AB  - We propose a novel method for exploiting the redundancy of stereo linear prediction coefficients by using adaptive linear prediction for the coefficients themselves. We show that an important proportion of the stereo linear prediction coefficients, on both the intrachannel and the interchannel parts, still contains important redundancy inherited from the signal. We can therefore significantly reduce the amplitude range of those LP coefficients by using adaptive linear prediction with orders up to 4, separately on the intrachannel and intrachannel parts. When integrated into asymmetrical OptimFROG, the new method obtains on average 0.29% improvement in compression with negligible increase in decoder complexity.
