A Method for Characterizing and IdentifyingAudio Based on Auditory Scene Analysis

摘要

A method for characterizing and identifying audio material using reduced-information audio characterizations basedon auditory scene analysis is presented. In the method described, a single or multi-channel audio signal is analyzedand the location and duration of the individual audio auditory events are identified. The auditory events are used tocreate a reduced information audio signature that can be used to determine whether one audio signal is derived fromanother audio signal. The audio signal comparison removes or minimizes the effect of temporal shift or delay on theaudio signals, calculates a measure of similarity, and compares the measure of similarity against a thresholdproviding a fast, highly accurate and automatic method of signal identification.
