IEEE multimedia, 1996•ieeexplore.ieee.orgMany audio and multimedia applications would benefit from the ability to classify and search
for audio based on its characteristics. The audio analysis, search, and classification engine
described here reduces sounds to perceptual and acoustical features. This lets users search
or retrieve sounds by any one feature or a combination of them, by specifying previously
learned classes based on these features, or by selecting or entering reference sounds and
asking the engine to retrieve similar or dissimilar sounds.
