Title:
METHOD AND DEVICE FOR AUDIO SIGNAL CLASSIFACATION
Document Type and Number:
WIPO Patent Application WO/2010/108458
Kind Code:
A1
Abstract:
This invention discloses a method and device for audio signal classification, relating to the field of communication technology and solving the problem of high-complexity in audio signal classifications in the prior art. In this invention, after an audio signal to be classified has been received, a tonality characteristic parameter of the audio signal in at least one sub-band is acquired, and the type of the audio signal to be classified is determined according to the acquired characteristic parameter. This invention is mainly applied in the scenarios of classifying audio signals, enabling the simpler method to implement the audio signal classification.
