Auditory Scene Analysis

Definition

Albert Bregman's psychological framework (1990) for how the human auditory system parses complex acoustic environments into distinct perceptual streams — separating a mixture into individual sound sources based on acoustic cues.

Key Ideas

• Streaming: the perceptual organization of sound over time. Sequential streaming (grouping sounds over time) vs. simultaneous streaming (separating concurrent sounds).
• Grouping principles: proximity in frequency and time, harmonicity, common onset/offset, common modulation (AM/FM), spatial location.
• Primitive vs. schema-driven: bottom-up (acoustic cues) vs. top-down (learned patterns, attention) processes.
• Foundational to all computational approaches to source separation.
