This paper proposes to adapt the techniques of image texture analysis to the context of audio signals. Dynamics of audio frame-level features are particularly difficult to model, although they have been identified as crucial perceptive dimensions of timbre perception. Recent studies have given ample evidence that traditional means to model data dynamics, such as delta-coefficients, texture wind...

We provide new evidence on this “puzzle” using register based Swedish data on the largest sample of twins used so far in the literature. In contrast to previous twin studies, our...
