摘要： An audio data processing apparatus and method to reduce wind noise. The apparatus includes a wind noise detecting unit to detect a wind noise section from an input audio signal, and a signal processing unit to reduce a low-frequency band signal of the input audio signal in the detected wind noise section. The apparatus determines whether wind is present and automatically reduces wind noise based on the determined result. Accordingly, the apparatus can effectively reduce wind noise.

摘要： A noise removing apparatus and method usable in a portable recorder to remove noise and enhance a voice signal when the voice signal with noise is input to the portable recorder. The noise removing method includes dividing an input signal into a high frequency component signal and a low frequency component signal, adjusting a magnitude of the high frequency component signal by comparing the magnitude of the divided high frequency component signal and a magnitude of the low frequency component signal, enhancing a clearness of the low frequency component signal by filtering the divided low frequency component with an adaptive filter, and adding the magnitude-adjusted high frequency component signal and the clearness-enhanced low frequency component signal.
