. What does the phase of the components look like in white noise?
After that, filter out unimportant frequencies and return the volume to normal.
The important data isn't the volume necessarily, but the specific frequency and tempo.
The article points out that with too much noise, this does not work.
