Lemur: A Bandwidth-Enhanced Sinusoidal Modeling System

We \vill present research associated }vith the sound modeling soft$~rare called Lemur. In Lemur, Jve have developed a ne}v extension LOthe sinusoidal modeling technique of McAulay and Qua~ieri to accommodate sounds having significant non-sinusoidal energy. Lemur models sounds as a collection of par[ials having amplitude, frequency, and band!vidth envelopes. Band!vidth envelopes allotv Lemur [o preserve energy and fidelity during pruning and editing operations. Lemur’s synthesis includes a spectral line }videning technique to spread energy a~vay from each partial’s center frequency according to bandividth envelopes.
