Computational 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 کاملAuditory 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 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...
متن کاملPrediction-driven computational auditory scene analysis
The sound of a busy environment, such as a city street, gives rise to a perception of numerous distinct events in a human listener – the ‘auditory scene analysis’ of the acoustic information. Recent advances in the understanding of this process from experimental psychoacoustics have led to several efforts to build a computer model capable of the same function. This work is known as ‘computation...
