METHOD FOR EXTRACTING NON-VOCAL SIGNAL FROM STEREO SOUND CONTENTS

摘要

PURPOSE: A method for extracting a non-vocal signal from a stereo sound is provided to be applied to a stereo sound source, thereby enabling a user to appreciate only initially recorded accompaniment music. CONSTITUTION: A difference signal between first and second sound sources is processed(S120). The first and second sound sources are transmitted through right and left channels. An empty frequency component remains wherein the empty frequency component does not satisfies some conditions(S160). Vocal signals are eliminated from the first and second sound sources by time domain conversion(S170).
