Sound signal analysis can involve a large variety of signal processing methods. This work addresses the analysis of families of sound signals through linear transformations that map signals to each other. These transformations are modeled as Gabor multipliers, which are defined by pointwise multiplication with a given transfer function in the timefrequency (i.e. Gabor) domain. We develop new approaches for the estimation of such transfer functions, and propose corresponding efficient iterated shrinkage algorithms. The estimated transfer functions can be used for various purpooses in signal analysis and processing. This paper describes applications to sound morphing.
