    摘要： A method and apparatus for separating and extracting main sound sources from a mixed musical sound signal are provided. A musical sound source separation apparatus may include an prior information signal compressor to compress an prior information signal including a characteristic of a predetermined sound source, a mixed signal divider to divide a mixed signal including a plurality of sound sources into a plurality of segments, a Nonnegative Matrix Partial Co-Factorization (NMPCF) analyzer to acquire common information shared by the plurality of segments, by applying an NMPCF algorithm to the prior information signal, and a target musical instrument signal separator to separate a target musical instrument signal corresponding to the predetermined sound source from the mixed signal, based on the common information.

    摘要： Disclosed are an apparatus and a method for separating sound sources capable of learning distributions of corresponding sound sources based on the assumption that specific sound sources have specific distributions based on interchannel correlation parameter in audio signals providing space perception through a plurality of channels to separate an amount corresponding to energy contribution of the corresponding sound sources from mixture signals. Exemplary embodiments of the present invention can more precisely predict the channel distributions of the specific sound sources included in the input mixture signals and more accurately separate sound sources than a method for separating a sound source based on the channel according to the related art, under conditions that general channel distribution information of the specific sound sources are approximately modeled.
