Embedded Stereo Coding Algorithm for Stereo Voice Codec

Abstract

In this paper, an embedded stereo coding algorithm is proposed. It is developed for the multiple participants video conference. The proposed algorithm is an embedded stereo tool, which can be grouped with any mono voice codec (e.g. AMR-WB, SILK etc.). Subband coding and transform coding methods are used for the proposed stereo tool. Simulation results show that the proposed the stereo voice codec algorithm has a better performance and lower delay in contrast with AMR-WB+ standard.
