Abstract [en]

Perceptually optimal processing of speech and audio signals demands distortion measures that are based on sophisticated auditory models. High-rate theory can simplify these models by means of a sensitivity matrix. We present a method to derive the sensitivity matrix for distortion measures based on spectro-temporal auditory models under the assumption of small errors. This method is applied to an example auditory model and the region of validity of the approximation as well as a way to analyze the characteristics of the model with subspace methods are discussed.
