Auditory Scene Analysis: Computational Models
Listeners have to make sense of a complex acoustic world containing overlapping sound sources that must be organized into individual auditory objects. Computational auditory scene analysis concerns the use of algorithms inspired by human sound perception whose aim is to extract properties of constituent sound sources in a complexmixture. Starting with representations based on models of how soun...
متن کاملAuditory Scene Analysis: Computational Models
Human listeners have a remarkable ability to separate a complex mixture of sounds into discrete sources. The processes underlying this ability have been termed ‘auditory scene analysis’ (Bregman 1990; this volume). Recently, an interdisciplinary field known as ‘computational auditory scene analysis’ (CASA) has emerged which aims to develop computer systems that mimic this aspect of hearing (Ros...
متن کاملComputational Models of Auditory Scene Analysis: A Review
Auditory scene analysis (ASA) refers to the process (es) of parsing the complex acoustic input into auditory perceptual objects representing either physical sources or temporal sound patterns, such as melodies, which contributed to the sound waves reaching the ears. A number of new computational models accounting for some of the perceptual phenomena of ASA have been published recently. Here we ...
متن کاملBregman's Chimerae: Music Perception as Auditory Scene Analysis
Research into the perception and cognition of music listening often contains implicit assumptions about the nature of the underlying mental representations, and about the relationship between "auditory processing" and "music perception". We attempt to highlight and problemitize some of these assumptions and to provide a more cognitively appropriate model for music perception and cognition, base...
متن کاملA computational model of auditory scene analysis
Various grouping attributes have been translated into successful signal processing techniques that may be used in source separation, e.g., to separate speech from background. However, separation is not enough to know: What is the source of the sound? A next step beyond primitive ASA is schema-based ASA, to give meaning to the source, i.e. to map bottom-up audio features to the meaningful conten...
