PPPS:
Phases are the ABC of audio engineering, everything that has to do with
music, has to do with time. Everything is time related, every EQ, just
everything. There's no math that is able to separate channels by phases,
assumed the frequencies are all recorded just by audible frequencies and
not transformed to higher frequencies, by theory transposing to
inaudible and back to audible frequencies could work. Practical, hm?!
There already is no perfect backwards compatibility from 2 channels to
one channel regarding to timing issues, e.g. the +/- 180° thingy. It's
completely idiotic to add a third channel by what ever time shift to 2
channels and then to decode this nonsense.
Unbelievable that this is a serious discussion :(. During the decoding
there will be overlapping between the clean stereo signal and the third
channel. Take a pencil and draw 3 sinuses to a paper by your imagination
and than think about adding the third sinus to the two other sinus. Some
kind of encoding and decoding, just by an imaginary picture in your
mind.
I'm quit now.
