Abstract
This paper describes an efficient one dimensional wavelet adaptive coding algorithm for the compression of audio signals. The new algorithm has the property that the most appropriate wavelet filter is selected from a library of wavelet filters according to a proposed switching criterion. This algorithm yields a system that can adapt to the time variance of a signal. Simulation results are demonstrated for several audio signals to show the superior performance of the new method.
