Elimination of impulsive disturbances from archive audio files – comparison of three noise pulse detection schemes
Abstract
The problem of elimination of impulsive disturbances (such as clicks, pops, ticks, crackles, and record scratches) from archive audio recordings is considered and solved using autoregressive modeling. Three classical noise pulse detection schemes are examined and compared: the approach based on open-loop multi-step-ahead signal prediction, the approach based on decision-feedback signal prediction, and the double threshold approach, based on analysis of residual errors. It is shown that the accuracy of the classical schemes can be significantly improved by means of combining the results of forward time and backward time signal processing
