摘要

We propose the new suppression method of a click noise. A conventional suppression method of a click noise is as follows: 1) detection of a click noise 2) removal of a noise 3) interpolation using a linear interpolation or a spline interpolation. When we use the conventional method, the precision of the suppression is low. On the other hand, in fields of a digital signal processing and a system identification, there are some studies on an estimation method of missing data. Then, in this paper, we regenerate the original signal for the missing data by assuming a click noise to be missing data and applying the estimation method of missing data to a linear predictive model. The proposed method is as follows: 1) detection of a click noise 2) regarding that noise as missing data 3) replacing the missing part with the estimation signal of the original signal for the missing data, and regenerating the original signal. The third processing 3) of our method is different from the conventional method. We describe the detailed procedure of the proposed method and the principle.
