The Reassigned Bandwidth-Enhanced Method of Additive Synthesis

We introduce a highly manipulable, high delity additive sound model capable of representing transient sounds and sounds having signi cant nonsinusoidal energy. We represent sounds as a collection of bandwidth-enhanced partials having sinusoidal and noise-like characteristics. Partials are de ned by a trio of synchronized breakpoint envelopes specifying the time-varying amplitude, center frequency, and noise content. Breakpoints for the partial envelopes are obtained by following ridges on a time-frequency surface computed by the method of reassignment. The Reassigned Bandwidth-Enhanced Model yields greater resolution in time and frequency than conventional additive techniques, and preserves noise-like and transient signals, even in modi ed reconstruction.
