Abstract

With stereo audio steping into people´s daily lives, spatial parametric technology comes to its broad prospects for development. Spatial parameteric technology is a method for stereo compression. In this paper, Construction of new spatial parameter perception two-dimensional model on perception spatial information estimation domain, and Optimization of calculating for the new module, to reduce computational complexity of the system. Spatial Perception Entropy was proposed to improve it. Its computation method which based on Just Noticeable Difference Model avoids separate transforming for cues representation and saves significant computation, optimizing spatial parameter selection and realizing high efficiency spatial audio coding.
