APPARATUS FOR GAIN CALIBRATION OF MICROPHONE ARRAY AND METHOD THEREOF
摘要
PURPOSE: A gain controlling device and method thereof are provided to adjust bandwidth of a sound signal by using the updated weight. CONSTITUTION: A micro phone array includes at least two microphone which is arranged on the same surface. A frequency converting unit(110) converts a plurality of sound signal received from the microphone array into a signal of each frequency. A weight calculating unit(120) maintains a plurality sound signal which is converted into the frequency area. The weight calculating unit calculates a plurality of sound signal according to the frequency component. A scaling unit(130) adjusts an amplitude of a plurality of acoustic signals by using the calculated weight. The weight calculating unit calculates the weight.
