Restoration of Recorded Audio Through Adaptive Noise Cancelling

Abstract

Adaptive noise cancelling (ANC) systems are usually applied in situations where periodic interference must be controlled and this interference has been additively combined with the desired signal. For broadband noise cancellation a reference noise signal of some sort is required to provide an estimate for the noise to be cancelled. This paper presents a frequency domain approach to adaptive noise cancelling with reference inputs which have been provided asynchronously with the source material.
