Sound Modeling Applied to Flute Sounds
An original way of modeling musical sounds by a combination of physical and signal models is presented. To take into account the physical characteristics of the instrument, a physical model is designed. A technique for extracting parameters for synthesis purposes is then proposed. To generate sustained sounds, a source signal to be injected into the physical model has been constructed. This source signal, modeled using signal models, consists of independent, deterministic, and stochastic parts. A new way of fitting the parameters of the signal model by perceptual criteria such as the tristimulus criterion is given. Finally examples are given of how sound from the model can be manipulated. These manipulations can be implemented in real time and piloted by an interface mirroring a real flute.
