Abstract :
One step towards more realistic speech communication is the move from monophonic to stereophonic sound transmission. Stereophonic speech coding has been explored in the past with the use of cross-channel “cancellation” prediction combined with ADPCM. While this solution and other multi-channel audio techniques can be applied to speech coding there are some fundamental reasons that may limit their use in newer speech coding technologies. This paper investigates the application of cross-channel prediction in the framework of stereophonic code excited linear predictive (CELP) coding
