Filter Design for a Sinusoidal Synthesis Engine Using Linear Programming and Sound Synthesis Examples 1 Filter Design for a Sinusoidal Synthesis Engine Using Linear Programming and Sound Synthesis Examples

We concentrate on the design of a FIR lter for a fast transform based sinusoidal sound synthesis engine using linear programming and the construction of controller modules that emulate the behavior of contemporary and vintage commercial synthesizers or synthesis techniques. We will show that it is possible to create an entire highly controllable (playable) synthesis framework on top of the transform based engine. For a large class of signals with a sparse representation in the sinusoidal domain the cost for synthesizer modules is relatively low compared to time domain synthesis or processing techniques. Examples are modal synthesis of percussion instruments, combined synthesis and ltering for analog modeling synthesis, and abstract models for FM-like sounds. 1 Filter design for a sinusoidal synthesis engine using linear programming and sound synthesis examples Tom Schouten, Bart De Moor Abstract| We concentrate on the design of a FIR lter for a fast transform based sinusoidal sound synthesis engine using linear programming and the construction of controller modules that emulate the behavior of contemporary and vintage commercial synthesizers or synthesis techniques.
