Abstract
Provided is an apparatus and method for separating music and voice using an independent component analysis method for a two-dimensional forward network. The apparatus of separating music and voice can separate voice signal and a music signal, each of which are independently recorded, from a mixed signal, in a short convergence time by using the independent component analysis method, which estimates a signal mixing process according to a difference in record positions of sensors. Thus, users can easily select accompaniment from their own compact discs(CDs), digital video discs(DVDs), or audio cassette tapes, or FM radio, and listen to music of improved quality in real time. Accordingly, the users can just enjoy the music or sing along. Furthermore, since the independent component analysis method in the apparatus of separating music and voice is simple and time taken to perform the method is not long, the method can be easily used in a digital signal processor (DSP) chip, a microprocessor, or the like.
