Digital audio signal filtration based on the dual-tree wavelet transform
Alauldeen S. Yaseen, А. Н. Павлов · Technical Physics Letters · 2015
A new method of digital audio signal filtration based on the dual-tree wavelet transform is described. An adaptive approach is proposed that allows the automatic adjustment of parameters of the wavelet filter to be optimized. A significant improvement of the quality of signal filtration is demonstrated in comparison to the traditionally used filters based on the discrete wavelet transform.
