Usage of short wavelets for scaleable audio coding

Panos Kudumakis, M. Sandler

Open publisher page 1 citations

Abstract

In this paper, an in depth investigation and comparison of the performance obtainable with short wavelet filters for low bit rate perceptual audio coding is presented. This a priori knowledge of the short wavelet filters performance evaluation open new horizons in their usage, especially, when combined with the Moving Pictures Expert Group (MPEG-4) requirements for segmental signal to noise ratio scalable audio coding.
