Abstract : When concurrent acoustic signals are produced from different sources, their evolution in the spectro-temporal domain is independent. Each signal may however contain short-term spectral events with a common modulation of amplitude across time. This comodulation may be helpful for building auditory streams. When the information that is processed by two spectral channels share a common amplitude modulation, the auditory system may group these events together into a single auditory object whereas when their modulations differ, they would be parsed into different representations.

Keywords : figure-ground separation Speech perception Enveloppe modulations Fine spectral structure figure-ground separation.
