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 method and apparatus to eliminate noise from a plurality of channel audio signals in which surrounding noise is mixed. The method includes detecting an existence of noise in frame units by averaging a plurality of channel input signals and estimating a noise signal of a noise-detected frame, and subtracting the estimated noise signal from each of the plurality of channel input signals.

摘要： A method and apparatus to correct erroneous audio data when reproducing the audio data in a magnetic tape audio system having a cylindrical head structure, and a digital audio signal processing system. A method of interpolating erroneous audio samples between normal audio samples in a reproducing apparatus, in which a plurality of normal audio samples and erroneous audio samples are generated periodically comprises counting a number of erroneous samples based on a number of error flags, and when at least one erroneous sample is counted between a first normal sample and a second normal sample, calculating a first value obtained by adding a first product of the first normal sample value and a first weight and a second product of the second normal sample value and a second weight, calculating a second value located on a continuous line of the first normal sample or the second normal sample, and setting a mean value of the first value and the second value to a sample value of a position where the error is generated. The audio sample interpolation method corrects audio errors generated in reproducing apparatuses using a cylindrical head or a rotary head and remarkably reduces harmonic components generated when the errors are corrected, thereby increasing clarity of reproduced sound.
