Abstract
In this paper, structural modifications to the current spatial stereo coding are developed, and two novel complete structures are proposed based on those modifications. Through analyzing the problems of frequency band partition, algorithmic delay, and computational complexity of the current spatial stereo coding on a structural level, 3 schemes, analysis-by-synthesis frequency band partition parallel mono and spatial processing, and filter-bank/transform sharing are put forward. They are shown to be able to solve the problems with reasonable restrictions.
