Hybrid Independent Component Analysis and Rough Set Approach for Audio Feature Extraction

Audio classification is based on audio features. The choice of audio features can reflect important audio classification features in time and frequency time. The extraction and analysis of audio features are the base and important of audio classification. The most important problem is to extract audio features effectively and make them mutual independence to reduce information redundancy. In this paper, combined with independent component analysis and rough set, a method for audio feature extraction is presented and it´s proved better performance by experiments.
