Hi -
I don't know of any work in this area using sc - I take it that's what
you're asking for?
BSS is a difficult task and particularly to do it in real-time is
extremely difficult, since it would have to be very efficient and also
work without knowledge of the entire signal. The vast majority of BSS
algorithms are non-real-time and so sc wouldn't be suited to them.
There are some real-time BSS implementations (e.g. one Japanese
university has commercially produced a source-separating microphone
[Hiroshi Saruwatari's group]), but I don't know enough to say whether
they could be implemented in a system like sc.
