Abstract: This work is an attempt to model auditory object perception as the outcome of modulation analysis along the three innate dimensions of any sound out there: "what" (~spectral content), "when" (~fluctuation in the time domain), and "where" (~location). The novelty of this model is that it merges spatial modulation (i.e., resolution of sounds coming from various simultaneous sources in our acoustic environment) and the spectro-temporal modulation analysis already used by many computational neuroscientists (e.g., Shamma, Theunissen, Elhilali, etc.) to represent and explain the analysis done at a central (cortical) stage following spectral-temporal-spatial analysis at the periphery. The model puts a novel twist on the perceptual separation of simultaneous sounds, or the "cocktail-party effect," or the perception of 24-channel soundscapes.
