This is untrue, things like Fourier transforms can account for those variables.

I'd love to see a demonstration of this. (not of a FFT, but use of one to remove one signal from another)

They might have done this to extract instruments, and if you can extract one then maybe you can just subtract it from the main recording. https://www.sciencedaily.com/releases/2008/10/081030201607.h...

Identifying the fundamental pitches of notes in a chord is a far cry from subtracting them out of a recording.
