Auditory Scene Analysis

·   Auditory Scene Analysis (ASA)

- "perceptual organization of sound"
- extract useful information about environment
- overlap (time + freq) is the general rule

·   Computational ASA (CASA)

- models of human sound processing
- separate sources in mixture
(`perceptually coherent' sources i.e. subjective)

·   Qualities defining CASA

- unknown number of sources/events
- events have specific time support
- events overlap (?)

·   which excludes...

- double-vowel separation
- directional filtering
- seeded signal tracking
