The early research on auditory scene analysis (ASA) - the subject of my talk at the corresponding IEEE workshop in 1995 - has been followed by many exciting studies that have opened up new directions of research. A number of them will be discussed under the following headings: (1) What is the role of attention in ASA? (2) What have we learned by using evoked potentials to study ASA?

(5) How is "binding" carried out in the brain?
