DEVICE AND METHOD FOR DETERMINING SEPARATION CRITERION OF SOUND SOURCE, AND APPARATUS AND METHOD FOR SEPARATING SOUND SOURCE WITH THE SAID DEVICE |
摘要 |
PURPOSE: A sound source division reference determination device and a method thereof are provided to detect a sound source direction in a noise environment by using an ITD(Interaural Time Delay) value and an IID(Interaural Intensity Difference) value. CONSTITUTION: A histogram generator(110) generates a histogram related a sound source direction including the input signal based on an SNR(Signal to Noise Raito) value or an input signal energy value. A noise area detecting unit(120) detects a noise area from an input signal. A sound source division standard determination unit(130) determines a boundary value as a standard value for dividing the sound sources. [Reference numerals] (110) Histogram generator; (120) Noise area detecting unit; (130) Sound source division standard determination unit; (140) First power unit; (150) First main control unit
