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.
