ACCOMPANIMENT/VOICE SEPARATING DEVICE USING AN INDEPENDENTLY INTERPRETING ALGORITHM IN THE SECONDARY OMNIDIRECTIONAL NETWORK AND A METHOD THEREOF, PARTICULARLY CONCERNED WITH REMOVING A VOICE SIGNAL FROM SIGNALS OUTPUTTED FROM AN ACOUSTIC PLAYER

摘要

PURPOSE: An accompaniment/voice separating device using an independently interpreting algorithm in the secondary omnidirectional network and a method thereof are provided to use an independently interpreting algorithm for estimating a mixing process of signals with regards to acoustic signals where accompaniment signals are mixed with voice signals, thereby separating the voice signals from the accompaniment signals within the shortest time. CONSTITUTION: An independent interpreter(110) receives output signals consisting of accompaniment signals and voice signals, and outputs the first, second, third, and fourth multiplication coefficients. An accompaniment signal selector(120) outputs a multiplex control signal having the first logical state by corresponding to the second logical state of the most significant bit of the second multiplication coefficients, and having the second logical state by corresponding to the second logical state of the most significant bit of the third multiplication coefficients. A filtering unit(130) generates the first output signal among output signals which add up two signals for processing R and L channel signals with the first and third multiplication coefficients, and generates the second output signal among output signals which add two signals for processing with the second and fourth coefficients. A multiplexer(140) selectively outputs the first or the second output signal.
