AUTOMATIC CLASSIFICATION SYSTEM AND METHOD OF MUSIC MOOD USING FEATURE REDUCTION METHOD OF MUSIC SOURCE BASED ON STANDARD DEVIATION

摘要

The present invention relates to an automatic classification system for music atmosphere using a method of reducing the characteristics of sound sources based on a standard deviation and a method thereof. According to the present invention, the automatic classification system for music atmosphere can accurately determine the atmosphere of more music files much effectively by selecting some characteristics of the multiple sound sources to reduce the characteristics and removing noise among the characteristics.
