A method of reassignment in sound modeling to produce a sharper, more robust additive representation is introduced. The reassigned bandwidth-enhanced additive model follows ridges in a time-frequency analysis to construct partials having both sinusoidal and noise characteristics. This model yields greater resolution in time and frequency than is possible using conventional additive techniques, and better preserves the temporal envelope of transient signals, even in modified reconstruction, without introducing new component types or cumbersome phase interpolation algorithms.
