This article presents methods for clicks detection in degraded audio recordings. It begins with a brief description of the method implemented in first instance for the detection of clicks in audio sources based on linear prediction. Looking for an improvement of the results obtained with this method, we propose a method based on sinusoidal modeling for the confirmation of the clicks. This method discards clicks that were wrongly detected. This allows the detection of clicks of small amplitude avoiding wrong detections. The results obtained by this method are shown, confirming the good operation. Finally, the method implemented for detection of clicks in naturally degraded audio sources is presented.
