AB  - A new high-quality multichannel audio compression algorithm based on the MPEG-2 Advanced Audio Coding (AAC) is presented in this paper. The Karhunen-Loeve Transform (KLT) is used on multichannel audio signals in the preprocessing stage to remove the interchannel redundancy. Then signals in the decorrelated channels are compressed using a modified AAC main profile encoder. Experimental results show that compared to the original AAC, the proposed algorithm achieves better performance with the objective mask-to-noise-ratio (MNR) measurement while maintaining similar computational complexity.:
