AB  - In our Ultra Low Delay Audio Coder (ULD) a pre-filter which is controlled by a psycho-acoustic model is followed by a quantizer and a predictive coder to code signals in the time-domain. The output of the predictor is entropy coded and transmitted. Predictor and entropy coder form the lossless redundancy reduction part of the coder. Our goal is to improve the lossless redundancy-reduction part for stereo signals. We present and evaluate 6 different alternatives for the stereo redundancy reduction, and we combine those alternatives to obtain a higher compression ratio.
