| Abstract: | We propose in this paper a two-stage lossless audio coder for stereo signals. The first stage is based on a hybrid approach that uses either a stereo linear prediction or a multilayer perceptron-based (MLP) nonlinear prediction. The second stage is based on two cascaded Normalized Least Mean Square (NLMS) filters that remove the remaining redundancy in the residuals of the stereo prediction. The obtained compression ratios are equal or superior to the best state-of-the-art coders. | ||
