public abstract class AudioFeature
extends Attribute
implements Serializable

An audio feature is a special attribute designed to describe characteristics of audiostreams. A audio feature is the result of a audio feature extraction process.

Beside describing the characteristic of audio streams, audio features also support comparing two audio streams. So based on the supported characterization a metric has to be implemented, which allows to compute the distance (similarity/dissimilarity) of two audio streams.
