The sensitivity matrix for a spectro-temporal auditory model
2015 (English)In: European Signal Processing Conference, European Signal Processing Conference, EUSIPCO , 2015, 1673-1676 p.Conference paper (Refereed)
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.
