 The blind source separation (BSS) problem, also better known as the "cocktail party problem", is a well-known and challenging problem in mathematics and engineering. In this talk we discuss a novel  time-frequency technique for the BSS problem. We also discuss a related  problem in which foreground audio signal is mixed with strong background  noise, and present techniques for suppress the background noise.
