Computational auditory scene analysis

Computational auditory scene analysis

Computational auditory scene analysis (CASA) is the study of auditory scene analysis by computational means [1]. In essence, CASA systems are "machine listening" systems that aim to separate mixtures of sound sources in the same way that human listeners do. CASA differs from the field of blind signal separation in that it is (at least to some extent) based on the mechanisms of the human auditory system, and thus uses no more than two microphone recordings of an acoustic environment. It is related to the cocktail party problem.
