The aim of sound morphing is to obtain a result that falls perceptually between two (or more) sounds. In order to do this, we should be able to morph perceptually relevant features of sounds instead of blindly interpolating the parameters of a model. In this work we present automatic timbral morphing techniques applied to musical instrument sounds using high-level descriptors as features. High-level descriptors are measures of the acoustic correlates of salient timbre dimensions derived from perceptual studies, so that matching the descriptors becomes the goal itself to render the results more perceptually meaningful.
