i don't think that's possible. imagine two similar instruments, one at
0° and the other at 180°. once recorded in mono, they will be fused
together irrevocably. you won't be able to separate them with the help
of any vector metadata.
Any microphone capable of separating two sound sources MUST be large in
terms of wavelengths (similar to the diffraction limit for telescopes)
The soundfield microphone cannot separate two or more sound sources at
_any_ frequency for this reason. This does not seem to worry the 'fanboys'.
