I believe you are only pretending not to know about groups, Al. Perhaps you don't find the concept useful in your work? A group is a set of elements that is perceived as belonging together. In audition, these elements usually come from the same source, which is another property (besides temporal non-overlap) that distinguishes groups from streams. Perceptual grouping is as basic and ubiquitous a process as streaming, and there is a large literature on it. Grouping provides organization within streams. --Bruno Bruno H.
