TL;DR: In this article, a psycho-acoustically motivated, parametric description of the spatial attributes of multichannel audio signals is proposed, which allows strong bitrate reductions in audio coders, since only one monaural signal has to be transmitted, combined with quantized spatial properties of the signal.
Abstract: In summary, this application describes a psycho-acoustically motivated, parametric description of the spatial attributes of multichannel audio signals. This parametric description allows strong bitrate reductions in audio coders, since only one monaural signal has to be transmitted, combined with (quantized) parameters which describe the spatial properties of the signal. The decoder can form the original amount of audio channels by applying the spatial parameters. For near-CD-quality stereo audio, a bitrate associated with these spatial parameters of 10 kbit/s or less seems sufficient to reproduce the correct spatial impression at the receiving end.

TL;DR: An error model approach is introduced to establish algorithms and their global stability and convergence properties and a number of applications of this error model in adaptive estimation and control are included, in which the new algorithm is shown to result in global boundedness.
Abstract: Parametric uncertainties in adaptive estimation and control have been dealt with, by and large, in the context of linear parameterizations. Algorithms based on the gradient descent method either lead to instability or inaccurate performance when the unknown parameters occur nonlinearly. Complex dynamic models are bound to include nonlinear parameterizations which necessitate the need for new adaptation algorithms that behave in a stable and accurate manner. The authors introduce, in this paper, an error model approach to establish these algorithms and their global stability and convergence properties. A number of applications of this error model in adaptive estimation and control are included, in each of which the new algorithm is shown to result in global boundedness. Simulation results are presented which complement the authors' theoretical derivations.

TL;DR: Reliability was shown to improve with the transformation, where the improvement was comparable to that using Box-Cox, and agreement with the Gaussian was better than using logarithmic, logit, or Box- Cox transformations.
