Parameterized temporal feature analysis

机译:参数化的时态特征分析

摘要

A method (1) for classifying at least one audio signal (A) into at least one audio class (AC), the method (1) comprising the steps of analyzing (10) said audio signal to extract at least one predetermined audio feature, performing (12) a frequency analysis on a set of values of said audio feature at different time instances, deriving (12) at least one further audio feature representing a temporal behavior of said audio feature based on said frequency analysis, and classifying (14) said audio signal based on said further audio feature. With the further audio feature, information is obtained about the temporal fluctuation of an audio feature, which may be advantageous for a classification of audio.
