AB  - This paper presents a novel lossless multichannel audio coding algorithm to remove inter-channel redundancy. We employ an Integer-to-Integer Discrete Cosine Transform (INT-DCT) to perform inter-channel decorrelation after quantization of Modified Discrete Cosine Transform (MDCT) coefficients of individual channels. When compared with a Karhunen-Loeve Transform (KLT) based approach our new method has three major advantages: 1) avoids quantization noise spreading to other channels; 2) computational simplicity; 3) uses less overhead information (a quantized covariance matrix or eigenvector is avoided in our algorithm), while having a similar decorrelation capability.
