METHOD AND SYSTEM FOR SEPARATING MUSIC SOUND SOURCE |
摘要 |
PURPOSE: A system for separating musical sound source is provided to efficiently divide a specific sound source in a mixed sound source by reorganizing the mixed sound source into the specific sound source and other sound source. CONSTITUTION: A system for separating musical sound source includes a database(110), a time-frequency domain conversion unit(120), an NMPCF(Nonnegative Matrix Partial Co-Factorization) analysis unit(130), a target instrument signal separating unit(140), and a time domain signal conversion unit(150). The database stores information about a solo performance using a predetermined musical instrument, and transmits the information about the solo performance as a type of a predetermined sound source signal(x1). The predetermined sound source has a significantly great amount of data to include various characteristics of the predetermined sound source. In this case, a great amount of database signals may need to be processed for each sound source separation operation. |
