Back in the 80s and 90s, at lot of us investigated auditory 
correlograms as a representation for sound separation and 
classification.  Since I've been away from the field for a decade, 
with the exception of monitoring this list a bit, I'd like to know if 
anyone is still actively persuing this approach.  And if not, what 
are the current hot alternative representations that try to connect 
what's known of the auditory system to the functions of sound 
separation and classification?
