This paper presents the research result for the four-channel sub-band coding (SBC) with a combination of share [8 8 4 2]. The research method is based on the Wavelet multi-resolution analysis using ATRAC3 algorithm using filters designed by a novel technique of filter bank called “transit-window”. The advantages of the method are as: reduction of ripple of output amplitude response and information lossless at the interface region between two filters. Especially, under wavelet analysis with the change in the base-2 exponential partition factor from SBC [4 4 2] is to SBC [8 8 4 2] and it may be used to rec-ord/read audio and digitally broadcast on internet. The result is obtained by using the Matlab/Simulink modeling for the method.
