Abstract

We present techniques for timbre-morphing between two audio signals based on the Modal time-frequency representation of music signals. A signal synthesis method is described which resynthesises signals from Modal distributions. Direct resynthesis from the original signal produces a timbre that is almost undistinguishable from the source. In deciding which salient features to morph a relational graph representation of timbre is used and linear interpolation and non-linear warping are applied in performing the morph between Modal distributions.
