METHOD AND APPARATUS FOR SEPARATION OF SOUND

摘要

PURPOSE: A device for separating a sound source and a method thereof are provided to extract only a desired sound from various sound sources. CONSTITUTION: An input unit(610) changes the offered signal in to a frequency domain. A processing unit(620) divides the sound source of the converted signal in the frequency band unit. The processing unit aligns the separated sound source through the phase difference of a mixed filter for mixing the sound sources. An output unit(630) changes the aligned sound sources into the time domain.
