Auditory scene analysis segregates sound first and forms percepts later

Evidence

Auditory Scene Analysis (ASA) introduced the principle of a two-stage process in the auditory processing of complex auditory scenes with competing sources (Bregman 1990 ). A first stage would involve segmenting the scene into auditory elements, which would be segregated or grouped in respect to their common source, either by bottom-up innate primitives or by learnt top-down schemas. Decision and formation of a final percept would be done at a second later stage. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5137
