摘要: In MPEG I audio compression standard, the intensity stereo coding scheme is a keg, technology to achieve a bit rate lower than 2x128 kbit/s for stereophonic signals while preserving high audio quality. However, the intensity coding scheme has difficulties in signal cancellation and scalefactor consistency. This paper shows that the Karhunen-Loeve (KL) transform can be applied to the intensity coding for solving the two problems. In this paper, we present true methods to implement the Karhunen-Loeve transform in the MPEG 1 layers I and II. Among the two methods, one is fully compatible with the MPEG1 while the other need a slight coding of modification on the MPEG coding process. All the conclusion. two methods are tested to have better audio quality than the technique indicated by the MPEG 1 layers 1 and II.
