Detection of clicks in audio signals using warped linear prediction

Warped linear prediction (WLP) is applied to a model-based method to detect impulsive disturbances in audio signals. According to simulations performed on artificially corrupted audio signals, the adoption of negative values for the warping factor favors the click detection scheme. As a consequence, for equal levels of missing (false) detection, the WLP-based scheme yields a consistently lower percentage of false (missing) detection than the conventional method.
