It's not really digital quantisation that's the problem, but everything else that happens during mixing - which is a much more complicated process, especially for pop/rock/electronic etc., than just "sum all the signals together".

There's a bunch of other stuff that happens during and after summing which makes it much harder to reliably 100% reverse that process.

I didn't mean to say that quantization was the problem, just that you're basically trying to pick apart a "pixel" (to continue my image-based analogy) that is a composite of multiple sounds (or partially-transparent image layers).

I was sincere when I said:

I was hoping someone would come along and say it is, in fact, possible. :)
