Abstract

A wavelet-based method for denoising broad-band noisy audio signals is proposed and implemented. The method is a modified algorithm based on the method of Coifman and Wickerhauser (1992). The modified algorithm shows noticeable improvement in quality and computation overhead compared to the original method when denoising digitized music signals with different levels of additive broad-band noise. Several implementation issues are described.
