Abstract

A new algorithm for avoiding overlapping of adjacent frames in order to reduce the block effect is presented. The algorithm is based on forward and backward prediction at the border of frames and has been applied with success to an audio coder based on time-varying wavelet-packet decompositions that uses symmetrical and periodic extension as method for processing frames in isolation.
