Download Timbre Morphing using the Modal Distribution We present techniques for timbre morphing between two audio signals based on the Modal distribution 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 indistinguishable 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.
Download New SndObj Library Classes for Sinusoidal Modeling We present an object-oriented implementation for sinusoidal modelling based on the C++ Sound Object Library (SndObj). We outline the background to this analysis/synthesis technique and its inclusion in many well known methods of speech and music signal processing. Incorporation of such a well known technique into the SndObj library will enable the development of further audio processing techniques such as vocoding, time and pitch scaling and cross-synthesis on an object-oriented development platform.
