    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: Provided is an apparatus of separating a musical sound source, which may re-construct mixed signals into target sound sources and other sound sources directly using sound source information performed using a predetermined musical instrument when the sound source information is present, thereby more effectively separating sound sources included in the mixed signal. The apparatus may include a Nonnegative Matrix Partial Co-Factorization (NMPCF) analysis unit to perform an NMPCF analysis on a mixed signal and a predetermined sound source signal using a sound source separation model, and to obtain a plurality of entity matrices based on the analysis result, and a target instrument signal separating unit to separate, from the mixed signal, a target instrument signal corresponding to the predetermined sound source signal by calculating an inner product between the plurality of entity matrices.
