This paper proposes signal restoration from clipping effect without prior knowledge. First, an interval of signal including clipped samples is analyzed by recursive vector projection. By analyzing the neighboring samples of the clipped interval and excluding the clipped interval in the analysis of similarity, signal estimation in the clipped interval is estimated as a by-product of the analysis. Since the estimation holds consistency with the neighboring samples, the restored signal does not suffer from click noise. Evaluation of the clipping restoration with various audio signal ascertained that the proposed method improves signal-to-noise ratio.
